This bottom bracket fits the M30 spindle of Praxis and Infocrank on a BB30 frame.

The set consists of our BB30-386 bottom bracket with road or cross bearings and a non-drive side reducer that will fit the 28mm stepdown of the 30mm Praxis spindle. This setup will space the bearings at maximum width, right next to the crank arms, to maximize your drive train stiffness and reduce bearing wear.

Choose road bearings for road bikes, cross bearings for mountain bikes and cyclocross.
