I think they should attach a 12-spd cassette to a crank and replace the front derailleur with another rear derailleur so they can have 144 speeds. Maybe also throw a classified hub on there for hilly stages.
1) How do you get the aero benefit of losing the front mech if most cyclists substitute that for a chain keeper? 2) 1x does NOT give a better chain line, except in the middle of the sprocket, so maybe in 3 or 4 gears only. In the highest or lowest 3-4 gears, the chain will be more 'bent' than a 2x in the right combination.
You get an aero benefit because you have a narrower chainring (you only have one instead of two) and because the sram front mechs are absolutely massive. The idea with the better chainline is that you set the bike up in a way that you get the good chainline where you actually need it and the worse one when you are just sitting in the pack.
1x for flatter terrain, 2x for the hilly stuff... If the difference is so important, you can likely afford both. As an engineer who loves simplicity, rec rider on pretty flat terrain, 1x is plenty for me and my wife.
I rode a 1x for a while on the road, with a small chainring at the front and a big cassette on the back. It didn't work for me as an amateur rider, it was great for steep climbs (which is a bonus round my way in the Peak District), but I had no big gears for the descents. Was so happy to switch back to my double chainring. I can't see it catching on for casuals.
Yeah Roglic using 1x in the final time trial and then dropping his chain is a brilliant poster for going 1x. If he wasnt so far ahead and ended up winning you can guarantee it would be a big deal.
Back in the late 1990s, the manufacturers were telling us we needed 3x groupsets. Once everyone bought one of those, they went back to pushing 2x groupsets. Now they are telling us we should have 1x groupsets. I expect the cycle will repeat.
But in the 90s I’m guessing the cassettes were like 8 speed instead of 12 paired with standard 53/42T chainrings so it’s hard to make direct comparisons.
Jonas Vingegaard 2 yrs ago when he made headlines TDF up the Ventoux when he gapped Pog he was on his large chainring all the way and uses the large chainring more than most riders
@@trentvlak on road bikes: rim>disc I've owned about 6-7 road bikes and around that number in CX and gravel bikes. I've never said to myself "I wish I had discs on road bikes." I live in a mountainous area and cannot go 10 miles without doing over 1k of climbing.
I have a 1X gravel bike, which is also my road bike. It’s my own mullet build - 42 tooth SRAM Force chain ring up front, GX Eagle 12 speed, 10-52 cassette at the rear (GX Eagle derailleur). Gear ratios have been great for me on climbs. Just a slow and steady pace. I ride solo, so I don’t know if my 42-10 combo would be able to keep up in a group on flats, but I’m in no hurry to find out. Pretty happy with my set up. Love the simplicity of just the one chainring. Oh, and I have semi slick tires instead of knobbies, because the majority of my rides are on road anyway.
1x can work for pros because, with 2x the W/kg of us mortals, they climb 2x faster again gravity, but only go 1.3x faster in the flats when fighting wind. (Because aero power is proportionl to speed cubed, but gravity is linear). This greatly reduces they practical gear range they need.
I think the switch to SRAM has been very insightful into the JV team with numerous riders on 1bys and other non-traditional setups. The R & D department at SRAM must have had fun trying to figure out if the savings are worth it from aero to drivetrains to chain lines to gear ratios to weight. I am so excited to see the switch to lower gear ratios, I'd love to see the intel on gear ratios for the hill climbs. My guess it is going to be course-dependent on which gear ratios they are given with a close to 1:1 for the hilly stages and then go back to a sprinter gearing for drivetrain efficiency for the sprint stage finishes.
1x also seems to gain popularity in the gravel scene, too. A few years ago, it seemed relatively evenly split and at this year's Unbound I had the impression most of the heavy hitters were running a 1x mullet setup coupled to a big chainring. I have been running a 1x12 SRAM setup on my road bike for a little over 2 years now, and it is excellent. I live close to proper mountains, and you can definitely live without the front chainring. Ideally, I'd like a 10-39/10-40 cassette for a little more range, but 10-36 works very well.
