I'd be more interested to see a longevity test of a bike like this. I'd would love to see the cost of keeping something this fragile on the road over a period of a couple of years.
A guy in Germany has/had a bike like that ~10 years ago and rode it a couple hundred miles per week for years. However…. IIRC he was like 60kg and had great road quality and didn’t have huge hills to mash up.
I would imagine that the carbon chainrings and jockey wheels would need replacing every few hundred miles. And brake pad replacement would be an awkward job.
I feel like are missing the point, If you’re asking about durability. I watch because it’s cool to see but I’d never own this, even if I could. We all know strong - light - cheap, pick 2.
@@samgreen5622 I’m more intrigued as to how much it costs to keep a super light bike on the road. It’s something the bike industry never actually wants us to know.
ive added 15kg lead to my bike😂 700c/23c alloy specialized , once your up to speed you carry far more coast momentum (i'm thin build 50kg ) and can just pedal a little bit every 5secs and get around for low watts it seems , im adding more weight soon i can probably add 50kg and will only be the equivalent of a 16st lad in total including me . I'm verrrrry lazy and more weight genuinely feels less effort to maintain speed .

"you can make quite a big saving when it comes to bearings". I will never understand weight weenies, but I really love the length people are willing to go to to reach this ultimate goal
this case was extreme, was a business trying to make publicity, on the road bike ambient, yes, the weight is importante, but, only if you're racing, or reaching goals or training hard, there's a lot of guys that weights 100 kg and his bike 9, and they chance everything to make it lighter without looking themselves, is a less is better conception, i'm saving for a bh, i was between the rs1 and the aerolight, which is heavier, but faster, there is not the point 100grs less, the aero benefict is stronger, always got to see the whole image
I think he's not allowed because it's a customers bike. But it would be a challenging ride anyway. It's a 58, and the seatpost and saddle are fixed. So it's probably just to big for him.
10:50 the cage has not been swapped out on the front derailleur. That's a standard Record cage from the early 2000s. The plastic chain bumper has been taken out tho'.
Off topic but have just finished Ollie's rouvy challenge. I did the 3 climbs in a week and thought I was going to die on the last one. Ollie doing them 3 in a row is amazing, chapeau!!
I love how stoked he seemed when feeling the lightness of the wheel getting up to speed so quick and easily! That’s his utmost genuine reaction ever as the bike/science nerd he is at heart!
Carbon chainrings and pulleys are not designed to last at all. They are pretty to look at and are light, but you'll need a subscription to the manufacturer to keep replacements coming.
If you knew anything about AeroLite pedals, you'd know that the cleat snaps down onto the roller bearing supported barrel (black piece_ and to release, you tilt your foot outwards (away from the bike) instead of twisting at your heel. I owned some in the early 90's ... super smooth, but walking in cycling shoes with those cleats is SUPER DUCK walk!
I built a weight weenie bike similar to this a few years ago, down to 9.6 lbs. After a while of riding I found that the drivetrain was not as responsive and reliable, so I took off the fibre-lyte chainrings and put on Di2 shifting. Now it's much more of a daily driver, up to 10.7 lbs. It's still pretty scary going down long steep descents, so better to use another bike for that. The aerolite pedals are very good and efficient and easy to use, but if you are sprinting hard especially uphill and you move your knees outward, the foot can come out of the pedal since this is the way to get them out. It's a knee-in and knee-out to clip in and out (not sliding in and out as Ollie mentioned).
I built a Klein Attitude in the 90s that weighed around 7 kilos. My ex girlfriend stole it and later sold it for £300. Around one thirtieth of its value. Three decades later I'm still pissed off about it.
Reminds me of Art Stump in Santa Monica CA in the early 1970s. His black-chromed custom steel frame and meticulously drilled and pared components kept the weight around 19 lbs / 8.8kg, which was damn good in those days.
Regarding the pedals, I am sorry to tell you that you are wrong, you do not slide the shoe into the pedals, but yourather push down your foot into the pedal applying pressure on the edge first then it will snap on! Excellent review by the way!
