Threaded BB with splined ISCG-05 interface

By using a spline on the driveside of our threaded BB shells that interfaces with our ISCG-05 plates enables riders to rotate the chainguide mount to work optimally with any chainguide. It also means that if you were to smash a chainguide on a rock hard enough to damage the mounting threads, that the ISCG plate can be easy replaced without the need to replace a whole front triangle.

A very simple detail… but the devil is in the details!
