Tell these guys to start making some eMTB internal gear hubs. There is a pretty big hole in the market for sturdy, wide range IGHs that can handle hi power ebiles.
7:40 I had the same thought in mind - a bigger difference in ratio could allow small jumps between gears AND a large range, by eliminating some of the overlap. I agree it is the right move of Classified to start with what people are familiar with.
Keep the 2x mech up front, with the hub in back you would get ratios of 0.5 and 0.7 with a standard setup. But with this front chainrings of 53 and 44 also start to make sense.
Schlumpf has a very similar system to this, but it sits in the chainring instead, they have two different gearing ranges both are bigger than the classified hub. 1:1-1:6.5 and 1:1-1:2.5. So kinda what Cade was asking for.
you don't want to eliminate overlap. overlap is a good thing. Currently, when shifting at the front, you have to shift in the opposite direction by how much? 2, 3 gears? Imagine having a setup with no overlap at all... you'd have to shift right up to small:small, shift up the front and shift in the opposite direction the whole 11 gears. Now imagine how annoying that would be, even more so when you happen to be on a climb or a headwind situation, where the right gear at the moment happens to be between small:small and big:big... it would drive you nuts.
@@yurimow Yes, the gearing is extremely wide, but it's mostly meant for recumbents, where you might need gearing for 60-70kmh+, while still having very low gearing for climbing. Their 1:2.5 drive works quite well for this.
@@yurimow No you wouldn't. They aren't talking about overlap in range. They are talking about overlap in ratios making some gears redundant. There's no need to have that once you eliminate chain line considerations. Understanding when and how to shift the cassette alongside the internal hub is no different than with 2 chain rings
I ride the Classified Hub on Zipp 353s on my Wilier road bike and am very happy with it! It's physically wired into the left DI2 shifter which eliminates the need for the sprint button that Classified provides. It was a little effort to perform the wiring but not terribly difficult. Rather than the toggling on or off that the sprint shifter provides, the DI2 integration allows one shifter button to put the hub in 1:1 mode (1) and the other shifter to put the hub into reduced (2) mode. That simplifies matters, but since the Hub integrates into my Karoo head unit I have a field on my screen which displays a 1 or 2 to indicate the state of the Hub mechanism. I installed a k-edge chain keeper on my 52t chainring to keep things in place. It's great technology, but better integration with Shimano or SRAM would be a real plus.
Could just keep the 2x and use this for mega range. Also I'm not sold on the chainline argument. I'd have thought you're more likely to have a more efficient chainline if you use 2x sensibly (ie not cross chaining) rather than one ring for all the cogs
I am with you on this. I use a rather large and heavy cassete 11-34 with a front 50-34 and get 1:1 ratio (105 R7000) that is not enough for steep hills with 10%+ grades on long rides (200km) and I would love to go for something more ultegra like with 11-28 rear and up a bit on from 52-36 crankset and 11-28 on the cassete with my climbing wheels with Classified hub ( not deep aero for flatter days ) and have a resulting range increased to 0.9 rather than 1 : 1….
Same, and I commented similarly before seeing your comment. I believe it was Friction Facts that confirmed this, that in use, 2x is always more efficient than 1x
Wait...Did he REALLY just say one advantage is that "you're not cross-chaining"??? He can't be serious...ANY 1X setup creates a BIGGER cross-chaining problem than a 2x or 3x setup; that's just a plain fact. This may eliminate the need for a front derailleur, but (from a chainline perspective) you still have a 1x setup here. AND you're adding weight to the hub. And to be honest, let's give this credit where it's due, but not over-inflate the innovation. This is really nothing more than an internal geared hub with Di2 shifting, with a cassette added. SRAM has effectively done this already (minus the eShifting). Not drinking the kool-aid, sorry. "NEXT"
Fun fact, cross-chaining is not as inneficient as it's touted to be. In fact, big-big cross-chained is more efficient than equivalent small rings ratio, because of the shallower bends the chain has to make.
I like how they compare their "perfect chain line" only to crossed chain on 2x systems, but they forget to mention that if you use your 2x properly chain line is much better than with 1x. I'm a big fan of 1x myself, but this kind of data presenting is borderline with lying.
Agreed - if you’re in your lowest gear for example, so you have the reduction gear loss plus a worse chainline than a 2x, it’s definitely going to be less efficient. Is it enough to worry about? Dunno, but the fact that they effectively lie about it doesn’t inspire confidence.
I like this plan, but would remove cogs off the cassette to maximize chain efficiency by eliminating cross chaining, maybe a 2x2x6 which essentially would give you 2 additional gears over the 2x11 standard setup
It would be great if it actually had a lower difference ~12% between high and low. Then you could run a 11-40 and take the big jumps between gears and each one would have an intermediate 'classified' gear and because it shifts so instantly it doesn't matter unlike if you were shifting your front ring every gear shift. It gives the equivalent of a true 24 speed setup where there are no repeated gears and almost even spacing and you don't have to shift down the whole cassette when you shift from high to low ratio.
In my opinion, the issue with this system is that you'll need to get a number of such hubs in order to use different wheels. For example, on a gravel bike that you also use as a road bike. Or else, if you notice that you have a broken spoke just before your ride. This was my major criticism of the PowerTap rear wheel power meter.
Francis i think you’re spot on with the much lower ratio! With full electronic sequential shifting you would then just need for one lever/button for upshift and the other for downshift. If each was configured for one ‘blip’ one gear, and longer pressure, shift till released, how cool would that be.
Have a pair of classifieds wheels on my gravel bike and the were flawless all summer. There is one not talked about issue. Serviceability, on a standard set of hubs cartridge bearings can be replaced easily. When the non standard sized bearings need replaced in this hub, it needs to back to classified or the warranty is lost. In short the planetary gears are solid but cartridge bearings are cartridge bearings and will need replaced at some point. If that makes sense.
Heavier and no mention of the watts wasted with a “planetary” gearing method. It’s usually 4% minimum. That’s a lot of wasted watts. I note their ambassadors are not racing anymore…
Back in the late 1990s I had a Bike Friday travel bike with a Sachs/SRAM 3x7 DualDrive system. That is, 3-speed internal hub combined with 7-speed cassette. I think Sturmey-Archer still makes a 3-speed hub with a freehub that will take 10-speed (and some 11-speed) cassettes. The big innovation here seems to be that Classified has added electronic shifting. And maybe made the hub lighter by limiting it to 2-speed.
@@Cade_Media It did the same job as a triple crankset, with less maintenance. The simplicity of a single chainring was very useful on the travel bike. It was heavy, though, and getting the shift cable set up exactly right was a bit fiddly. Plus the internally geared hubs are inherently less efficient since you are adding extra parts to the transmission - the planetary gears inside the hub are not 100% efficient!
@@Cade_Media Bad and complicated, heavy rear wheel and very hard to catch system how to use ..instinctivly. Thought that its cool but after using became clear not. Swedish bikes in 70s had similar hubs.