The cleat and hardware are light - mainly plastic. They work as the top commenter states. The resistance (how difficult to get in-out) was tuned by screw mounts of the cleats on the shoes. Hard to describe fully so I haven't done well here. These first appeared in the 1980s.
Heck Yes.... Get Andrew Feather on that bike. One:: It suits his name and two: it would be epic to see him take on an epic climb and see what he sets the KOM by.
I had aerolights on a tri bike in the ‘80s. You just click in and twist off. The cleats are bulky and you must lengthen your seat post over an inch and adjust everything to compensate. Lean angle is incredible too. Didn’t know they were still made.
I actually think the downtube shifter is quite a neat idea. You've still got a reasonable range of gears available out of the saddle; I'm pretty sure they looked at how often you change the front mech compared to the rear and decided to save a couple of hundred grams instead...
8:19 Dear Dr. Bridgewood, how fast it accelerate after you do one turn has nothing to do with the weight of the wheel, but rather only how fast you spin the crankarm. Imagine you have a muscular weightlifter arm, you'll be easily accelerate an steel wheel that much with one turn
i like very much, its amazing that all pins in the chain seem to be hollow, very nice machine, i totally agree about the weight sweet spot at apx 4.6 to 4.8 to give a more sturdy feel for decending, yes would love to watch andrew tackel a notorious climb on it.
I have the original Cervelo R5 California frame, sub 700 grams, as well as the last R California frameset, sub 650 grams ... I did not build the bikes to be the lightest bikes possible, but I did load them up with the best components, in the most beautiful build look. They are below 5kg, so less than 11 lbs ... I tend to agree, a bike can be too light. When I ride my California's, I feel like I am piloting an F16! ... it is fun tough, to see how a shop makes the lightest bikes possible ... why not! ... Ok GCN, let's see a rider on it!!!
I actually looked at that bike in person. It is was more amazing than this video can show. BTW, the bike was at Fair Wheel Bikes warehouse on Park Avenue in Tucson Arizona. BTW, this bike was covered by Bicycling magazine and was listed as 6.8 pounds vice the UCI limit of 6.8 Kg. I didn't see mention of the price, but when it was built it cost in excess of 30k USD for all the work and parts.
These videos are cool for me because I'm from Tucson. Given you all were down there making these videos Im sure you checked out Mt Lemmon (or as i jokingly call it: col de Sonmex). It would be epic if you did some kind of epic climb video in Tucson. Have andrew feather fly in and ride with Lionel Sanders and Sam Long who live down there and have battled over that KOM. Heres one for you....3 man relay up lemmon. Just to see how fast they could do it as a team. Or a 3 man GCN team against one of those guys. Thanks for the great videos and for coming to the states!
Some obvious additional weight savings: Shave down the brake pads (you only need enough to last a couple of rides). Ditto for the tyres (why lug around all that extra rubber?) The saddle nose looks like it could be a few mils shorter. And the branding only needs to be the outline of the letters.
Feather riding a feather up a hill, ohh yes please, would love to see that. Be interesting how much quicker he would be compared to his normal bike up the same hill 👍
I’m around 88 kg and I would be very uncomfortable riding this worrying about it just shattering. That said, it’s incredible what is possible when it comes to weight savings.
@@vonderponey3596 I'm 105kg +/- and I actually have a couple of these components on my bike: the THM cranks and I currently have a 30T fibre lyte little chainring on since I could only get the aluminum KCNC down to 32T. (mountains!) As for this build overall I'd take a hard pass. I'll pay for lightness, but not for inferior functionality. (Big carbon chainring chipped a tooth on me.)
You can build a sub 6.8 kg rim brake bike without even trying. No special light weight components, no compromises on safety or structural integrity, and compared to modern bikes at a fraction of the price. The old paradigm was a harmonious, refined set of complimentary components that when combined thoughtfully produced a bike that was much more than the sum of its parts. Road bikes were better before disk brakes.
I'd love to see a sub-4 kg bike race contest. Like a bunch of people build bikes as light as possible and then compete on them. Similar to how Red Bull has their wild challenges like the hang gliders and downhill carts.
@@dan43544911 the point isn't to see who's the best cyclist, it's to see who can build something that can handle the race. Look up Red Bull's hang glider contests or downhill carts contests. They're a blast.
