Wheels Manufacturing PressFit 30 Bottom Bracket

Standard press-fit systems rely on a friction fit that can loosen over time, leading to movement and noise. This unit threads the two cups together, locking them securely against the frame shell to eliminate the micro-movements that cause creaking.

This bottom bracket is compatible with frames featuring PF30 or 386 EVO standards with a 46mm shell diameter. It is designed to fit shell widths of 68mm and 73mm.

Ceramic bearings are harder and rounder than standard steel, which results in significantly lower friction and smoother rotation. For most riders, this translates to a more efficient pedal stroke and a noticeable improvement in drivetrain feel.

No, the bearings in this specific model are not designed to be serviceable. If the bearings eventually wear out, the entire cup assembly will need to be replaced.

Yes, because this is a threaded system, you will need a specific bottom bracket wrench or socket compatible with Wheels Manufacturing threaded cups to tighten the two halves together properly.
