This Wheels Manufacturing bottom bracket converts a PF30 frame shell to outboard bearings for 24mm Shimano and FSA cranks, with no adapter required.

  • Enduro ABEC 5 angular contact bearings - every ball engaged, spreading force over a larger area to cut friction and wear
  • Dual silicone seals keep contamination out for longer bearing life
  • Black anodised, machined aluminium cups
  • Made in the USA
  • Weighs 153g

Fits Shimano and FSA 24mm cranks

Built for current 24mm Shimano and FSA crank spindles. Wheels Manufacturing also lists a 24/22mm version for SRAM and Truvativ cranks - check your crank's spindle diameter before ordering.

Compatibility & fit

Fits PF30 frame shells 68-73mm wide with a 46mm bottom bracket shell inner diameter. The Tune workshop can press this in with the correct drift.