This is an old bike that could be made lighter. You could even get those cable housings in Carbon at 1 point. Fairwheel bikes were pioneers back in the day on the weight weenies site. I once built a 4.6 kg Scott CR1 LTD using a lot of the same components. Light as a feather but not the best to ride for any sort of distance. But, I would use the Clavicula cranks & Tune hubs on any bike. Top quality stuff.
Super interesting build, but as you pointed out it's just suitable for hill climbing. Sadly the chainrings from Fibre-Lyte will be the first thing to be gone, carbon fibre tooth against titanium-steel chain... not going very far before abrasion took over
I'm curious how long it took to tune/source all of the parts for the build. It takes a lot of time to grind away stuff and have it look good in the end. Also, cost of course, not to critique, just curious how much it took to get it to that weight. Awesome build!
That's what I was thinking about, or at least a single speed. Can it break the 3 kg wall taking off shifters, a brake (in case of the fixie) and so on?
Fixies and front brakes are a bad mix. If you do an emergency braking with the front brake, the momentum from the back wheel will make the bike buck and send you flying head-first into what you are braking from. That's simple physics. I rode a fixi for apr. 20,000 miles as a messenger three winters a couple of decades ago (single-speed freewheel in the summer half of the year) and I never used a front brake. In stead, I learned to brake and manoeuvre properly with the rear wheel.
does anybody remember the "Gunther Mai" bike, assembled by the same guys from Fairwheel Cycles? Twelve years ago, this project creates a 2,7 kg bike!!! THIS IS THE LIGHTEST. You can easily find photos and info on line.
That's the standard issue carbon fiber cage on the Record derailleur. They've been carbon on Record since around 2005. Looks funky, is very light, but unfortunately also a lot less durable than the aluminium cage on Chorus... Other than that, I liked how Ollie goes on and on about the acceleration of the rear wheel. However, what REALLY is unusual here is how insanely many engagement points there are on that prototype Tune hub.
@@space.youtube I recently broke one from about 2016, and I can guarantee that it's just carbon fiber. Maybe some model years were carbon-wrapped steel.
@@Antti5 The FD on this bike is badged "Titanium" which dates it to circa '04-'06, so the 2016 iteration is almost irrelevant. It's from the late square taper carbon crank, black brake caliper era. I do not have this Record 10v groupset, but I do have earlier and later Record 10v groupsets. So I checked what I have. The '07-'08 Record "UT Ultra Torque/QS Quick Shift" era FD has a heat treated alloy cage with the outer plate reinforced by a carbon layer. The FD chain interface is still metal on metal, both shifting up onto the big ring, and down. Campagnolo may have utilised a full carbon outer plates in '04-'06 Record, but for whatever reason (durability, stiffness perhaps) it didn't in the UT/QS 10v Record era. It seems odd to me that they'd take an apparent 'step back' though? Maybe they had issues that were later resolved in time for the 11v era? Or maybe the '04-'06 Record 'Titanium' FDs were in fact also alloy with carbon reinforcement?
Am I the only one thinking it's really weird how rim brakes in 2024 have such limited options, like for tire/wheel widths etc? It's like the industry is really pushing to phase them out completely for no reason but to push heavier, more expensive disc brakes that are harder to repair
i imagine walking this bike down some stairs with my chest out, put it down on the road and confidently mount the bike, with one pedal stroke i accelerate to 30k get two punctures and then can’t brake
Keen eyed among you will recognize the the brake / shifter hoods are original Sram Red 10 speed, heavily modified and victim of the dremel by Fairwheel. Us old farts will also recognize the downtube shifter to save weight, he who's name will not be spoken (LA) did this in the 2000 TDF. Don't forget to cut the seat post and all bolts to be as short as possible yet still be functional. The seat post only needs ot extend below the junction between the top tube and seat stays. Bottle cage bolts typically only need to be 10MM long. Keep unique content coming GCN, anyone with deep pockets can buy a pro tour level bike, not everyone has the vision or creativity to build a unique bicycle.