Now that I have finished watching the Cyclocross... This is bloody brilliant! I hope that the big manufacturers decide to pay a licence fee (or something similar) to use/replicate this....
With cyclocross i am waiting for the first one to use an rohloff with an belt. They get so dirty in the first minutes that an can’t be performing at it’s peak level.
that 363g weight difference is massive, especially considering you still need to add the weight of their special skewer and wireless shift module. that's pushing on 1 pound of weight added vs. only stripping 100-160g for a front mech plus 25g for an inner chainring. love the innovation but that is a heck of a penalty in not an ideal location to be carrying it handling wise.
@@Cade_Media fair points there but it is a cutting edge tech and something that should be desirable to roadies for several reasons. for touring and ebike duties it's ideal. i'd love to see a version that eschews all derailleurs.
Very cool piece of tech. I immediately started fantasizing about a 3T Strada, Parcours Chrono + Classified hub, and Sram Red eTap AXS 1X groupset. Epic.
Interesting concept. I can see this mostly on gravel and mountain bikes. Turning a one by into a two by without a front derailleur to get ripped off. On the steep logging roads here in Oregon, it is easy to run out of gears, this would help a lot. The price will come down if this gets popular. Nice review, thanks.
I dunno about that. I think the roadies are more apt to still use 2x because they tend to pedal on the downhill, and they just tend to go faster. I'm not in the best shape, but a 1x with 32t up front and a 10-52t in the rear can get me up just about anything I want in my area in california- steep, punchy climbs. I dunno. Maybe it would be great though.
@@spencergiles72 sure, but I don't think many people care about smaller gaps. Hence the popularity of 1x. I'm sure some people would love it, but the classified system is SO expensive. Is having a better cadence (something mountain bikers don't generally care about) worth it? I guess that will be up to the individual people to decide.
A good point about it being 0.7 and 1 surely there will be a bunch of equivalent gear ratios in there just like you get with a normal 2 by. I guess it depends on the cassette used but a bigger jump in ratios would prevent some of the overlap. Would be a bit odd though going from the smallest cog in the "little ring" and having to sweep back to the biggest cog in the "big ring".
Evasive answering from the Classified guy on efficiency... most of us don't cross chain too frequently, how is the efficiency compared to a well maintained well lubed not cross chained configuration? I guess it has to have a bit more loss?
Perhaps you could take a look at the Schlumpf drive? A very similar system, but mounted on the chainring. They also have several gear ratios to choose from; 1:6.5, 1:2.5 and 2.5:1, all bigger ratios from the Classified.
It's cool tech and good to see that they are making first steps into the market, having wheel partners (including Mavic) is a good start. Nothing wrong with re-thinking something archaic as a front derailleur but I think, it'll stay a nichè product, just because it is expensive and most likely be paired with expensive components such as electronic groupsets and premium wheels in most builds.
For the efficiency thing, 2x is inherently more efficient due to chainline. When in the small ring, you're in larger cogs, and when you're in the large ring, you're in the smaller cogs. Extreme cross chainring is reduced. Ideally, I'd like to see a cassette with 12sp spacing, but just 9 cogs or so, eliminating the smallest (hardest) gears. Put a bigger big ring to compensate, and use the hub for easier range. Lower friction due to actual better chainline, and lower friction from removal of inefficient cogs with few teeth.
"when you're in the large ring, you're in the smaller cogs" The rationale is that you are much better off in the large ring, even when you're upshifting to larger cogs (more efficient riding large-large). Current 2x unfortunately will result in a bad chainline, and classified (rightly) claims their system enables you to keep a reasonable good chainline while riding large ring, large cog.
@@l.d.t.6327 in a traditional double chainring setup, there is an efficiency crossover around the second or third largest cog. You will have lower friction in the small ring and equivalent cog vs being in the large ring and second largest (and of course largest) cog. This is because at that point, chainline inefficiency in the large ring overrides lower efficiency from smaller gears. As a general rule, friction increases markedly when gears have fewer than 16 teeth. Above that, the difference in friction losses of different tooth counts is greatly reduced (but still present).
@@n0ch91c3sI see no everyone including myself riding in 52/53 in the front and up to 21 in the back. You simply don't go to the small ring unless you have to for longer or steeper climbs. There are plenty times you could do with a better chainline in the big ring. I had synchro shift for a while but ditched it.
if you think about it, kit includes the cassette/shifter too and if you'll save money just by getting the 1x specific brifters/crankset and removing the FD, it's not bad. it's not cheap but definitely not overpriced.
@pipol champ 1400€ for a hub, truh axle, shifter and casette and you still need to build it into a wheelset. Can’t sell in the future, not officially integrated with sram or shimano and can’t service the hub yourself without voiding your warranty. Pretty hard sell for me at its current state. They need to offer a whole drivetrain with shifters and hydraulic brakes. Team up with a chinese brand and target high margin market i.e. roadies and triathletes. Trickle down bikepacking/gravel/allroad bikes where this system could actually make a difference (ratio without overlap).
I think this could be revolutionary if they would not try to use their own cassettes. Just let us use SRAM XD or microspline hubs and I would be all over this. Additionally, like you said, the genius of this would really shine if they lowered the gear ratio to 0.5 or 0.3. Imagine a 1x12 10-50t SRAM Eagle Mullet setup with one of these hubs setup for 0.3! It would be an absolute monster. I also don't understand the chainline and chainring limitations... If I am using my existing 1x derailleur, then why can't I use any chainring size I want?
I find it odd that this is perceived as an innovative product. As I have a 2012 Moulton TSR27 which is fitted with a SRAM Dual Drive, so I have a single chain ring (replaced with a narrow wide one for chain retention) and a 3 speed (not 2) rear hub. It works very well - yes it's old technology so has a cable, but my gear ratios are from 20 to 106 inches! The dual drive goes back to the 20th century but was discontinued in 2017, I believe Sturmey Archer do an equivalent with a slightly lower ratio change of 33% rather than 36%.
Quite! I have one too and it works very well, don't have to worry about cross chaining and can shift while stationary. People can be so peculiar at times!
Looks very interesting. I would have thought having a small switch would be the better option rather than a button. You’d know which gear you were in immediately by feel alone. Love the idea of no lag though!
A 34 tooth Ultegra ring is 34 grams, the Ultegra front mech 90 grams - so, the weight difference is still hefty (for weenies, that is). Also, the blip and the battery/transmitter on the bars might add some grams as well. Intriguing still, because fully encapsulated and thus out of the way of weather and wind. Wondering how the abrasion inside the hub might change if used under high loads compared to "easing off". Bummer that you need a thru-axle and thus, disc brakes for these, if I look at that correctly?
Maybe head units will be able to integrate with it. At then you could glance down at your head unit and see what gear you are in. It should be more than possible since SRAM and Shimano already does.
considering how fast Shimano removed di2 function from Hammerhead once SRAM bought them I don't expect much integration support for this on Shimano shifters.
