Riders with a PF30 frame running a SRAM or Truvativ GXP crank who want a quieter, more durable bottom bracket.
PF30 frames have a big 46 mm shell, which can creak and wear bearings when cups are simply pressed in. The Wheels Manufacturing PF30 Outboard bottom bracket uses two machined aluminium cups that thread together inside the shell, holding everything square and tight.
This version suits SRAM and Truvativ GXP cranks with their stepped 24/22 mm spindle, fitting them into PF30 frames with no adapters. Expect less creaking, smoother running and longer bearing life, with quick bearing replacement when it is due.
The box includes dust seals, spindle spacers, 46 mm cup spacers and a wave washer to get the spacing and preload spot on.
No more creaks
Thread-together cups keep the bottom bracket stable in the shell.
GXP direct fit
24/22 mm SRAM GXP cranks into PF30 frames without adapters.
Full spacer kit
Spindle spacers, cup spacers and a wave washer included.

Thread-together design
The two cups screw into each other inside the shell, keeping the bearings aligned and the unit stable for a quieter, longer-lasting bottom bracket.
Great for
Maybe not for
For PF30 shells with a 46 mm inside diameter and SRAM GXP 24/22 mm spindles. Not for DUB cranks.
Mind the GXP side
GXP spindles step down to 22 mm on the non-drive side, so the bearings are sided. Keep track of which cup goes where, use the supplied spacers to set chainline, and finish with the wave washer for preload. We are happy to fit it for you.
