    A 10 allows for wider gear range and smaller chainrings.

    I don't think drivetrain manufacturers should have to guarantee backwards compatibility. This is Grant Petersen-esque logic which would have kept the industry stuck in the past: quill stems, friction shifters, bar end shifters, steel only frames and forks, 7 speeds is good enough, etc.

    10 tooth is a great idea for functionality; maybe not so great for supporting prior investments.

    They are indeed 1 piece...powermeter/chainrings. Just got a message from our rep stating 'with proper drivetrain maintenance we're expecting 6-7 years from the rings'.

    I love that SRAM is looking towards adding some sort of functionality with the extra gear, even if it really doesn't appeal to me at this time. I also like that they got several other manufacturers online with the required hub configuration ahead of time. It just makes the transition that much smoother. However, if Shimano adopts another hub standard on what I assume they're developing now, it's just going to be a huge mess. Kinda like bottom brackets.

    Let's be serious, though. This is a very expensive groupset that requires a significant investment to install on an existing bike and will likely only be installed on top tier bikes for the near future. Until Force goes 12 speed and Shimano introduces their version, I don't expect that we'll see a wholesale rush to 12 speed drivetrains. When that does happen (and it will), I'll be more than happy to scoop up a bunch of the "outdated" 11 speed stuff (that's still supported) and make my own move, as the NOS 10 speed market will likely be running dry by then.

    It's got very close gearing in back in your high cogs, and the 10t cog allows a smaller chainring setup which I think is great - much easier to stay toward the middle of the cassette on flat ground for me. The shifting is a bit faster in back, supposedly faster in front, but I didn't find it noticeably different in the front to be honest.

    It's a slightly different XD driver for road, but very similar, and it'll be fully compatible with the MTB 12 speed etap if you want to run a 1x.

    If you want to run regular road gearing and a double, the 11s setup will likely perform really well. I don't, so I'd absolutely get the new stuff.

    might be interested for a 12sp 1x system, but that cassette would be huge, like on mtn bikes. But eliminating the FD and left shift mechanism might help save some of the cassette weight gain. Hey we all used 2x6spd in the 80s.

    Thanks. Can you find out if one would need to send the crank to SRAM to have the power meter added or is that something that can be done outside of SRAM?

    If waiting for the latest thing is what you want to do you should never buy anything because the latest thing is always right around the corner. Or be set to change every few years.

    I'd get what suites your needs and budget regardless of what came before and might come afterwards.

    i have a stable of bikes all on shimano 11 speed, and I like to the fact that I can interchange wheels between bikes with ease. For people like me, I reckon they'll be hesitant to go to Sram 12speed due to

    1. cost
    2. XD wheels
    3. cost of XD cassettes (not sure why they're so expensive!)

    I barely find any benefit (if at all) going from 10spd to 11spd, so I'm wondering what would going to 12spd benefiting, other than to have the latest toy?

    Because they're machined from a single billet. Takes a comparatively long time to make one.

    Count me out. I'll ride my original eTAP until it doesn't work anymore and I can't get replacement parts. After that? I'll probably migrate over to Shimano Di2. Just recently moved to a DZero power meter too. The whole idea of replacing the power meter every time you wear out your chain rings is the most laughable thing I've read in a long time....

    Again, we're talking about an "apex" groupset. Once 12 speed rolls down a bit, I expect that Quarq 12 speed power meters with normal chainrings will be available. XD cassettes will likely come down a bit as well, as the need to be as light as possible is relaxed. Right now all we're seeing is the absolute top of the line, not what they can do with fewer restrictions.

    I'm still looking for that Force-level eTap group.

    I'd rather have an extra cog on an 11/28 cassette with my current crank than a 10 tooth cog - but perhaps I'm an anomaly.

    12 speed people will need to buy new wheels.

    Buying parts to hang on your bike is always easier than getting fit.

    Depends on who made your hubs. Some are a simple freehub swap. Shimano Microspline hubs made by DT Swiss or Onyx are just that.

    Most of the big manufacturers already make XDR freehubs, and sell a kit so you can fairly easily (in most cases) swap between them (to/from Shimano 11sp or Campy).

    It's still a bit of a hassle, but it's not necessary to buy new wheels if you already have one that can be made compatible.