Extremely well built and developed product however have they solved a problem? New gen front mechs are almost flawless and does anyone want to shift at up to 1000w? I get flicking through cogs at the back at high power but does anyone change front ring at high power? And obviously the price is mental
this may seem unnecessary for roadies but it is a HUGE upgrade for MTB especially for XC/enduro bikes, we can climb up punchy/techy/loose sections without needing to install a 50 tooth cassette AND STILL retain that much needed 1x setup. this would mean easier/balanced control on the rear end when doing berms/jumps/tailwhips whilst improving the RD shifting performance because of the smaller transition between the (now-smaller) easy cogs of the cassette. if they'll bring the cost down this would explode like dropper posts did.
Totally agree on the larger drop for gravel and touring and the like. In a standard set up you are overlapping something like 6 gears. A little fiddling with bike gear calc shows me no overlap on an 11-28 comes at the equivalent of 53/22 chainrings.
I just don't get, why they are not marketing it to triathletes or time-trialists. It gives an aero advantage, weight is less important and the blip-style shifters are farely common there. Imagine a disc-wheel with this tech! A 58-14 and the option to go much lower at any climb.
@@jimsonjohnson3761 and the effectiveness and aerodynamic advantages of a single-speed drive, that you could still ride on a shorter track with climbs don't weigh that up?
I have a button in that position on my E-Bike for changing power level and I have adapted to using my pinkie to activate it when I'm on the hoods. No big deal.
Been waiting on this for a while. Still crazy money but the tech is very interesting. Like as EV cars comes in, the instant torque and no more "gear shifting" requirement is "a new thing". Very cool. This would be awesome on a MTB as well; lots of up/down shifting in those conditions.
Interesting technology but does a market for this really exist? Like all new tech, prices eventually come down but that is if they sell lots. Here in Canada I see that a high-end shop in Toronto is offering a wheelset with the hub for C$4150, or nearly C$4700 with tax. I have never had an issue with a front mech that would warrant getting rid of it and I appreciate its simplicity. Nicely done video, however.
Great to see Dov again on your channel Francis, post 2022 Kona world champs week 👍. Once Classified have integration from Shimano & Sram giants, its popularity is surely set to soar? Parcours are set to do well 👌
The real value in this is how it will influence frame design. A 1x bike with effective 2x utility can accommodate wider tires and a have sturdier bottom bracket housing. I wouldn't be surprised if Classified ends up being acquired by a firm with a long history of acquiring other companies, and a pioneer of 1x: SRAM
While I am excited about the premise of an effective 1x road design, this should be great for MTB and gravel too...rather than running the typical "pizza sized" cassette, you can apply a smaller cassette with tighter ratios. Tons of potential here.
Big advantage to this involves the tire clearance for the rear tire. Chainstay shape and size requires the consideration of many things. With a Classified system, you possibly gain tire clearance.
Presumably it is like Campy’s ultra shift down shift. But without the risk of dropping your chain when you drop down. So if you had the Campy button and this or maybe Di2 on the mega fast shift you can drop 1,2 or 3 ratios when you shift both at the same time. In the end though they need their own group set.
I have been following Classified for a while now - and I'm currently waiting to hear mor about their MTB lineup, as that should make it possible to work with my GRX812 on my gravel bike for much larger range on a 1x11 speed drivetrain.
Just use sram 1x12 eagle axs mix all the range, less gap between gears and much cheaper than the proprietary classified hub where you also can only fit their cassette. Shimano still makes the best Fishing reels though.
I'm pretty sure that their hub will be boost only since it's the absolute main standard on the market and therefor can't be used on gravel bikes with few exceptions like the salsa cutthroat.
I've run an 18t difference upfront before, with the 30t from grx600 and the 48t from grx810, and to be honest there is a point where there's too much front difference. Because changing 4 gears at once on the back to compensate for each front shift gets really old quite quickly. I think a 3x option would be far better.
will be keeping a keen eye on this since it feels like they are only just scratching the surface of what this allows - similar to what some frames were doing when only 1x. chainstays and seat tubes can be reshaped. a wider spread with realiable shifting would also allow you to keep good gears for the flats while getting a lower gear for the long climbs...currently a chainring trade off
I think it is very easy to fix the issue of now knowing what chainring you are in. It could be displayed on the head unit of most cycling computers, or a simple indicator (e-ink, LED) could be put on the bars, and this would be connected to the bar end plug. A key advantage is that you can move the chainstays outboard, when combining with a T47 BB shell, and this is what will give you more tire clearance while at the same time removing the front chain ring. Finally, I think it is important to give free licenses to any manufacturers of cassettes. If they don't do that, there won't be incentives for companies to develop the complicated 3-D printing to reduce the costs of making the cassettes, and this thing won't take off on a large scale.
Can you run a classified hub with a double at the front to give you even more gears! Or maybe like an overdrive gear for sprinting? Or a gear that sits between a small ring and a big ring?
So it enables cross chaining and has more moving parts (more drag) yet the guy from classified says in the video that somehow this hub changes physics. Not sure about that mate a "traditional" drive train is far more efficient. Still an interesting concept. Also why are we adding more weight to wheels.
This would be best on an emb with the LCD display to show which gear you are in, would also extend the battery life allowing you to switch to the larger gear for flat section enabling you to go faster to save the battery assistance kicking in
I recently test rode a Pearson bike with a Classified set up Positives: + instant gear change + reliable gear change Negatives: - very high cost - blip button is not in an ergonomic place - you still get the same overlapping gear ratios as a 2x - adds weight to a 1x system - is a very high tech solution to the solve the same problem as a front mech has done for decades It’s basically a rich persons toy and way up the list of expensive unnecessary upgrades I assume Classified are just looking to get bought by Sram or Shimano
The thing that would worry me is front mechs are pretty simple mechanically speaking, but a hub that's got some clever gearing tech going on inside it...what happens if it breaks? how do you maintain it longterm ?. Sturmer Archer hubs were never much fun to fix.
Baloney. SA Parts are ALL available, unlike complicated Shitmano crap.SA hubs can be rebuilt blindfolded almost. I have a 2017 X-RD3 and 2012 XL-RD5w. Although the 5w did have a machining glitch causing the 2 key nubs to catch on the edge of the hole going into the planet part. I filed and grinded mine with a pen diamond bit engraver. Goes like a charm now. My tour bike is 120 lbs loaded. My Rohloff14 has ZERO problem keeping up with deFaileur bikes at half the weight. LOL.
Great video Francis. Love the tech, but I’m not sure the value proposition is really clear. If I’m already having to shift manually, and think about it, the speed of the shift doesn’t really mean much to me. It is elegant tech, just fixing a problem that might not exist?
Yeah, but if you've got this kind of money to spend and wanted a IGH you'd get rid of the derailleur altogether and bung a rohloff hub in, like many cycle tourists do. Or sacrifice a bit of range and quality and use a Shimano Alfine 11.
