Since their inception Praxis Works has been producing components to fit specific niches in the cycling industry. With the introduction of forged aluminum cranks we are seeing a slew of bottom brackets to go along with them. With their focus on durability over weight many riders are choosing Praxis bottom brackets over other aftermarket choices. Available in the most popular bottom bracket standards Praxis makes an option to fit almost any frame. Replace your old worn out bottom bracket or upgrade your existing BB with a Praxis Works Shimano Bottom Bracket for miles of friction free spinning and peace of mind.

Praxis Shimano Bottom Bracket is designed to work with a 24 mm / 24 mm spindle crank. Compatibility is listed below.



The Praxis M24 / GXP Bottom Bracket marked PF30/BB30 comes with a sleeve to fit PF30 frames. The sleeve will need to be press fit into the frame before threading in the BB30 converter. For a BB30 frame the sleeve can simply be discarded and the BB30 adaptor installed. The shape of the conversion bottom bracket allows almost any wire to pass over the shell of the BB in most all frames. The holes in the shell are simply for weight savings and should not be used for wire routing. If you end up using these as a last resort make sure to protect your wiring from the spinning axle.
