Wheels Manufacturing PF30 Bottom Bracket

Standard press-fit systems rely on a friction fit that can loosen over time, leading to movement and noise. This design uses two machined aluminum cups that thread together, locking the unit securely into your frame to eliminate that play and silence your ride.

This unit is designed specifically for PF30 and Specialized Carbon OSBB shells with a 46mm diameter. It accommodates shell widths ranging from 61mm to 83mm and is compatible with 30mm spindle cranksets.

The bearings are fully serviceable. The system is designed for straightforward maintenance, allowing you to easily replace the bearings when they eventually wear out rather than discarding the entire bottom bracket.

No, this specific model comes equipped with ABEC-3 steel bearings. These offer a reliable balance of durability and performance for most riding conditions.

You will need a bottom bracket tool with a 48.5mm x 16 notch interface to install and tighten the threaded cups. It is a standard interface used by many high-quality bottom bracket tools.

Moving the bearings outboard creates a wider, more stable platform for your 30mm spindle crankset. This increased support enhances drivetrain stiffness and helps extend the overall lifespan of the bearings.