Outstanding video. Yes, I would be totally excited to follow a video of yours where Feather climbs a challenging hill with a lightweight bike like this, perhaps comparing the performance (and his impressions) with using a current, modern bike like the one the Pros use for TdF climbs. Btw, I think the climbing times will be in favor of the lighter bike, even though every race (except for time trials like the one on the last stage of the Giro d'Italia 2023) also features as much downhill and especially flat...
Weird combination. A 2x which you dont need for hill climbs, but brake levers which will snap the first time you have any serious braking on road. Where are you meant to ride this?
Ride it? Nah, it's just to look amazing hanging on a scale. Screwball stuff like this was all the rage before the UCI minimum weight rule came into force.....just like Spinaci bars... remember those..coolest things ever...until they were banned?
Very nice video. I've just got one small correction: I've used several 11-23, and one 11-27 10S Recon cassettes. They are not anodised. Instead, they are ceramic plated. This extremely smooth ceramic layer is not wearing at all, unless your chain is skipping hard on the cassette, damaging parts of it. I've had anodised KCNC as well, made of same alloy, and it was not lasting long, due to abrasion. This ceramic layer is so hard, that cassette is lasting as long as the steel one rather than any anodised aluminium one. I'm familiar with machining metals, including Al 7075. Also I'm not very powerful rider, though usualy riding long slopes - so I can only guess, Recon would be finished much faster being riden by more powerful rider by denting Al 7075 teeth rather than normal abrasion wear, because even hardest aluminium alloy is much softer than hardened steel - you can hit a sample with the hammer, and it's dented easily.
"We could use your support" was a worrisome comment. ☹️ That said, I'll always be a fan of Red 10. It was way ahead of its time and is still an impressive mechanical gruppo. I loved the bike i had it on.
I dont know a thing about road bikes but in downhill bikes i learned that when you go too far in weight savings parts starts to break or bent. It would be interesting to see a durability test in these ultra light weight builts, in a real world without a super light rider in a ultra smooth road.
We are with you if we can ever get the US congress off their butts long enough to send you money! Probably training your pilots here right now. Praying for you guys! 😢
Nice video! I seem to remember one of the mountain biking journalists may be Steve Worland or Chipps building the lightest possible mountain bike. The only conclusion I remember was that it rode like a pig...
Well, every component has been compromised in some way to save the last bit of weight. It's stupid, shaving off those final 3 kg off a bike is not worth it at all.
@@glossymouse7712 lol the same can be said for shaving a bike down to 7kg. If you have trouble riding a 10kg bike fast up inclines it's a "you" problem
@@kennethg9277 I agree, when I started cycling I couldn't go up inclines at all cause "my bike was too heavy" or something. 2 months later I was going up steep inclines in the top gear.
The freehub is the best thing about this monstrosity of a bike. I can't imagine being such a weight weenie that I must own the highest possible everything; train harder and get fitter if you want your bike to feel lighter. My bike weighs around 16.5 lbs with nothing on it and I don't even feel it because I weight train daily from November-April, ride the trainer from January-whenever the weather breaks (March/April), and by the time I'm back on the road I've gotten so much stronger that my bike feels like it weighs nothing even when it's loaded up
Watching this makes me wanna go to my basement and start playing with carbon fiber, build a bike like that one! Ollie you rule! Whoever's idea it was to build this bike and make it happen, you are awsome!

@@Gicus94 disc brakes look masculine? er ok. Carry on, whatever it takes.
Cyclist raving about rim brakes remind me hipsters and their vinyl records
@@ssensselExactly. The same people who wax poetically about their old-school RIM cellphones that were “better.”
Some obvious additional weight savings:
Shave down the brake pads (you only need enough to last a couple of rides).
Ditto for the tyres (why lug around all that extra rubber?)
The saddle nose looks like it could be a few mils shorter.
And the branding only needs to be the outline of the letters.
Feather riding a feather up a hill, ohh yes please, would love to see that. Be interesting how much quicker he would be compared to his normal bike up the same hill 👍
I like that it's also very good looking bike. And that's the most important thing ;)
I’m around 88 kg and I would be very uncomfortable riding this worrying about it just shattering. That said, it’s incredible what is possible when it comes to weight savings.
