WHEELS Mfg PF30 Threaded Angular Contact Bottom Bracket

Standard press-fit systems rely on a friction fit that can loosen over time, leading to movement and noise. This unit uses two machined aluminum cups that thread together inside the frame, creating a secure, rigid connection that prevents the shifting and micro-movements responsible for creaking.

This model is compatible with PF30, PF30A, BBRight, and Specialized Carbon OSBB frame interfaces. It is designed for frames with a 46mm bottom bracket shell inner diameter and shell widths ranging from 61mm to 79mm.

Angular contact bearings are designed to handle both radial and axial loads simultaneously. This makes them more durable and smoother under the side-loading forces typically applied during pedaling, resulting in a more efficient and longer-lasting drivetrain.

Yes, the system is designed for straightforward maintenance. Because the cups are threaded and removable, you can easily service or replace the bearings without needing to press out the entire assembly from your frame.

Yes, this bottom bracket is specifically engineered to accommodate cranksets with a 30mm spindle diameter.
