1x in the pro peloton...

22 Sep 2017 13:35

What says everyone?

http://www.cyclingnews.com/news/aqua-blue-sport-to-compete-on-3t-strada-disc-bike-with-1x-drivetrain-in-2018/

an 11-40 cassette with 1 chainring is going to give basically the same range as a double, mid and compact with 11-28 if you use the biggest chainring.

I'm a little surprised they haven't gone full Eagle with 12x and a 10-50 to be honest...

Denifl would have never won that Vuelta summit finish with that gear. But Andy Schleck would probably like it.

I'm not opposed to it, but I guess my question is why? Aren't you guaranteed to have just as many gear problems with such a wide sweep on the cassette and a large derailleur?

I think getting the Eagle derailleur to work with the road levers still requires a hack, no? Not to mention, the precious roadie aesthetic suggests they don't want cassettes that are half the diameter of a wheel.

My issue would be with the spacing of gears at the top end of the cassette. During the mountains of a GT you will want to be as comfortable in your pedalling as possible. I'd also want some assurance that the chain won't drop on poor roads or cobbles too.

I could see it working well on long, flat races like Milan-San Reno though.

My thoughts exactly, unless you use chain catchers or a MTB style derailleur.

The CX pros that use 1x aren't having any of these problems, I haven't. What makes you guys think cobblestones are the exception? After all, the whole point of 1x was to reduce the frequency of skipping gears and dropped chains in the rough.

I was more meaning I'm surprised Sram haven't issued them with a fully functioning Eagle road group. The massive cassettes do look weird, but it is a disc brake bike so in for a penny... :)

Yes, I really appreciate the cadence adjustability that a closer ratio 10 and 11 speed cassettes (e.g 11-25 or 11-27) gives me, specially when climbing for extended periods and/or matching the speed of a group I'm riding in.These things would also seem to be important to pro-riders. I just wonder how they will like having to ride with slightly sub-optimal cadence on their 10-50 cassettes.

As to your second point, they'll all ride with chain guides, I'm guessing.

This 1X trend seems like a fashion statement.

Ok, being from Australia I don't follow CX that closely. I know that MTB setups are using chain guides, what about the CX setups?

Gear spacing would be less crucial for CX though as the hills will be far shorter and groups are smaller too.

Chain guides for 1x are just an insurance policy. Some do some don't. I'm not inclined to venture too in depth into that just because the stark difference between the two disciplines. MTB of course, CX/road unnecessary, but some will situationally dependent on the course. Oh well.

Re gearing; I was an early adopter of 1x while living in Colorado and regularly rode categorized climbs in my backyard, and most of the rest that span the Front Range and never had a problem with the gear spacing.

In all honesty, I think we can place 1x speculation and innuendo right beside disc brakes.

I've been crunching the numbers and something like a 50 tooth front paired to a 12 speed 10-40 would give greater range than an 11-30 with standard 53-39 cranks. A 48 tooth front would still give plenty of options, when paired to a 10 tooth. I'm warming to the concept...

BTW, as an early adopter, does this mean you've been testing SRAM :eek:, or messing around with Campag stuff?

Sure, but why the...:eek:? I think I've stated on this forum multiple times that I've always liked Sram, especially 1x. I've had a couple Sram groups in the last decade, but since they never (and still can't) figure out how to make a decent front derailleur 1x was a welcome change. Also ran Shimano Ultegra as 1x for a bit, low and behold their front derailleurs are also getting worse. And yes, as we speak right now I'm Frankensteining an old Campy Athena 11s group into a 1x to see if the gearing would justify an H11 purchase and removing the front shifting parts out of the lever.

Oh, from memory I thought you were not a fan of Sram and their reliability... I must have been thinking of Bustedknuckle.