Lots of potential in this system. The opportunities for an all-road option (say a road big ring and cassette but a 0.6 ratio) and a TT option (so you can use your standard TT bike on sporting courses) look especially interesting. If the tech matures, and they can drive the cost down and eliminate some minor niggles (can't see what 'ring' you're in, no SRAM integration, etc), I'd be very interested.
Amongst Others must be very rich, that guy's an investor in nearly anything at this point! Jokes aside, how often do you shift between front chain rings under load? For rear shifting a derailleur is significantly more efficient than a hub, how is it different here? And if they managed to solve the efficiency issue, is it an option to make a rear hub then?
I would love to see someone set it up with front derailleur as well, a 4 by if you will. Completely against its purpose, but funny. And it will have the big drop wanted by Francis
Seems like there's some potential for bikepacking/touring where I'm running a 32T front 11-46T rear but kind of missing a lot of that top end and might like some smaller jumps. What would put me off of this is serviceability and compatibility.
Wondering if this could become something the cyclocross pro’s will start to use in the future… being able to run virtual road sized front ring to go faster on the straights or tarmac sections.
And the aero gains from not having the front derailleur and little ring would be far better than the 365g added. Just look at wheels, heaver aero is better than lighter not aero. One question would be on wear and reliability though
The rohloff hub is a great peice of tech which I use on my Koga World Traveller. It also left you change gear at a standstill. Can the Classified hub change at a standstill?
Imagine you can conect it to your computer or an app like a Di2 and you can adjust the ratio in there. So when you are having a fairly flat ride you can equip a 1 - 0.7 and when you are climbing you can easily adjust it to a 1 - 0.3...
It has been done. Either Sachs or someone else did it. I saw one last year and took photos. Would be nice to know why it didn't succeed before and how whatever it was has been overcome this time. Servicing is a big obvious one.
Is it cool? Yes, definitely! Is it worth the money? Not for me. I don't have that amount of money to spend. When I do, I prob will upgrade by bike to electronic shifting first.
@francis: too much drop is not a good idea, because you want some overlap in your cassette. having small sprocket/small ring almost the same as big sprocket/big ring is already very annoying. with a drop even bigger than that, like drop at the front > range on the cassette, you'd end up with holes in your gear range, where the easiest gear in your big ring is way harder than the hardest gear in your easy ring. could be an idea for a video: how does a gravel crankset (46-30) with a road cassette (14-26) feel/work? is it the best of both worlds or a stupid idea?
combine it with a 2 x setup to get a 3rd ring this would totaly change for many many rider uphiill riding when you can have a 23 26 29 small ring with your standart 32-36 road cassette 46/33 34 cassette with classified you get 46 33 23 , so you avould a haevy 3by crank and mechanik fun you have with shifting
Actually 3-by would make sense again, but then you need full integration in the groupset (for up and down shifting) and something to monitor your gear.
I like the classified rear hub...I'm hoping they make a 130mm rim brake version, as it would make the ultimate set of bailout gear ratios especially if paired with a 2X drive train...
"You don't cross chaining" on a one by system two gears under and over the chain line you always cross chaining. Truly innovative: SACHS and later SRAM always had internal geared cassette rear hub. Lie upon lie upon lie...
On the weight comparison, it misses that you would typically use a clutched derailure on a 1x system. This would mean that a 2x system is lighter than this when everything is considered. But still may only be 100-200g.
@@ignaciosevil2157 but it is still the problem with change to different gearing. And the question why they, as far as I know, dosen't mention the mechanical versions in the clip.
IMHO, many of the problems associated with a front derailleur can be solved using a friction shifter. The infinite adjustment you get solves the alignment issues that can crop up, and you can get better shifts in some situations. Of course, a perfectly dialed in indexing setup is going to be better depending on what you are doing, but if you are road riding and not racing, the list of benefits an indexed setup has gets pretty small. I hope this tech gains a foothold and continues to improve. It looks pretty promising, especially if it had more ratio choices.
We’re running a 12-speed 11-34 cassette on our test bike (the largest on offer) & it’s 230g. The cassettes are pretty light as they’re a single machined piece (hence the cost) and are pretty heavily hollowed out so they fit onto the Powershift hub. Way more so than a standard road hub, so there’s just less material there.
1:21 "three or four rotations" what a load of shit, cant think of any groupset in the last 25 years were that statement applies, not even gen1 red with the titanium cage
The switch for the gear should honestly be a rocker type, then you can tell just by feeling what part is sticking out what gear you're in
Yeah, or click in click out. Lots of options to fix that.
@@johnnyt7067 yeah, a 3 way rocker would be ok, then it could support up to 3 gears for their hub if they ever do that
@@_Zane__ A 3-by would be great.
Justin may have liked that. Bigger ring for the flats but able to drop down for the hills.
Might be great for a hand bike
Tell these guys to start making some eMTB internal gear hubs. There is a pretty big hole in the market for sturdy, wide range IGHs that can handle hi power ebiles.

Keep the 2x mech up front, with the hub in back you would get ratios of 0.5 and 0.7 with a standard setup. But with this front chainrings of 53 and 44 also start to make sense.
Schlumpf has a very similar system to this, but it sits in the chainring instead, they have two different gearing ranges both are bigger than the classified hub. 1:1-1:6.5 and 1:1-1:2.5. So kinda what Cade was asking for.
you don't want to eliminate overlap. overlap is a good thing. Currently, when shifting at the front, you have to shift in the opposite direction by how much? 2, 3 gears? Imagine having a setup with no overlap at all... you'd have to shift right up to small:small, shift up the front and shift in the opposite direction the whole 11 gears. Now imagine how annoying that would be, even more so when you happen to be on a climb or a headwind situation, where the right gear at the moment happens to be between small:small and big:big... it would drive you nuts.
@@yurimow Yes, the gearing is extremely wide, but it's mostly meant for recumbents, where you might need gearing for 60-70kmh+, while still having very low gearing for climbing. Their 1:2.5 drive works quite well for this.
@@yurimow No you wouldn't. They aren't talking about overlap in range. They are talking about overlap in ratios making some gears redundant. There's no need to have that once you eliminate chain line considerations. Understanding when and how to shift the cassette alongside the internal hub is no different than with 2 chain rings
I ride the Classified Hub on Zipp 353s on my Wilier road bike and am very happy with it!
It's physically wired into the left DI2 shifter which eliminates the need for the sprint button that Classified provides. It was a little effort to perform the wiring but not terribly difficult. Rather than the toggling on or off that the sprint shifter provides, the DI2 integration allows one shifter button to put the hub in 1:1 mode (1) and the other shifter to put the hub into reduced (2) mode. That simplifies matters, but since the Hub integrates into my Karoo head unit I have a field on my screen which displays a 1 or 2 to indicate the state of the Hub mechanism. I installed a k-edge chain keeper on my 52t chainring to keep things in place. It's great technology, but better integration with Shimano or SRAM would be a real plus.
