This Wheels Manufacturing bottom bracket fits 30mm spindle cranksets, including RaceFace Cinch, into PF30 frames with outboard bearings.

Highlights

  • Enduro ABEC-3 bearings
  • Two machined aluminium cups thread together, keeping the bottom bracket stable in the frame
  • Increases bearing life and simplifies maintenance - no more creaking, smoother operation, quick bearing replacement
  • 48.5mm, 16-notch tool pattern

Spindle length matters

Spindle length must be 103mm or longer in a 68mm wide shell, or 108mm or longer in a 73mm wide shell.

Compatibility & fit

Fits PF30 and Specialized Carbon OSBB shells 61-83mm wide with a 46mm bottom bracket shell inner diameter, for 30mm spindle cranks. A 61mm Specialized Carbon OSBB shell needs an additional 3.5mm cup spacer, sold separately. Over-bearing width is 89mm in a 68mm wide shell.

Wheels Manufacturing backs this bottom bracket with a 1-year warranty against manufacturing defects, plus 30-day returns on unused, unopened stock bought direct from Wheels Manufacturing. Wear items such as bearings, seals and spacers aren't covered under the defect warranty. For warranty support, return the product to Tune Cycles and we'll manage the claim with Wheels Manufacturing's Australian distributor.
