    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.

    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.

    Birdie is better than Par

    • Familiarity: I've put it through the wringer

    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.

      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.


      • 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.

      So far so good

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

      When building up a new trail bike, the race face cinch 30mm spindle setup came highly recommended. I just recently finished the bike, but so far things seem great. I like the idea of the larger 30mm spindle to get maximum stiffness, and the weight of the aluminum RF cranks I is very competitive with even some carbon offerings. Excited to put some real miles on to put this to the test, but with the right amount of grease and torque I'm confident that this will be a smooth setup.

      Its a Cinch!

      • Familiarity: I've put it through the wringer

      I really like RaceFace's cinch system. The same crankset will work with pretty much any different frame, as long as you have the right BB. No need to buy a new crank if going from a frame with thread in BB to a PF30 or something like that. Just replace the BB and you are good to go!
      And this BB spins smooth, has taken quite the abuse, and has had no problems whatsoever.

      Unanswered Question

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