The biggest issues I find with 1x on the road bikes for general riding is the gear steps, When I would ride with someone who had a 1x, me with a standard 2x, on the flats was fine, but every time we came to a relative steep climb, when they would shift to an easier gear, they would slow down so fast that I would run into him due to the large steps in the gear range I run 1x on my cyclocross and triathlon bikes, but run 2x on my road bike as a all round terrain If the pros are running one 1x, they are going to have their gearing set accordingly to the terrain of that stage
sram 1x also has less lag in shifts than the 2x as its not waiting to see if you are hitting the other shifter for a front shift. Maybe Jonas didnt like the delay?

Still no chain guide. The smart setup is an MRP chain guide with sram 1x. Youl would think JV would learn something from Roglic's chain drop in the giro TT.
For a while I used a 2x with 35-48 and a 10-36 cassette. I found that I never used the small ring. You do also have some aero gains.... however you lose some watts by cross-chaining. You will also have more limited gear ratio with bigger spaces in between gears. Also 2X12= well realistically probably 14 or maybe 16 gears? Having said all that I would still love to see it happen!
i'm not conceding it, but planning to go 1x. The number of times i need do get on the small chainring here in Denmark, as good as zero. one point of gearshift failure less.
I run a 44t w/ a force 10-36 on my CX bike and it covers pretty much all the bases. Sometimes for gravel I'll throw on the 10-44. Some gaps in the middle of the cassette are a little more than I'd like, but its perfect for road training, CX racing, and gravel racing all on one bike. I don't really see the benefit on a bike meant just for riding on the road. No need for a clutched derailleur, and I feel the benefits of smaller gaps and wider range on a 2x is worth the few extra grams. Most of these bikes can still hit the UCI weight limit with a 2x system anyways.
Forget the 6.8kg limit. Make TDF riders ride the same equipment for every stage. 1x might work on a stage but you can bet they won't ride it every stage, like we would with our bike.
We had 6.8 kilo bikes forever, so weight saving point is irrelevant, 5 watts saving from removing an FD sitting in consistent turbulent flow due to pedalling is also an unverifiable claim. In short SRam is pushing BS marketing stunts and BS products like they have been for the past bunch of years, they got extremely lucky Roglic didn't lose the GIRO due to 1x, I hope they succeed in making Jonas lose TdF solely due to their BS and pay the price for it.
Sram is notorious for pushing stuff like this, meanwhile solving real problems with their drivetrains (mostly their front derailleurs) they just don't care. We saw that with their new Eagle "Transmission", and now we're seeing it in their road 1X setups aswell. I mean, I love Sram Eagle, but instead of improving on the derailleur hanger, which literally prevents your RD from snapping, they just ditched it and created a whole lot of new problems, especially for frame manufacturers.
I have a SRAM Rival setup with 48/35 and a 10-36. I've considered going 1x with a 48 or 46T chainring as I've done a couple fast group rides recently where I've not left the big ring. (easily verified through the AXS data) Though I wouldn't want to miss the

I was mountain bike guy before got to the road bike, I was surprised how reluctant road biker to the idea of 1x chainring. People can't product more than 200W power still want a 52-46t chainring. I ride road bike for 3 years, and I am always using 40T 1x chainring with 10-33T cassette. It's more than enough for my 200W leg. People can't believe I use 1x chainring, I think road bike people just don't understand how awesome 1x is
I’ve got a mullet 1x with 10x52 on my new Enve custom road. I’m the same, came from mtb and have never run 2x, seems so silly to have to switch chainrings all the time.
@stinkybeam - ran a 1x setup (42T and 11/32) on one bike for a race league last year and was perfect, never ran out of gears and zero problems. For anything that doesn't include epic climbs like Ventoux or Pikes Peak then 1x is fine for road bikes.
I run a 10-36 cassette with a 42-tooth chainring on my road bike. I spin out at about 65 km/h, which is about as fast as I want to go and still pedal on public roads with traffic. For most people even a 38- or 40-tooth chainring would be plenty fast enough in practice.
@@fatpinarellorider And you have annoying front shifts. Even when I was running 2x or 3x, I'd only reluctantly shift chainrings. A 1x bike feels much better to me. As far as gearing is concerned, my 10-36 cassette feels (and indeed is) as tight as the 11-speed 11-32 cassettes (Shimano and SRAM) I used to run. Plus, I come from the MTB side, and I feel comfortable at a wider range of cadences. Once you get used to it, I doubt it is an issue.