I’m 64 kg and I wouldn’t feel comfortable riding this down my driveway! 😀 I do like that it exists though, just not for me.
One tiny gust of wind and that would be it!.
I'm 100kg and obviously I don't ride bikes 😅 Well motorcycles, and my old Colnago Sprint
The rider weight still makes the biggest difference - That said, a bike like this will make you fly up hill 💨
@@vonderponey3596 I'm 105kg +/- and I actually have a couple of these components on my bike: the THM cranks and I currently have a 30T fibre lyte little chainring on since I could only get the aluminum KCNC down to 32T. (mountains!) As for this build overall I'd take a hard pass. I'll pay for lightness, but not for inferior functionality. (Big carbon chainring chipped a tooth on me.)
I'm tired of mountain bikes getting heavier all the time so I'm happy anyone is talking about light bikes
It's not a cotton bar tabe, it's an automotive electrical harness wrap XD
Super interesting O.Keep up the excellent vids.Thanks mate
You can build a sub 6.8 kg rim brake bike without even trying. No special light weight components, no compromises on safety or structural integrity, and compared to modern bikes at a fraction of the price. The old paradigm was a harmonious, refined set of complimentary components that when combined thoughtfully produced a bike that was much more than the sum of its parts.
Road bikes were better before disk brakes.
They were far worse. Thank God rim brakes are a dying relic of the past.
I'll second that emotion!
I love my discs.
Incredible, how cool it is that these people can work on such a level of detail!
True cycling nerd territory for sure 👀
I'd love to see a series with a track sprinter trying to snap that thing 😂
Brad the Body builder.
Wouldn’t need a series, just .25 of a very short video clipette.
They need to get Quadzilla on the channel. Look him up, he is insane
What do you mean trying? It would break if someone who weights 80 kg try to ride it
@@larshaukenfrers is he not a rugby player?
"Just so HEAVILY modified" -- Ollie being unintentionally ironic all of a sudden!
It looks beautiful too and I love the rim brakes! 👍🏼💜🇬🇧
Deer gawd thats awesome Ollie and yes I would love to see Andrew Feather making his way up an epic climb riding the Alpha AC.
The acceleration of the back wheel is given by how quickly you manage to do your one rev
What?
I'm not a "roady" at all, I have 0 interest on road bikes, but this is very interesting as an engineering exercise.
I'd love to see a sub-4 kg bike race contest. Like a bunch of people build bikes as light as possible and then compete on them. Similar to how Red Bull has their wild challenges like the hang gliders and downhill carts.
Great idea!
A good cycler in a 6.5 kg bike would crush ever moderate biker on a 3 kg bike so I don't see the point.
@@dan43544911 the point isn't to see who's the best cyclist, it's to see who can build something that can handle the race. Look up Red Bull's hang glider contests or downhill carts contests. They're a blast.
I once made a commuter V brake 27 speed at 10 kg.
I thought I was a legend. 😂
It was lovely though.
If you want to get the that sweet spot 4.6kg, just add a full bottle and you're done :D
This is perfect for some DH ride or even RB Rampage show.
Diminishing returns has entered the chat.
Loving the Withnail reference
This is an old bike that could be made lighter. You could even get those cable housings in Carbon at 1 point. Fairwheel bikes were pioneers back in the day on the weight weenies site. I once built a 4.6 kg Scott CR1 LTD using a lot of the same components. Light as a feather but not the best to ride for any sort of distance. But, I would use the Clavicula cranks & Tune hubs on any bike. Top quality stuff.
Plenty of us at GCN used to waste/invest many hours on the weight-weenies forum back in those days!
This is by far the best sounding hub I've ever heard.
Super interesting build, but as you pointed out it's just suitable for hill climbing.
Sadly the chainrings from Fibre-Lyte will be the first thing to be gone, carbon fibre tooth against titanium-steel chain... not going very far before abrasion took over
... before abrasion takes* over.
The campagnolo record front derailleur is stock, that carbon cage comes stock with the 10 speed campagnolo record titanium groupset.
I'm curious how long it took to tune/source all of the parts for the build. It takes a lot of time to grind away stuff and have it look good in the end. Also, cost of course, not to critique, just curious how much it took to get it to that weight. Awesome build!
