A cinch to fit.

Navigating bottom bracket shell standards can be a headache when you’re trying to customize your ride. The new Cinch interface system from Race Face offers an easy solution. The Race Face Cinch BSA Threaded 30mm Bottom Bracket allows you to experience 30mm spindles and a stiffer bottom bracket/crankset interface. The BSA 30 bottom brackets will fit your new Race Face Next SL cranks in a standard 68/73mm bottom bracket shell.

    It's a BB, works great with my Next SL crankset

    Good BB

    • Familiarity: I've put it through the wringer

    If you're running a race face crank, and you're bike is creaking, pretty good chance it's your BB. If you aren't looking to break the bank replacing it, this is your best bet.
    Best of all, they're super easy to install with the right tools.

    Crunchy RaceFace BB, replace it!

    • Familiarity: I've put it through the wringer

    Good option if you're looking to smooth up an old RaceFace BB.

    Does what a BB is supposed to...holds my crank set on.

    Unanswered Question

    Would this bb serve as a replacement/conversion for a carbon cannondale scalpel 2014 bb30?
    Thank you.

    Great so Far!

    • Familiarity: I've used it several times

    The RaceFace Cinch 30mm bottom bracket does what it is supposed to do, just make sure you have the correct tool to install it (such as RaceFace's own tool or the Park Tool BBT-79). After that it is game on and enjoy your ride.

    Wears out quick

    • Familiarity: I've put it through the wringer

    Came stock and worked fine initially. Less than a year in the bearings wore out and non drive side has seized up with the other getting close. I'd rather spend a bit more and get more longevity out of my bb.

    threaded is the way to go.

    • Familiarity: I've put it through the wringer

    SPun this BB into place and have had no issues. I do re lube the bb often to keep things working like they should.

    Birdie is better than Par

    Race Face has drastically improved the bearings in this bottom bracket. Sure they are a little stiff out of the box but loosen up after a few rides. Once broken in this bottom bracket offers a velvet smooth feel. Plus with this bottom bracket you can run any of the Cinch cranks from Race Face which are among the best cranks on the market. Make sure you install this properly or you will likely have issues with durability.

    Deserved bad reputation

      Cups weren't parallel, which caused tension on spindle, wearing out the bearings very quickly. Cranks wouldn't turn very freely, and the preload ring would just self-tighten as it rubbed on the bottom bracket every revolution. Love my Next SL cranks, but these bottom brackets have a bad reputation for good reason. Not a lot of options for a BSA thread, and the other ones out there are more expensive, but don't waste your time with this one.

      Good bearings, creak free

      • Familiarity: I've put it through the wringer

      Thank god some companies are still using threaded bottom brackets. RaceFace made a brilliant standard with their cinch cranks, allowing a 30mm spindle to be used with a threaded BB. This BB is great, the bearing quality has definitely increased compared to raceface cranks of old. They feel a bit tight right out of the box, after 3-4 rides they break in and spin smooth.

      Good value, chincy dust plate

      • Familiarity: I've put it through the wringer

      I'm a big fan of the turbine cranks and threaded bottom bracket--so I'm buying this for seamless installs. All has been working well with one exception--on install, on a couple occasions I've cracked the little plastic dust plate/washer thing that goes on the outside of the bearing ring to help keep dust/water out. Not sure if I'm clumsy or its just been bad luck--but be mindful of this when handling the washer or tapping the spindle through. Deducting a star for the hassle this has been for me--otherwise, another great product from the RaceFace folks.

      will Aeffect Cinch Crank Arms fit with this even if its a 24mm spindle

      picks up when you hammer down

      • Familiarity: I've put it through the wringer

      Raceface cranks? threaded BB shell on your frame? Yeah. This is the one you need.

      30mm spindle on threaded frame? YES!

      • Familiarity: I've used it several times

      Why settle with GXP or Shimano 24mm spindles? Thank goodness that we can now use 30mm spindle cranks on threaded frames.

      Silent crankin’

      • Familiarity: I've used it several times

      I chose to put the Cinch bottom bracket on my Santa Cruz 5010. Loving it. Smooth, silent, and stiff. Give me a shout if you want to talk shop.

      No Squeaks

        This BB served me well last season. No squeaks or issues whatsoever, plus Raceface has a great offering of cranks for this one. Easy to install, although it does require a proprietary tool from raceface.


        • Familiarity: I've put it through the wringer

        The Cinch system really allows for one crank set to be used between different bottom bracket standards. For your threaded frames, this is the one you need. Quick and easy installation, bearings are quite tight and stiff out of the box, and will require a little break in. A great system.

        Super smooth bearings

        • Familiarity: I've used it once or twice and have initial impressions

        The bearings in this bottom bracket are really smooth. Surely I'm putting more power to the rear wheel. Easy to install with their cinch specific tool (not Shimano).

        Easy Servicability

        • Familiarity: I've put it through the wringer

        The 30mm spindle provides a super stiff platform that spins smooth and silent even after a season of hammering. Pair with a set of Raceface Next SL's to create a ultralight cranks assembly.