Considering that i live in a very hilly terrain area, and i ride and race my cross bike in road races and have very few if any issues, (Trek Boone 2023 with FFWD RYOT 33 and Challenge Criterium RS 27 tires) and i ride a 36t cassette with a 42t chainring, (sometimes 44t if its a flatter race), and my gearing, although hard if i have lots of gear, is usually enough for me to ride anything. I would absolutely put a 48t chainring on if my frame could handle that, and pair it with a eagle cassette. Bigger gears means less resistance. But also means bigger jumps between gears.
What I'd really like is a reduction gear in the hub or bottom bracket, so that when you're forced to a sudden stop by traffic, you can get going again even you where in the 50-11 gear. Not for the peloton, but a grace for us weekend warriors and commuters!
Since I haven't ever properly ridden an indexed derailleur, I'm wondering if they are more prone to failure since they encourage the risky practice of shifting with full torque and speed. Maybe a double with a more narrow rear spacing would be more reliable. Or just stop grinding the gears. 😊
Simple fact is 99% of bike riders can get on very well using a 2x11 gear set up. No a single chainring DOES NOT remove the issue of chain line. One small and often overlooked factor for consumers. Cost and Availability of spare parts! What Pro teams do to gain tiny advantages and/or please their sponsors HAS VERY LITTLE to do with people who then follow the Industry driven trends as consumers.
Im still using the '90s Mario Cipollini Taiwan-made time trial (with the tiger paint job) bike frame with the wheelwell design in the seat tube coz i have the conviction that its the progenitor of aero road bicycle design (and now setting the precedence)
I think they're going to just use whatever groupset, ring size, gearing suits each stage. Roglic doing so at the giro worked wonders. It's something that seems so obvious, when things like a bike change mid-stage has become fairly common place. Are there any rules against that?
Bike changing mid stage just seems a bit wrong to me. Surely part of the challenge is choosing a bike set-up that will see you best through that stage. I know we saw it in the Giro, but I don’t think it added anything.
yea thats true, i think the 1 by isnt replacing the 2 by in near future especially not for us amateur riders. as you said they put on whatever they need for the stage. on some TTs they ride a 53 single chainring, on some a 60 single and on some a 2 by with 53/44. and i cant imagine going up the mountains in my area(some have sections above 20%) with a 48/36 and im sure this counts for 98% of all riders. if i would live somewhere flat like in northern germany, netherlands or denmark i would definitely consider a 1by, but youd stil have to change when you are going on holidays fe to mallorca.
Aqua Sport blamed 3T for their collapse, based on them being forced to use 1by. I like them having to just use one bike too, think that's all part of the challenge. But as it's part of the pro culture now, I can see it happening with groupsets, different bikes etc.
If he cared so much about weight, he could save way more weight switching to rim like Pog used too. You say driveline efficiency is better, but is it, I do not understand that claim really. You would spend way more time on the lower or higher end of the cassette surly? A very hilly up and down stage he is going to be in the 10 or 33 most the day.
Chainline can be better, then 2x, if u use big-big or small-small on a 2x. No one in their right mind do that often, and in case of big-small or small-big, 2x has to have better chainline. They use a chain catcher, and thats almost as much aero drag as a fron mech? Although sram front mech is chunky, so micht be some savings there. But its almost neglectable, since he rides fast in peloton, and slower uphill alone, where the weight is more redundant. Is it lighter? Maybe, but he cant have good cadence on low speeds. Probably will use as an advertising, on stages where only has to finish in the peloton, and hope the chain doesnt come of like it used to be.
Because disc brakes are faster aka more aero brake faster brake more consistently vs 1x for the stages he will use it on has no difference just lighter not a good comparison at all
Im not against 1x but I’m a bit skeptical that it’s the next best thing in road cycling tech. Effectively it means fewer gears and bigger jumps between gears. But the cervelo s5 weighs over 8kg so they have to try and get the weight down somehow.
Isn’t half the reason 2x is more weighty (and probably less aero) nowadays, because of the big ugly battery and electronics stuck on the top of the derailleur? The reason 1x was deemed as a failure before, on the tour, was that you either have the range of gears but big jumps in between or you have less range with smaller gear jumps. It’s always a compromise. What’s changed since then?
