SRAM’s New Force and Rival 1 Drivetrains Apr 17, 2015


If you’ve ever wanted more versatility in your cross bike, touring bike or all-road bike on a 1x platform, SRAM’s latest product venture might pique your interest. XX1’s original success has since trickled down on the mountain side to the ever affordable GX plaform and now, both Force and Rival offer 1x drivetrains to accompany CX1.

You can now run up to a 42t cassette on SRAM’s 1x road levers, provided your wheels are 135mm spaced with XD driver compatibility. Or, opt for the standard 11-speed 11-36 cassette. With a range of X-Sync chainrings, you can achieve a wide range on your road bike as well.

Personally, I’m pretty stoked to see this versatility now offered from SRAM and can’t wait to see what else is to come from 1x road offerings. For some reason, I can’t help but gravitate towards the idea of a 48t Chainring with a 11-42t setup…

    “OMG! WTF? So now I HAVE to buy a whole ‘nother bunch of new stuff? Thanks Obama!”, etc.

  • Ultra_Orange

    That’s some fancy shit, still not sold on the real world advantages of dimples.

  • D0rk

    The idea of 1×10-42 on a do-it-all road bike excites me.

    Bonus factoid: For those that don’t want to or can’t run an XD driver, it appears that the MTBers have had success running SRAM cassettes with XTR 1×11 to get the bigger range, meaning the inverse should stay true and we’ll be able to run the 11-speed XT or XTR cassette on SRAM 1×11 without needing a new freehub.

    I’m hardly a proficient wrench by any means, but I struggle with understanding how in 2015 FD shifting is a problem and how this adds versatility when you’re halving the number of potential gears. I get that some of the ratios can match…but this feels like it’s addressing a problem that doesn’t exist…

    • John Watson

      I see what you’re saying but it’s kinda nice to not have to shift on the front. No dropped chains either…

      • David

        I agree it would be nice to not have to shift on the front in certain situations (I have been thinking of a 1x for CX, but I want to see if Shimano produces a dedicated system first) and as for dropped chains…well, this last CX season showed that that can still happen with 1x. I don’t think any manufacturer can create an absolute fool-proof way to ensure your chain never drops, unfortunately. Obviously this will significantly decrease the chances but I think if you were using this system in a racing platform, crits might be interesting depending on your cadence with the biggest ring possible in the system, you will still see some drops.

        no dropped chains, just ask wout van aert

    • Tommaso Gomez

      I agree, and I think a 1X setup would be really bad setup for long climbs or racing situations when you want small, incremental jumps in gearing. It would work fine for riding in relatively flat places or cities though.

    • Mr_Bridge

      If SRAM were discontinuing their 2x and 3x drivetrains in favour of 1x, I’d understand the widespread criticism and butthurt over this. But they aren’t. They’re offering another line. It either makes sense to you or it doesn’t. Made sense to me the moment I moved to London sixteen years ago and began commuting to work, prompting me to strip the superfluous shit off my tatty GT Borrego and run it as a 1x8spd. If narrow-wide rings or clutch RDs had existed back then, I’d have been all over them.

      • David

        Just for the record what I’ve presented is a pretty tame criticism and is far from “butt hurt,” whatever that even means. You’re talking about the commuter market which is not where this product is aimed necessarily, but is a fine application. However I’d suggest that if that is your main concern, there are plenty of suitable options currently for commuting, everything from a relaxed single speed to a triple in case there’s a climb or two on the way. It makes sense to me, mostly because I am not an idiot, but it doesn’t seem necessary, which is a different argument.

        • Mr_Bridge

          Nobody (not even SRAM) suggested front shifting is/was a problem. The ‘widespread criticism and butthurt’ that I spoke of is out there on a good few bike forums right now – that phrase wasn’t aimed directly at you, but your original post came across as ‘why make this, I don’t get it’ in its tone which is pretty much the same negative attitude some folks are taking towards this.
          The fact that I’ve been seeing people ride 1x drivetrains with mid-to-race-grade parts on a daily basis for nearly two decades tells me there’s a market for this – for once it’s nice to see a company come out with a solid (ie warrantied) setup that riders have been homebrewing for years.

      I don’t believe SRAM is saying front shifting is a problem or needs to get rid of them. I can’t help feel that most people are jumping the gun and assuming(not you) that SRAM is trying to get road cyclist/racers to get this group but its intended for TT bikes and especially gravel/adventure/rando riders since its one less thing to worry about without sacrificing gear range.

  • Morgan Taylor

    Love me some trickle down.

  • bgav

    Lot to be said for the simplicity, reliability and sequential shifting of a single ring. The clutch rear derailleur to minimize or eliminate chain slap on gravel/dirt roads, especially on washboards and bumpy descents is also very attractive.

  • Dobry

    More options! Great!

    What frame is that in the last picture, the one with the rival rear der?

    • Jacob Hunter Creighton

      Specialized AWOL Comp frame.

    I live in LA and run 1 X 10, 46_11-26 on my ”Training bike” I don’t race on the road( just ss cross a few times a year) so never felt like I need all those gears plus I am one of those idiots that has to be weird like mixing capag with sram and riding up GMR on a single speed, So this is perfect for me, I don’t mind climbing all day with the ratios I have know, this opens up a lot more possibilities while maintaining the simplicity I like. Fucking Awesome

  • Raoul Morley

    1×10 or 11 seems to make perfect sense if you live somewhere fairly flat I’m about to start running a single ring for round London and Essex and it’ll be great no duplication, less weight and all the ratio’s I need. I guess they won’t be right for everyone but for me pretty much perfect although an X9 rear mech is likely both lighter and cheaper…

    • Richard Evans

      Oddly I live in Colchester and been thinking of running 1×11 on my new bike. My only concern is the occasional trip to Wales etc where I definitely need more gears.

      • John Watson

        I ride a cross bike with a 1×11 (40t x 11-32t) and 40mm tires, up 18% grades on dirt just fine. You can now go up to a 42t and run a 38t chainring if you need more.

  • Eric Spinney

    I’m so pumped for this. My Enduro bike is 1×10, my commuter is 1×10, my cyclocross racer is 1×10. I’m so pumped for an affordable 1×11 group to upgrade my crux and enjoy the benefits.

  • Alex Hillis

    Nice that CX1 has a cheaper option. More excited about the GX line though. Cheers to cheaper! This is why I love SRAM, same form and function, just cheaper.

  • Jaap

    Why has CX1 disappeared?

    • John Watson

      It’s still there!

      • Jaap

        Where? SRAM website shows force 1 when I click CX1

  • Lemontime

    When? How much?

  • Frank

    I think it’s great SRAM are opening up 1x drivetrains to the mainstream. The days of hacking together mismatched road / mtb parts are over!