Could just keep the 2x and use this for mega range. Also I'm not sold on the chainline argument. I'd have thought you're more likely to have a more efficient chainline if you use 2x sensibly (ie not cross chaining) rather than one ring for all the cogs
I am with you on this. I use a rather large and heavy cassete 11-34 with a front 50-34 and get 1:1 ratio (105 R7000) that is not enough for steep hills with 10%+ grades on long rides (200km) and I would love to go for something more ultegra like with 11-28 rear and up a bit on from 52-36 crankset and 11-28 on the cassete with my climbing wheels with Classified hub ( not deep aero for flatter days ) and have a resulting range increased to 0.9 rather than 1 : 1….
Same, and I commented similarly before seeing your comment. I believe it was Friction Facts that confirmed this, that in use, 2x is always more efficient than 1x
@@parisneto 11-28 cogs on 52-36t chainring is more harder than 50-34/11-34

Wait...Did he REALLY just say one advantage is that "you're not cross-chaining"??? He can't be serious...ANY 1X setup creates a BIGGER cross-chaining problem than a 2x or 3x setup; that's just a plain fact. This may eliminate the need for a front derailleur, but (from a chainline perspective) you still have a 1x setup here. AND you're adding weight to the hub.
And to be honest, let's give this credit where it's due, but not over-inflate the innovation. This is really nothing more than an internal geared hub with Di2 shifting, with a cassette added. SRAM has effectively done this already (minus the eShifting).
Not drinking the kool-aid, sorry. "NEXT"
Fun fact, cross-chaining is not as inneficient as it's touted to be. In fact, big-big cross-chained is more efficient than equivalent small rings ratio, because of the shallower bends the chain has to make.
Agreed - and adding a planetary gearbox to the system isn't going to make it more efficient.
the efficiency is pissed away by friction generated by the outer plates as a result of the chainline
@@cosinus_square not enough to negate the shallower bends
I like how they compare their "perfect chain line" only to crossed chain on 2x systems, but they forget to mention that if you use your 2x properly chain line is much better than with 1x.
I'm a big fan of 1x myself, but this kind of data presenting is borderline with lying.
Agreed - if you’re in your lowest gear for example, so you have the reduction gear loss plus a worse chainline than a 2x, it’s definitely going to be less efficient. Is it enough to worry about? Dunno, but the fact that they effectively lie about it doesn’t inspire confidence.
@@cmmoll1and when you're on long and steep climb you want all the power to the wheels you can get lol
I would love to see someone using this with a front derailleur to create a 2 x 2 x 11.
I like this plan, but would remove cogs off the cassette to maximize chain efficiency by eliminating cross chaining, maybe a 2x2x6 which essentially would give you 2 additional gears over the 2x11 standard setup
You can use a Tiagra 3x left shifter which works fine with 11 speed everything to create a 3x2x11 or 3x2x12 for a comical 72 speed bike 😂
Just a reminder Shimano still makes XTR 3x Di2 front derailleur xD
It would be great if it actually had a lower difference ~12% between high and low. Then you could run a 11-40 and take the big jumps between gears and each one would have an intermediate 'classified' gear and because it shifts so instantly it doesn't matter unlike if you were shifting your front ring every gear shift. It gives the equivalent of a true 24 speed setup where there are no repeated gears and almost even spacing and you don't have to shift down the whole cassette when you shift from high to low ratio.
Exactly, same principle as retro 'half-step' gearing but then actually useable!
In my opinion, the issue with this system is that you'll need to get a number of such hubs in order to use different wheels. For example, on a gravel bike that you also use as a road bike. Or else, if you notice that you have a broken spoke just before your ride. This was my major criticism of the PowerTap rear wheel power meter.
True, but the hubshell itself is "only" 90.- bucks. So easy to set up a second or third wheelset.
Francis i think you’re spot on with the much lower ratio!
With full electronic sequential shifting you would then just need for one lever/button for upshift and the other for downshift. If each was configured for one ‘blip’ one gear, and longer pressure, shift till released, how cool would that be.
Try a Schlumpf Mountain Drive - 2.5x step down planetary gear.
Have a pair of classifieds wheels on my gravel bike and the were flawless all summer. There is one not talked about issue. Serviceability, on a standard set of hubs cartridge bearings can be replaced easily. When the non standard sized bearings need replaced in this hub, it needs to back to classified or the warranty is lost. In short the planetary gears are solid but cartridge bearings are cartridge bearings and will need replaced at some point. If that makes sense.
More of these product reviews please Francis. A top video. Very interesting product now with some quality wheels. Best regards Martin
Heavier and no mention of the watts wasted with a “planetary” gearing method. It’s usually 4% minimum. That’s a lot of wasted watts. I note their ambassadors are not racing anymore…
Back in the late 1990s I had a Bike Friday travel bike with a Sachs/SRAM 3x7 DualDrive system. That is, 3-speed internal hub combined with 7-speed cassette. I think Sturmey-Archer still makes a 3-speed hub with a freehub that will take 10-speed (and some 11-speed) cassettes. The big innovation here seems to be that Classified has added electronic shifting. And maybe made the hub lighter by limiting it to 2-speed.
How was it to ride?
@@Cade_Media It did the same job as a triple crankset, with less maintenance. The simplicity of a single chainring was very useful on the travel bike. It was heavy, though, and getting the shift cable set up exactly right was a bit fiddly. Plus the internally geared hubs are inherently less efficient since you are adding extra parts to the transmission - the planetary gears inside the hub are not 100% efficient!
@@Cade_Media Bad and complicated, heavy rear wheel and very hard to catch system how to use ..instinctivly. Thought that its cool but after using became clear not. Swedish bikes in 70s had similar hubs.
Now that I have finished watching the Cyclocross... This is bloody brilliant! I hope that the big manufacturers decide to pay a licence fee (or something similar) to use/replicate this....
With cyclocross i am waiting for the first one to use an rohloff with an belt.
They get so dirty in the first minutes that an can’t be performing at it’s peak level.
They’ll probably just make it themselves - Unless Classified have a watertight patent for an ‘internal hub gear that allows a cassette’
the business plan is to get bought by sram
that 363g weight difference is massive, especially considering you still need to add the weight of their special skewer and wireless shift module. that's pushing on 1 pound of weight added vs. only stripping 100-160g for a front mech plus 25g for an inner chainring. love the innovation but that is a heck of a penalty in not an ideal location to be carrying it handling wise.
Is it? What if you’re touring with a 30kg bike or have an e-bike?
@@Cade_Media fair points there but it is a cutting edge tech and something that should be desirable to roadies for several reasons. for touring and ebike duties it's ideal. i'd love to see a version that eschews all derailleurs.
@@Cade_Media If you are, you are way better of with a Rohloff E-14.
Very cool piece of tech. I immediately started fantasizing about a 3T Strada, Parcours Chrono + Classified hub, and Sram Red eTap AXS 1X groupset. Epic.
Let’s make it happen!
Interesting concept. I can see this mostly on gravel and mountain bikes. Turning a one by into a two by without a front derailleur to get ripped off. On the steep logging roads here in Oregon, it is easy to run out of gears, this would help a lot.