Agreed, those batteries certainly aren’t helping the weight - the gaps or lack of range is definitely still a compromise but has improved since the last time thanks to an extra gear (12 vs 11 speed) and that 10t sprocket at the back. We’re still not yet convinced though!
Was 3x for a bit, then 2x, now 1x. Sure the cycle will repeat. Next “revolution” might be belt drive??? Bike companies keep having to re invent the wheel somehow, or we’d all be keeping our bikes 20 years plus.
Make that 14 and we have the same number of unique gears (with relevant difference between them) that today drive trains give us. Let's not pretend they couldn't do it today, if they wanted to. They have dragged this adding of gears out long enough. Three decades for 5 extra sprockets. Btfo Shimano, we're fed up with this artificial throttling of innovation.
Think for yourselves, too many cyclists blindly copy what the manufacturers tell them to use. I analysed what I used and saw I do not need a 2x, I now have a 1x and 8 speed cassette which gives me all the range I need with a chain alignment that is pretty straight and does not wear all the cogs .
He wont be using that ratio in the hills. Jumbo clearly switch between R5 and S5 depending on the profile and I'm guessing his R5 will be suited for the occasion
Last year my front derailleur cable snapped on the commute to a hilly group ride. I just couldn't spin enough to match the speed of the others then. I was dropped as soon as it got flat after the first descent. When racing I never touch the small ring or almost never, because we come so fast on the bumps that the momentum you have prevents downshifting to the 39 tooth ring
Sod it I’ve been using 1x for years on my road bike. I race Mtb and it makes so much sense for both disciplines. Why the peloton are only just catching on now when Mtb have been doing it for years. We don’t drop chains either, narrow wide chainring and a clutch mech = happy days and speed.
If your pace is changing with the change, your timing is off or your swap was the wrong choice. But, on constantly changing terrain, it can be easy to mess up. It's why I much prefer 1x on my gravel bike. So much easier.
Jumbo Visma technical experiments seem to be costing riders dearly this year. 1x in Milano San Remo and hub compressors in Paris Roubaix 🤕 Roglic at Giro not loosing the race along with the chain was pure luck and a risk taken without benefits. Gearing could have been achieved with any setup and aero on a climb 🙄 I bet SRAM are paying handsomely to have their 1x promoted.
Had more chain drops on my 1x commute bike than any on all my other bikes. The lack of variety in mh hilly area , takes the pleasure of cycling at times.
Pro bikes can easily achieve the 6.8kg limit with 2x. Drivetrain loss will probably be much higher in 1x with wonky chainline at the ends of the cassette and 10t loss. The aero benefit is marketing BS.
Absolutely not. I dont have someone to push me when the incline gets steeper, or a team car with all my bikes to choose from. That stuff is only for the pros race days.
Your chain ring can be situated in closest alignment with the 3-4 gears most often used, (which potentially has a .041 W saving at 63 kph in 71%RH at 28°C, 101.2kPa)
BS he had not been pushed into it by SRAM. Hense why some climbing appears and he is on a x2. This is advertising. The marketing teams will have us all needing a x1 and x2 bike soon.
I think they should attach a 12-spd cassette to a crank and replace the front derailleur with another rear derailleur so they can have 144 speeds. Maybe also throw a classified hub on there for hilly stages.

I’ve got a mullet 1x with 10x52 on my new Enve custom road. I’m the same, came from mtb and have never run 2x, seems so silly to have to switch chainrings all the time.
@stinkybeam - ran a 1x setup (42T and 11/32) on one bike for a race league last year and was perfect, never ran out of gears and zero problems. For anything that doesn't include epic climbs like Ventoux or Pikes Peak then 1x is fine for road bikes.
I run a 10-36 cassette with a 42-tooth chainring on my road bike. I spin out at about 65 km/h, which is about as fast as I want to go and still pedal on public roads with traffic. For most people even a 38- or 40-tooth chainring would be plenty fast enough in practice.
