Praxxis crankcase for GXP cranksets.

Fits BB30 and PF30 frames.

30mm axles.

Screwed together inside the frame so it holds better.

At the end of the threaded piece, there is a rubber sleeve that is squeezed out when the box is clamped together, which creates a better fit and ensures that it sits firmly.

To install this crankcase, you will need a Praxxis M30 tool.
