Praxis's BB30/PF30 conversion bottom brackets use a Delrin sleeve in PF30 frames. This is the replacement, handy if the original has gone missing or you are moving the BB to a different frame.

Which sleeve?

Pick the sleeve that matches your Praxis conversion BB and frame. The sleeve goes on for PF30 frames (46mm bore) and is left off for BB30 frames (42mm bore). Press-fit and collet bottom brackets need a press and the right cup tools; the Tune Cycles workshop can fit your BB as a separate workshop service.

Compatibility & fit

Only for Praxis conversion bottom brackets with the expanding collet: the BB30/PF30 versions of Praxis's M30, M30 THRU, M24/GXP and Shimano-fit BBs. It is not a sleeve for other brands' bottom brackets.