It's all about closer rear spacing. 2x setup allows you to run a tighter cassette, get better chainline, that's why.😉
@@fatpinarellorider And you have annoying front shifts. Even when I was running 2x or 3x, I'd only reluctantly shift chainrings. A 1x bike feels much better to me. As far as gearing is concerned, my 10-36 cassette feels (and indeed is) as tight as the 11-speed 11-32 cassettes (Shimano and SRAM) I used to run.
Plus, I come from the MTB side, and I feel comfortable at a wider range of cadences. Once you get used to it, I doubt it is an issue.
Considering that i live in a very hilly terrain area, and i ride and race my cross bike in road races and have very few if any issues, (Trek Boone 2023 with FFWD RYOT 33 and Challenge Criterium RS 27 tires) and i ride a 36t cassette with a 42t chainring, (sometimes 44t if its a flatter race), and my gearing, although hard if i have lots of gear, is usually enough for me to ride anything. I would absolutely put a 48t chainring on if my frame could handle that, and pair it with a eagle cassette. Bigger gears means less resistance. But also means bigger jumps between gears.
What about chain friction on the biggest and smallest cog ?
What I'd really like is a reduction gear in the hub or bottom bracket, so that when you're forced to a sudden stop by traffic, you can get going again even you where in the 50-11 gear. Not for the peloton, but a grace for us weekend warriors and commuters!
You could shift yourself?
Gear boxes like the Shimano Alfine allow you to change gears while stopped. It is very convenient for a city bike.
Indeed, but I want a road bike for covering the outside of city stretch. And because it's more fun...
Since I haven't ever properly ridden an indexed derailleur, I'm wondering if they are more prone to failure since they encourage the risky practice of shifting with full torque and speed. Maybe a double with a more narrow rear spacing would be more reliable. Or just stop grinding the gears. 😊
Simple fact is 99% of bike riders can get on very well using a 2x11 gear set up. No a single chainring DOES NOT remove the issue of chain line. One small and often overlooked factor for consumers. Cost and Availability of spare parts! What Pro teams do to gain tiny advantages and/or please their sponsors HAS VERY LITTLE to do with people who then follow the Industry driven trends as consumers.
No reason to remove the front derailleur. It works great and gives you more gears. The weight is not significant.
But muh aero! It give me like five Wotts 4 shuah!
Weight isn’t significant on mechanical, but electronic with that big arse battery…😅
Doubt those are the new Red hoods, especially when Movistar leaked prototype Sram hoods that looked much more different last December.
Im still using the '90s Mario Cipollini Taiwan-made time trial (with the tiger paint job) bike frame with the wheelwell design in the seat tube coz i have the conviction that its the progenitor of aero road bicycle design (and now setting the precedence)
I have 1x12 sram on my Trek Madone now since two years. It’s absolutely enough gears for me here around Munich.
Riders should be REQUIRED to ride the same group set the entire TOUR.
Make it like NJS keirin
Single chainring in front is single purpose, like riding only downhill or only flat or only uphill.
SRAM also make a 10-36 capable RED derailleur. So they must have thought 33 is enough..?
We see he's back on 2x for today's stage...interesting stuff but we'd much rather use an XPLR 10-36 than that 10-33 if it was us!
I think they're going to just use whatever groupset, ring size, gearing suits each stage.
Roglic doing so at the giro worked wonders. It's something that seems so obvious, when things like a bike change mid-stage has become fairly common place.
Are there any rules against that?
Bike changing mid stage just seems a bit wrong to me. Surely part of the challenge is choosing a bike set-up that will see you best through that stage. I know we saw it in the Giro, but I don’t think it added anything.
yea thats true, i think the 1 by isnt replacing the 2 by in near future especially not for us amateur riders. as you said they put on whatever they need for the stage. on some TTs they ride a 53 single chainring, on some a 60 single and on some a 2 by with 53/44. and i cant imagine going up the mountains in my area(some have sections above 20%) with a 48/36 and im sure this counts for 98% of all riders. if i would live somewhere flat like in northern germany, netherlands or denmark i would definitely consider a 1by, but youd stil have to change when you are going on holidays fe to mallorca.
Aqua Sport blamed 3T for their collapse, based on them being forced to use 1by.
I like them having to just use one bike too, think that's all part of the challenge. But as it's part of the pro culture now, I can see it happening with groupsets, different bikes etc.
If he cared so much about weight, he could save way more weight switching to rim like Pog used too.