The price will come down if this gets popular.
Nice review, thanks.
I dunno about that. I think the roadies are more apt to still use 2x because they tend to pedal on the downhill, and they just tend to go faster. I'm not in the best shape, but a 1x with 32t up front and a 10-52t in the rear can get me up just about anything I want in my area in california- steep, punchy climbs. I dunno. Maybe it would be great though.
@@georgeforeman89 The beauty would be using a 12sp cassette with much smaller gaps than an Eagle 10-52t without loosing lower end range.
@@spencergiles72 sure, but I don't think many people care about smaller gaps. Hence the popularity of 1x. I'm sure some people would love it, but the classified system is SO expensive. Is having a better cadence (something mountain bikers don't generally care about) worth it? I guess that will be up to the individual people to decide.
If your worried about derailleurs getting ripped off you are way better off with a geared hub that gets rids of the rear derailleur, not the front one
A good point about it being 0.7 and 1 surely there will be a bunch of equivalent gear ratios in there just like you get with a normal 2 by. I guess it depends on the cassette used but a bigger jump in ratios would prevent some of the overlap. Would be a bit odd though going from the smallest cog in the "little ring" and having to sweep back to the biggest cog in the "big ring".
Evasive answering from the Classified guy on efficiency... most of us don't cross chain too frequently, how is the efficiency compared to a well maintained well lubed not cross chained configuration? I guess it has to have a bit more loss?
Perhaps you could take a look at the Schlumpf drive? A very similar system, but mounted on the chainring. They also have several gear ratios to choose from; 1:6.5, 1:2.5 and 2.5:1, all bigger ratios from the Classified.
It's cool tech and good to see that they are making first steps into the market, having wheel partners (including Mavic) is a good start. Nothing wrong with re-thinking something archaic as a front derailleur but I think, it'll stay a nichè product, just because it is expensive and most likely be paired with expensive components such as electronic groupsets and premium wheels in most builds.
For the efficiency thing, 2x is inherently more efficient due to chainline. When in the small ring, you're in larger cogs, and when you're in the large ring, you're in the smaller cogs. Extreme cross chainring is reduced.
Ideally, I'd like to see a cassette with 12sp spacing, but just 9 cogs or so, eliminating the smallest (hardest) gears. Put a bigger big ring to compensate, and use the hub for easier range. Lower friction due to actual better chainline, and lower friction from removal of inefficient cogs with few teeth.
"when you're in the large ring, you're in the smaller cogs"
The rationale is that you are much better off in the large ring, even when you're upshifting to larger cogs (more efficient riding large-large). Current 2x unfortunately will result in a bad chainline, and classified (rightly) claims their system enables you to keep a reasonable good chainline while riding large ring, large cog.
@@l.d.t.6327 in a traditional double chainring setup, there is an efficiency crossover around the second or third largest cog. You will have lower friction in the small ring and equivalent cog vs being in the large ring and second largest (and of course largest) cog. This is because at that point, chainline inefficiency in the large ring overrides lower efficiency from smaller gears. As a general rule, friction increases markedly when gears have fewer than 16 teeth. Above that, the difference in friction losses of different tooth counts is greatly reduced (but still present).
@@n0ch91c3sI see no everyone including myself riding in 52/53 in the front and up to 21 in the back. You simply don't go to the small ring unless you have to for longer or steeper climbs. There are plenty times you could do with a better chainline in the big ring. I had synchro shift for a while but ditched it.
How does re-charging work? Also probably worth mentioning the hub costs 1300 EUR on its own.
if you think about it, kit includes the cassette/shifter too and if you'll save money just by getting the 1x specific brifters/crankset and removing the FD, it's not bad. it's not cheap but definitely not overpriced.
@pipol champ 1400€ for a hub, truh axle, shifter and casette and you still need to build it into a wheelset. Can’t sell in the future, not officially integrated with sram or shimano and can’t service the hub yourself without voiding your warranty. Pretty hard sell for me at its current state.
They need to offer a whole drivetrain with shifters and hydraulic brakes. Team up with a chinese brand and target high margin market i.e. roadies and triathletes. Trickle down bikepacking/gravel/allroad bikes where this system could actually make a difference (ratio without overlap).
Is it still necessary to have a specific rear derailleur? Is it compatible with any 1x?
Been done before and never caught on, would like to see a different outcome this time...(See Sturmey Archer CS-RF3)
Has anyone mentioned the Sturmy Archer system? I've seen a bike with a triple on the front giving 42 gears, with so much overlapping...
I think this could be revolutionary if they would not try to use their own cassettes. Just let us use SRAM XD or microspline hubs and I would be all over this. Additionally, like you said, the genius of this would really shine if they lowered the gear ratio to 0.5 or 0.3. Imagine a 1x12 10-50t SRAM Eagle Mullet setup with one of these hubs setup for 0.3! It would be an absolute monster.
I also don't understand the chainline and chainring limitations... If I am using my existing 1x derailleur, then why can't I use any chainring size I want?
Yeah it would be an absolute monster of inefficiency at a big cost. LOL
The body size is much bigger then XDR or Microspline, thats why they cant use existing cassettes.
Keep the front mech and use this, get the 0.7x drop from the little ring. Super low gearing
I find it odd that this is perceived as an innovative product. As I have a 2012 Moulton TSR27 which is fitted with a SRAM Dual Drive, so I have a single chain ring (replaced with a narrow wide one for chain retention) and a 3 speed (not 2) rear hub. It works very well - yes it's old technology so has a cable, but my gear ratios are from 20 to 106 inches!
The dual drive goes back to the 20th century but was discontinued in 2017, I believe Sturmey Archer do an equivalent with a slightly lower ratio change of 33% rather than 36%.
Quite! I have one too and it works very well, don't have to worry about cross chaining and can shift while stationary. People can be so peculiar at times!
Looks very interesting. I would have thought having a small switch would be the better option rather than a button. You’d know which gear you were in immediately by feel alone. Love the idea of no lag though!
Now that is a brilliant suggestion
A 34 tooth Ultegra ring is 34 grams, the Ultegra front mech 90 grams - so, the weight difference is still hefty (for weenies, that is). Also, the blip and the battery/transmitter on the bars might add some grams as well.
Intriguing still, because fully encapsulated and thus out of the way of weather and wind.
Wondering how the abrasion inside the hub might change if used under high loads compared to "easing off".
Bummer that you need a thru-axle and thus, disc brakes for these, if I look at that correctly?
Maybe head units will be able to integrate with it. At then you could glance down at your head unit and see what gear you are in. It should be more than possible since SRAM and Shimano already does.
Man that elevator pitch needs some work. "Slightly more efficient went shifting in one direction"
How do you change hub recivers batteries?
Really would be good for belt drives. Cruising gear and climbing gear. And simple low weight alternative to other hubs and gearboxes
considering how fast Shimano removed di2 function from Hammerhead once SRAM bought them I don't expect much integration support for this on Shimano shifters.