A build like this will take a while to really dial in 👌
Perfect Paris-Roubaix bike :)
Don't put a bottle of water into it!!!
Super interesting video. Would love to know how long it would last on a British road with pot holes
Would love a road fixie superlight weight build. ( 50/18 165mm cranks, front brake etc).
Something to think about.
That's what I was thinking about, or at least a single speed. Can it break the 3 kg wall taking off shifters, a brake (in case of the fixie) and so on?
@@claudiofiero8523 Thinking about this, I can find pos 500g. I'm sure it could be done
I built a fixed gear with a custom frame currently 3.8kg but could be made lighter if i had infinite money
Fixies and front brakes are a bad mix. If you do an emergency braking with the front brake, the momentum from the back wheel will make the bike buck and send you flying head-first into what you are braking from. That's simple physics.
I rode a fixi for apr. 20,000 miles as a messenger three winters a couple of decades ago (single-speed freewheel in the summer half of the year) and I never used a front brake. In stead, I learned to brake and manoeuvre properly with the rear wheel.
does anybody remember the "Gunther Mai" bike, assembled by the same guys from Fairwheel Cycles? Twelve years ago, this project creates a 2,7 kg bike!!! THIS IS THE LIGHTEST. You can easily find photos and info on line.
That's the standard issue carbon fiber cage on the Record derailleur. They've been carbon on Record since around 2005. Looks funky, is very light, but unfortunately also a lot less durable than the aluminium cage on Chorus...
Other than that, I liked how Ollie goes on and on about the acceleration of the rear wheel. However, what REALLY is unusual here is how insanely many engagement points there are on that prototype Tune hub.
I want that hub!!
The Campag Record FD cage is steel with an outer carbon overlay.
@@space.youtube I recently broke one from about 2016, and I can guarantee that it's just carbon fiber. Maybe some model years were carbon-wrapped steel.
@@Antti5 The FD on this bike is badged "Titanium" which dates it to circa '04-'06, so the 2016 iteration is almost irrelevant. It's from the late square taper carbon crank, black brake caliper era. I do not have this Record 10v groupset, but I do have earlier and later Record 10v groupsets. So I checked what I have.
The '07-'08 Record "UT Ultra Torque/QS Quick Shift" era FD has a heat treated alloy cage with the outer plate reinforced by a carbon layer. The FD chain interface is still metal on metal, both shifting up onto the big ring, and down.
Campagnolo may have utilised a full carbon outer plates in '04-'06 Record, but for whatever reason (durability, stiffness perhaps) it didn't in the UT/QS 10v Record era. It seems odd to me that they'd take an apparent 'step back' though? Maybe they had issues that were later resolved in time for the 11v era? Or maybe the '04-'06 Record 'Titanium' FDs were in fact also alloy with carbon reinforcement?
If the Tune hub is anything to go by, we need to get a look at some more prototype components!
The cage of the Campagnolo Record front derailleur has actually not been swapped. It's carbon stock already
Am I the only one thinking it's really weird how rim brakes in 2024 have such limited options, like for tire/wheel widths etc? It's like the industry is really pushing to phase them out completely for no reason but to push heavier, more expensive disc brakes that are harder to repair
only Ollie makes quality video nowadays
i imagine walking this bike down some stairs with my chest out, put it down on the road and confidently mount the bike, with one pedal stroke i accelerate to 30k get two punctures and then can’t brake
Keen eyed among you will recognize the the brake / shifter hoods are original Sram Red 10 speed, heavily modified and victim of the dremel by Fairwheel. Us old farts will also recognize the downtube shifter to save weight, he who's name will not be spoken (LA) did this in the 2000 TDF. Don't forget to cut the seat post and all bolts to be as short as possible yet still be functional. The seat post only needs ot extend below the junction between the top tube and seat stays. Bottle cage bolts typically only need to be 10MM long.
Keep unique content coming GCN, anyone with deep pockets can buy a pro tour level bike, not everyone has the vision or creativity to build a unique bicycle.
