Wheels Manufacturing PF30 Threaded Bottom Bracket

Standard press-fit bottom brackets often develop play over time, which leads to that familiar creaking sound. This unit uses two machined aluminum cups that thread together inside the frame, locking them securely in place and eliminating the movement that causes noise.

This bottom bracket is designed for frames with a 46mm shell diameter and widths ranging from 61mm to 79mm. It is compatible with PF30, Specialized Carbon OSBB, and BBRight standards.

This specific model is designed for cranksets with a 30mm spindle diameter, specifically those using the BB30 interface.

The bearings are fully serviceable. Because the cups thread together rather than being pressed in, you can easily remove and replace the Enduro ZERØ ceramic hybrid bearings when they eventually wear out, extending the life of the unit.

Yes, you will need a bottom bracket tool with a 16-notch, 48.5mm outer diameter interface to tighten the cups securely. It is the same standard used for many external bearing bottom brackets.

The Enduro ZERØ ceramic hybrid bearings offer lower rolling resistance and increased durability compared to standard steel bearings. They provide a smoother feel under load and are generally more resistant to corrosion.