You say driveline efficiency is better, but is it, I do not understand that claim really. You would spend way more time on the lower or higher end of the cassette surly? A very hilly up and down stage he is going to be in the 10 or 33 most the day.
Chainline can be better, then 2x, if u use big-big or small-small on a 2x. No one in their right mind do that often, and in case of big-small or small-big, 2x has to have better chainline.
They use a chain catcher, and thats almost as much aero drag as a fron mech? Although sram front mech is chunky, so micht be some savings there. But its almost neglectable, since he rides fast in peloton, and slower uphill alone, where the weight is more redundant. Is it lighter? Maybe, but he cant have good cadence on low speeds. Probably will use as an advertising, on stages where only has to finish in the peloton, and hope the chain doesnt come of like it used to be.
Because disc brakes are faster aka more aero brake faster brake more consistently vs 1x for the stages he will use it on has no difference just lighter not a good comparison at all
@Bnet disk brakes are not more aero at all. Do not believe the marketing lies
I agree; cross-chaining losses over the course of a race are probably higher in 1x.
@@bnet7608You’ve been watching too much GCN and have been conned by the marketing.
SRAM realized they can't fix the drop chain and decide to eliminate the cause - front derailleur.
1X on a TT bike on a flat-ish route is fine. Aero cranks can save a tonne of watts. Horses for courses.
I used 1by road bike on SRAM AXS. It was pretty OK for terrain i am cycling in.
Im not against 1x but I’m a bit skeptical that it’s the next best thing in road cycling tech. Effectively it means fewer gears and bigger jumps between gears. But the cervelo s5 weighs over 8kg so they have to try and get the weight down somehow.
I live with nice Southern California mountains to contend with. I love to climb and bomb right back down, I will always keep 2x.
For total non added value: Meur (aka Muur) is Dutch slang for a foul stench as in: Het meurt hier als de CENSUUR!
Isn’t half the reason 2x is more weighty (and probably less aero) nowadays, because of the big ugly battery and electronics stuck on the top of the derailleur? The reason 1x was deemed as a failure before, on the tour, was that you either have the range of gears but big jumps in between or you have less range with smaller gear jumps. It’s always a compromise. What’s changed since then?
Srams marketing budget?
Agreed, those batteries certainly aren’t helping the weight - the gaps or lack of range is definitely still a compromise but has improved since the last time thanks to an extra gear (12 vs 11 speed) and that 10t sprocket at the back. We’re still not yet convinced though!
Nothing has changed.
I think the SRAM Red standard rear derailleur max low gear is 36t, not 33t
Need to quantify friction and wear from extreme cross-chain positions.
How can a single chainring provide a better chain alignment?
May the Fly rest in peace 🙏
Was 3x for a bit, then 2x, now 1x. Sure the cycle will repeat. Next “revolution” might be belt drive???
Bike companies keep having to re invent the wheel somehow, or we’d all be keeping our bikes 20 years plus.
Why are you always trying to get road bikes onto 1x?🙄
The weight saving is almost certainly inconsequential. What appears to be the higher risk of a shipped chain may not be.
13 speed and high gear bias like campy Ekar and just abou 99% of people are going to be fine with it.
Make that 14 and we have the same number of unique gears (with relevant difference between them) that today drive trains give us.
Let's not pretend they couldn't do it today, if they wanted to.
They have dragged this adding of gears out long enough. Three decades for 5 extra sprockets. Btfo Shimano, we're fed up with this artificial throttling of innovation.
99% of people who don’t race
Good luck to all club riders trying staying in Zone 2 on a 13% inclination with 50x33.
Oof that requires some fitness level even with an 39-33.
It seems Sram FD is so unreliable that it's only possible to run 1x. There was pictures where JUMBOs got dropped chain on chill coffee rides
So, going 1x worked really well in the Giro TT didn't it?
Oh wait, the chain dropped, never mind!
@@whynotride327 Who won dude... 'nuff said.
Did you count the sprockets? Is it already 13speed?
We did, but only 12
If you want to know what's coming to road bikes, just like at mountain bikes from 2015
Think for yourselves, too many cyclists blindly copy what the manufacturers tell them to use. I analysed what I used and saw I do not need a 2x, I now have a 1x and 8 speed cassette which gives me all the range I need with a chain alignment that is pretty straight and does not wear all the cogs .