Extremely well built and developed product however have they solved a problem? New gen front mechs are almost flawless and does anyone want to shift at up to 1000w? I get flicking through cogs at the back at high power but does anyone change front ring at high power? And obviously the price is mental
As always you provide an honest assessment of some cool cycling kit.
this may seem unnecessary for roadies but it is a HUGE upgrade for MTB especially for XC/enduro bikes, we can climb up punchy/techy/loose sections without needing to install a 50 tooth cassette AND STILL retain that much needed 1x setup. this would mean easier/balanced control on the rear end when doing berms/jumps/tailwhips whilst improving the RD shifting performance because of the smaller transition between the (now-smaller) easy cogs of the cassette. if they'll bring the cost down this would explode like dropper posts did.
Totally agree on the larger drop for gravel and touring and the like.
In a standard set up you are overlapping something like 6 gears. A little fiddling with bike gear calc shows me no overlap on an 11-28 comes at the equivalent of 53/22 chainrings.
I just don't get, why they are not marketing it to triathletes or time-trialists. It gives an aero advantage, weight is less important and the blip-style shifters are farely common there. Imagine a disc-wheel with this tech! A 58-14 and the option to go much lower at any climb.
Well cause it's less efficient and people spending that much money are usually conscious of that
@@jimsonjohnson3761 and the effectiveness and aerodynamic advantages of a single-speed drive, that you could still ride on a shorter track with climbs don't weigh that up?
I have a button in that position on my E-Bike for changing power level and I have adapted to using my pinkie to activate it when I'm on the hoods. No big deal.
Been waiting on this for a while. Still crazy money but the tech is very interesting. Like as EV cars comes in, the instant torque and no more "gear shifting" requirement is "a new thing". Very cool. This would be awesome on a MTB as well; lots of up/down shifting in those conditions.
Interesting technology but does a market for this really exist? Like all new tech, prices eventually come down but that is if they sell lots. Here in Canada I see that a high-end shop in Toronto is offering a wheelset with the hub for C$4150, or nearly C$4700 with tax. I have never had an issue with a front mech that would warrant getting rid of it and I appreciate its simplicity. Nicely done video, however.
Nice review! Will be watching don't think first gen is for me, but 2 gen I will look into.
Recently rode an enve melee with classified/sram and, have to say, the hub shifting was really cool and what a psych to see a 1x that rides like a 2x!
Great to see Dov again on your channel Francis, post 2022 Kona world champs week 👍.
Once Classified have integration from Shimano & Sram giants, its popularity is surely set to soar? Parcours are set to do well 👌
The real value in this is how it will influence frame design. A 1x bike with effective 2x utility can accommodate wider tires and a have sturdier bottom bracket housing. I wouldn't be surprised if Classified ends up being acquired by a firm with a long history of acquiring other companies, and a pioneer of 1x: SRAM
While I am excited about the premise of an effective 1x road design, this should be great for MTB and gravel too...rather than running the typical "pizza sized" cassette, you can apply a smaller cassette with tighter ratios. Tons of potential here.
Big advantage to this involves the tire clearance for the rear tire. Chainstay shape and size requires the consideration of many things. With a Classified system, you possibly gain tire clearance.
?
No front derailleur to worry about with wider tires
Presumably it is like Campy’s ultra shift down shift. But without the risk of dropping your chain when you drop down. So if you had the Campy button and this or maybe Di2 on the mega fast shift you can drop 1,2 or 3 ratios when you shift both at the same time. In the end though they need their own group set.
I have been following Classified for a while now - and I'm currently waiting to hear mor about their MTB lineup, as that should make it possible to work with my GRX812 on my gravel bike for much larger range on a 1x11 speed drivetrain.
Just use sram 1x12 eagle axs mix all the range, less gap between gears and much cheaper than the proprietary classified hub where you also can only fit their cassette. Shimano still makes the best Fishing reels though.
I'm pretty sure that their hub will be boost only since it's the absolute main standard on the market and therefor can't be used on gravel bikes with few exceptions like the salsa cutthroat.
I've run an 18t difference upfront before, with the 30t from grx600 and the 48t from grx810, and to be honest there is a point where there's too much front difference. Because changing 4 gears at once on the back to compensate for each front shift gets really old quite quickly. I think a 3x option would be far better.
A 3x option would be really cool
will be keeping a keen eye on this since it feels like they are only just scratching the surface of what this allows - similar to what some frames were doing when only 1x. chainstays and seat tubes can be reshaped. a wider spread with realiable shifting would also allow you to keep good gears for the flats while getting a lower gear for the long climbs...currently a chainring trade off
I Would love this on my mtb so i could have 2 ranges of closer ratios again but with the beauty of a 1-by system
I think it is very easy to fix the issue of now knowing what chainring you are in. It could be displayed on the head unit of most cycling computers, or a simple indicator (e-ink, LED) could be put on the bars, and this would be connected to the bar end plug.
A key advantage is that you can move the chainstays outboard, when combining with a T47 BB shell, and this is what will give you more tire clearance while at the same time removing the front chain ring. Finally, I think it is important to give free licenses to any manufacturers of cassettes. If they don't do that, there won't be incentives for companies to develop the complicated 3-D printing to reduce the costs of making the cassettes, and this thing won't take off on a large scale.
Can you run a classified hub with a double at the front to give you even more gears! Or maybe like an overdrive gear for sprinting? Or a gear that sits between a small ring and a big ring?
So it enables cross chaining and has more moving parts (more drag) yet the guy from classified says in the video that somehow this hub changes physics. Not sure about that mate a "traditional" drive train is far more efficient. Still an interesting concept. Also why are we adding more weight to wheels.
2:34 "What's the problem that it solves ?" => Proceeds to explain it not solving a single problem.
Classified should done politics before cycling
This would be best on an emb with the LCD display to show which gear you are in, would also extend the battery life allowing you to switch to the larger gear for flat section enabling you to go faster to save the battery assistance kicking in
thank you for the video Cade media
1:21 3 or 4 rotations for a gear change? How bad were his front derailleurs set up? lol
Feeling Dovs helmet too !
It really is an honest view, thank you and all the best for this new chapter.
I recently test rode a Pearson bike with a Classified set up
Positives:
+ instant gear change
+ reliable gear change
Negatives:
- very high cost
- blip button is not in an ergonomic place
- you still get the same overlapping gear ratios as a 2x
- adds weight to a 1x system
- is a very high tech solution to the solve the same problem as a front mech has done for decades
It’s basically a rich persons toy and way up the list of expensive unnecessary upgrades
I assume Classified are just looking to get bought by Sram or Shimano
Fair assesment there!
The thing that would worry me is front mechs are pretty simple mechanically speaking, but a hub that's got some clever gearing tech going on inside it...what happens if it breaks? how do you maintain it longterm ?. Sturmer Archer hubs were never much fun to fix.
Baloney. SA Parts are ALL available, unlike complicated Shitmano crap.SA hubs can be rebuilt blindfolded almost.
