WHEELS Mfg PF30 Bottom Bracket

This unit is designed for frames with a 46mm bottom bracket shell inner diameter. It is compatible with PF30, PF30A, 386EVO, Specialized Carbon OSBB, and BBRight standards, covering shell widths from 61mm to 86.5mm.

This bottom bracket is specifically engineered for cranksets with a 30mm spindle diameter. Please verify your crank spindle size before purchasing, as it will not fit standard 24mm spindles.

The primary benefit is the precision-machined aluminum cup construction, which is significantly more durable than many stock plastic or composite cups. This rigid design helps eliminate the common creaking issues often found in press-fit systems by providing a more stable interface.

Yes, the bearings are designed to be replaceable. This allows you to service the bottom bracket and extend its lifespan without needing to replace the entire unit when the bearings eventually wear out.

Yes, because it is a press-fit system, you will need a dedicated press tool to install the cups into your frame. We recommend using a high-quality bearing press to ensure the cups are seated perfectly straight to avoid premature wear.