I Think Jumbo, as the biggest and best team in the world, know what they are doing😊
I ride 1x on my Cervelo S5 and Dogma F12... Never miss the the front derailleur
What gear combos are you using? The gear jumps on Eagle have me in shambles all the time on the 1x road bike
I dont know whats all this fuss about 1 by. The chain line is appalling.
Jumbo Visma doing anything to avoid using the horrible sram front mech.
Thats the take home
Weird to classify Classified as 1-by
He wont be using that ratio in the hills. Jumbo clearly switch between R5 and S5 depending on the profile and I'm guessing his R5 will be suited for the occasion
I would only consider a 1x road bike if the cassette has an 18T cog in it.😊
Name checks out
@@Bonboy2012😂
Last year my front derailleur cable snapped on the commute to a hilly group ride. I just couldn't spin enough to match the speed of the others then.
I was dropped as soon as it got flat after the first descent.
When racing I never touch the small ring or almost never, because we come so fast on the bumps that the momentum you have prevents
downshifting to the 39 tooth ring
it's not really a 1x if they use a classified hub though
If I had a problem with not knowing how to spend money I for sure would go for a 1 bike! :P 🙂
Saves weight, perhaps, but one can't go lower than the UCI weight limit.
Tdf morphing (going hybrid)
If they go for 1x setup they definitely should run a clutch rd
Sod it I’ve been using 1x for years on my road bike. I race Mtb and it makes so much sense for both disciplines. Why the peloton are only just catching on now when Mtb have been doing it for years. We don’t drop chains either, narrow wide chainring and a clutch mech = happy days and speed.
Gear ratio gaps matter a lot more on the road.
cound not disagree more.......cross chaining.......costs too many watts. It's a gimmick for bike companies to get same money for one less ring, IMO
I am existed to see 1x gaining adoption. You never need to shift two rings at the same time which results in a change of pace and muscle pain.
If your pace is changing with the change, your timing is off or your swap was the wrong choice. But, on constantly changing terrain, it can be easy to mess up. It's why I much prefer 1x on my gravel bike. So much easier.
Or just use automatic electronic system
No way the Pro's won't have a ×2by 4 the TdeF. Not heading up those Billy Goat Mountains with ×1 by .
Weight loss doesn't matter. UCI states 6.8 kilos
Love my 1x.
what happened to the fly ?
Jumbo Visma technical experiments seem to be costing riders dearly this year. 1x in Milano San Remo and hub compressors in Paris Roubaix 🤕
Roglic at Giro not loosing the race along with the chain was pure luck and a risk taken without benefits. Gearing could have been achieved with any setup and aero on a climb 🙄
I bet SRAM are paying handsomely to have their 1x promoted.
well, it's not just promotion, but development, it's an investment that they believe is worth pursuing
Had more chain drops on my 1x commute bike than any on all my other bikes. The lack of variety in mh hilly area , takes the pleasure of cycling at times.
Next year would be as styro frame for extreme weight saving.🤣
Would never consider 1X. Too wide of a gear spacing.
Pro bikes can easily achieve the 6.8kg limit with 2x. Drivetrain loss will probably be much higher in 1x with wonky chainline at the ends of the cassette and 10t loss. The aero benefit is marketing BS.
Not going with a 1X if makes a fly go up my nose.
Absolutely not. I dont have someone to push me when the incline gets steeper, or a team car with all my bikes to choose from. That stuff is only for the pros race days.
5:18 Better chain line in a 1by? Sorry what?
Your chain ring can be situated in closest alignment with the 3-4 gears most often used, (which potentially has a .041 W saving at 63 kph in 71%RH at 28°C, 101.2kPa)
1x to compensate for the new heavy ass bikes
bikes... am i right?
1x not for me my shimano front derailers all work great. Interesting is a company who has had a history with front derailer problems is pushing' 1x
I only ride 1x. Absolutely no interest in going back to a front mech
BS he had not been pushed into it by SRAM. Hense why some climbing appears and he is on a x2. This is advertising. The marketing teams will have us all needing a x1 and x2 bike soon.
I did considered it but I choked.