I have a 2017 X-RD3 and 2012 XL-RD5w. Although the 5w did have a machining glitch causing the 2 key nubs to catch on the edge of the hole going into the planet part. I filed and grinded mine with a pen diamond bit engraver. Goes like a charm now. My tour bike is 120 lbs loaded. My Rohloff14 has ZERO problem keeping up with deFaileur bikes at half the weight. LOL.
@GordoGambler ever tried to fix a Sturmey Archer hub? If not you don't know what your talking about, availability of parts is not the problem
Great video Francis. Love the tech, but I’m not sure the value proposition is really clear. If I’m already having to shift manually, and think about it, the speed of the shift doesn’t really mean much to me. It is elegant tech, just fixing a problem that might not exist?
This hub and a greater range would be amazing for ultra endurance cyclists, bike touring, and bikepacking!
I wouldn't go too far with this until it prove it's reliability.
I was thinking it might be handy when you have a 50kg bike!
Yeah, but if you've got this kind of money to spend and wanted a IGH you'd get rid of the derailleur altogether and bung a rohloff hub in, like many cycle tourists do. Or sacrifice a bit of range and quality and use a Shimano Alfine 11.
Ah, helpful insights.
Def need to feel this versus my IGH. Now the scour the web for Classified vs electronic IGH comparisons.
Lots of potential in this system. The opportunities for an all-road option (say a road big ring and cassette but a 0.6 ratio) and a TT option (so you can use your standard TT bike on sporting courses) look especially interesting. If the tech matures, and they can drive the cost down and eliminate some minor niggles (can't see what 'ring' you're in, no SRAM integration, etc), I'd be very interested.
Amongst Others must be very rich, that guy's an investor in nearly anything at this point!
Jokes aside, how often do you shift between front chain rings under load?
For rear shifting a derailleur is significantly more efficient than a hub, how is it different here? And if they managed to solve the efficiency issue, is it an option to make a rear hub then?
I would love to see someone set it up with front derailleur as well, a 4 by if you will. Completely against its purpose, but funny. And it will have the big drop wanted by Francis
i rode it on a cyclocross bike - unbelievable fast shifting and very smooth.
Step up would be a nice option to ride your MTB to the trailhead. Small chainring that shifts to a 1.7x ratio for fast riding
Even if this might not be for every one, I love that we’re seeing something new in drivetrain tech other than adding or removing gears.
Could be great for the single speed tribe. One for the flat , one for the hills.
Seems like there's some potential for bikepacking/touring where I'm running a 32T front 11-46T rear but kind of missing a lot of that top end and might like some smaller jumps. What would put me off of this is serviceability and compatibility.
Love that hub,, now I can have a 4x road bike. Just add a front mech while having that hub.😃
Wondering if this could become something the cyclocross pro’s will start to use in the future… being able to run virtual road sized front ring to go faster on the straights or tarmac sections.
And the aero gains from not having the front derailleur and little ring would be far better than the 365g added. Just look at wheels, heaver aero is better than lighter not aero. One question would be on wear and reliability though
The rohloff hub is a great peice of tech which I use on my Koga World Traveller. It also left you change gear at a standstill. Can the Classified hub change at a standstill?
Imagine you can conect it to your computer or an app like a Di2 and you can adjust the ratio in there. So when you are having a fairly flat ride you can equip a 1 - 0.7 and when you are climbing you can easily adjust it to a 1 - 0.3...
It has been done. Either Sachs or someone else did it. I saw one last year and took photos.
Would be nice to know why it didn't succeed before and how whatever it was has been overcome this time. Servicing is a big obvious one.
Is it cool? Yes, definitely!
Is it worth the money? Not for me. I don't have that amount of money to spend. When I do, I prob will upgrade by bike to electronic shifting first.
@francis: too much drop is not a good idea, because you want some overlap in your cassette. having small sprocket/small ring almost the same as big sprocket/big ring is already very annoying. with a drop even bigger than that, like drop at the front > range on the cassette, you'd end up with holes in your gear range, where the easiest gear in your big ring is way harder than the hardest gear in your easy ring. could be an idea for a video: how does a gravel crankset (46-30) with a road cassette (14-26) feel/work? is it the best of both worlds or a stupid idea?
combine it with a 2 x setup to get a 3rd ring this would totaly change for many many rider uphiill riding when you can have a 23 26 29 small ring with your standart 32-36 road cassette
46/33 34 cassette with classified you get 46 33 23 , so you avould a haevy 3by crank and mechanik fun you have with shifting
Actually 3-by would make sense again, but then you need full integration in the groupset (for up and down shifting) and something to monitor your gear.
I like the classified rear hub...I'm hoping they make a 130mm rim brake version, as it would make the ultimate set of bailout gear ratios especially if paired with a 2X drive train...
If it integrates with Di2 and displays the gear data on your headunit I think I’m sold. Imagine running it on the Di2 syncro shift mode!
"You don't cross chaining" on a one by system two gears under and over the chain line you always cross chaining. Truly innovative: SACHS and later SRAM always had internal geared cassette rear hub. Lie upon lie upon lie...
On the weight comparison, it misses that you would typically use a clutched derailure on a 1x system. This would mean that a 2x system is lighter than this when everything is considered. But still may only be 100-200g.
I want my gears to be mechanical and I am thinking of changing to chainrings with smaller difference. None of these are possible with classified.
There are mechanical classified hubs. Read the info again
@@ignaciosevil2157 but it is still the problem with change to different gearing.
And the question why they, as far as I know, dosen't mention the mechanical versions in the clip.
@@MarkusFolkesson hard to understand, I think with classified I could increase mytop speed capacity on the bike.
Yes, would be great if you could have the second gear ratio to just extend from biggest ring in normal mode, i.e. not overlapping the gear ratios
I have a Sram 3x7 real hub and I really love the concept.
Oh cool classified
IMHO, many of the problems associated with a front derailleur can be solved using a friction shifter. The infinite adjustment you get solves the alignment issues that can crop up, and you can get better shifts in some situations. Of course, a perfectly dialed in indexing setup is going to be better depending on what you are doing, but if you are road riding and not racing, the list of benefits an indexed setup has gets pretty small.
I hope this tech gains a foothold and continues to improve. It looks pretty promising, especially if it had more ratio choices.
Most front shifters are friction.
Finally someone weighed the bloody hub by itself THANK YOU!! lol how much does their cassette weigh?
I’ll see if dov will weight it for you
We’re running a 12-speed 11-34 cassette on our test bike (the largest on offer) & it’s 230g. The cassettes are pretty light as they’re a single machined piece (hence the cost) and are pretty heavily hollowed out so they fit onto the Powershift hub. Way more so than a standard road hub, so there’s just less material there.
@@Cade_Media thank you!
@@ParcoursDov Also thank you and awesome.
1:21 "three or four rotations" what a load of shit, cant think of any groupset in the last 25 years were that statement applies, not even gen1 red with the titanium cage
