    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.

      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).

      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.

      I'm a fan of standards. Standards have come and gone when it comes to bikes. You now have to look at "platforms" and the RF Cinch helps you make sense of these platforms; for that I am thankful. Pick a Cinch crank, and match it to you frame's BB and you no longer have to figure out which adapter, converter, or widget you need to put your bike together.


      • Familiarity: I've used it several times

      The RaceFace Cinch BSA 30 bottom bracket works just as it should and is really smooth! The only thing I'm not too excited about is having to buy a special BSA30 wrench to install and remove it, but hey, you can never have enough tools, right?

      Hello, will this bottom bracket work with specialized s-works cranks, I'm trying to put this combination on my BMX race bike. thank you