Outstanding video. Yes, I would be totally excited to follow a video of yours where Feather climbs a challenging hill with a lightweight bike like this, perhaps comparing the performance (and his impressions) with using a current, modern bike like the one the Pros use for TdF climbs. Btw, I think the climbing times will be in favor of the lighter bike, even though every race (except for time trials like the one on the last stage of the Giro d'Italia 2023) also features as much downhill and especially flat...
I can't believe they didn't let you ride it! Gee! Definitely need to see Feather go for KOMs on this!
Weird combination. A 2x which you dont need for hill climbs, but brake levers which will snap the first time you have any serious braking on road.
Where are you meant to ride this?
Ride it? Nah, it's just to look amazing hanging on a scale. Screwball stuff like this was all the rage before the UCI minimum weight rule came into force.....just like Spinaci bars... remember those..coolest things ever...until they were banned?
Very nice video. I've just got one small correction: I've used several 11-23, and one 11-27 10S Recon cassettes. They are not anodised. Instead, they are ceramic plated. This extremely smooth ceramic layer is not wearing at all, unless your chain is skipping hard on the cassette, damaging parts of it. I've had anodised KCNC as well, made of same alloy, and it was not lasting long, due to abrasion. This ceramic layer is so hard, that cassette is lasting as long as the steel one rather than any anodised aluminium one. I'm familiar with machining metals, including Al 7075. Also I'm not very powerful rider, though usualy riding long slopes - so I can only guess, Recon would be finished much faster being riden by more powerful rider by denting Al 7075 teeth rather than normal abrasion wear, because even hardest aluminium alloy is much softer than hardened steel - you can hit a sample with the hammer, and it's dented easily.
Lightest bikes are usually 1x, but this one is 2x. I bet it will be much lighter if he ditch those fd
And remove front brake. Who needs a front brake for climbing?
@@williamko4751 Remove the rear brake instead. Shorter cable to the front. Better to have brake up front for stopping as well.
I hope the titanium bolts have also been cut down?
"We could use your support" was a worrisome comment. ☹️
That said, I'll always be a fan of Red 10. It was way ahead of its time and is still an impressive mechanical gruppo. I loved the bike i had it on.
Jason Woznick of Fairwheel Bikes in Tucson, Arizona did a 2.7 Kg road bike.
Yikes! I've eaten biryanis that were heavier than this bike.
I dont know a thing about road bikes but in downhill bikes i learned that when you go too far in weight savings parts starts to break or bent.
It would be interesting to see a durability test in these ultra light weight builts, in a real world without a super light rider in a ultra smooth road.
Dude, please send some F16 here to Ukraine, we need it so much(
We are with you if we can ever get the US congress off their butts long enough to send you money! Probably training your pilots here right now. Praying for you guys! 😢

That's a quarter of the RAF!
Oh no!
Nice video! I seem to remember one of the mountain biking journalists may be Steve Worland or Chipps building the lightest possible mountain bike. The only conclusion I remember was that it rode like a pig...
Small cables are stupid. Doesn’t save anything lmao and they’ll break, rather than brake
Well, every component has been compromised in some way to save the last bit of weight. It's stupid, shaving off those final 3 kg off a bike is not worth it at all.
@@glossymouse7712 lol the same can be said for shaving a bike down to 7kg. If you have trouble riding a 10kg bike fast up inclines it's a "you" problem
@@kennethg9277 I agree, when I started cycling I couldn't go up inclines at all cause "my bike was too heavy" or something. 2 months later I was going up steep inclines in the top gear.
The next time I'm getting a tuneup at Fairwheel, I am going to ask about this bike. Can't believe it is in my backyard but haven't see this before.
Downtubeshifter and regular shifter, 2000s trek vibes 😅
The freehub is the best thing about this monstrosity of a bike. I can't imagine being such a weight weenie that I must own the highest possible everything; train harder and get fitter if you want your bike to feel lighter.
My bike weighs around 16.5 lbs with nothing on it and I don't even feel it because I weight train daily from November-April, ride the trainer from January-whenever the weather breaks (March/April), and by the time I'm back on the road I've gotten so much stronger that my bike feels like it weighs nothing even when it's loaded up
F-16 pilot: "hmmm.that's a helluva light bike..over"
