Pairs nicely with Next SL cranks.

The Race Face Cinch BB92 Bottom Bracket is an ingenious solution to fitting Race Face's Next SL crankset to your bike with a Shimano BB92 shell. Realizing the BB92 standard accommodates a 24-millimeter spindle, the engineering gurus at Race Face use 19 custom ball bearings to increase strength, which is essential since the jump to the Next SL Crankset's 30-millimeter spindle leaves less room for the bearing. And since less clearance could be detrimental to durability, the increase to 19 bearings ensures robust performance, without any sacrifice in overall strength. Moreover, it's filled with Phil Wood bearing grease for reduced friction. There's also a plastic inner sleeve to protect the bearings from the intrusion of outside moisture from working into the bottom bracket shell.

  • Shimano BB92 shell type
  • Accommodates 30mm crank spindles
  • Custom 19 retainer bearings
  • Bearings filled with Phil Wood grease
  • Includes protective inner sleeve

Rarely seen, never heard

  • Familiarity: I've put it through the wringer

Your bottom bracket should be something you rarely look at, and never hear. I've had 3 Cinch PF style BBs on varying bikes, and never had cause to look at them. Smooth and silent, just as a good bottom bracket should be.

Perfect for the job

Works just fine. Make sure your compatibility is correct before you order; frames have different BB shell sizes and compatibility for cranksets. Shoot me an email if you have any questions about compatibility, or if you're looking to build up a particular frame...I can always make sure you're matching it up correctly.

Fits the Mach 6

    Most important thing with a Bottom Bracket, make sure it fits your frame and crankset. This Race Face Cinch BB92 slipped right into my new Pivot Mach 6 and has worked great so far, my bike pedals like a machine.

    Big thanks to Joe Bolton in our Retail Store Bike Shop for getting my new Mach 6 put together. If you are ever in Salt Lake City definitely stop by our Retail Store to check out their bike selection and visit Joe (2607 S 3200 W, Suite A, West Valley UT 84119). Contact me with any questions about this BB, especially if you are interested in custom building a new mountain bike.

    Does what its supposed to

    • Familiarity: I've put it through the wringer

    The right bottom bracket for you if you have a Pressfit 92 bike (like a modern Giant, Trek, or Pivot) and want to run a Race Face Cinch Crankset (like Next SL, SIXC, Turbine, Atlas, or Aeffect). Presses into the shell easily and after a full season of riding has not had any creaks. Not compatible with any other crankset besides RF Cinch.
