PressFit 30 (46mm) bottom bracket. Once pressed into your frame, you can mount any threaded-based shell in the standard reverse thread (BSA/BSC). Comes with bushings and spacers. 48g.

If your bike creaks when you put a lot of pressure on the pedals, or if the movement of the crankset has become loose or lost fluid, it’s time to replace your bottom bracket. Like all parts of your bike, the bottom bracket and its bearings are subject to wear.

Replacing it is a straightforward operation if you are well-prepared. However, the variety of standards for bearings, bottom brackets, and frames can be overwhelming. We want to help you navigate through this complexity. The bottom bracket is the interface between your crankset and your frame, so the first step is to identify which crankset is supposed to fit which frame.
