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 M24 / GXP Bottom Bracket for miles of friction free spinning and peace of mind.

Praxis M24 / GXP Bottom Bracket is designed to work with a 24mm to 22mm stepped spindle crank. Praxis M24 threaded bottom brackets use an older style 16-notch BB Tool to be correctly installed, while the BB86 should be installed using a good quality bearing press. Compatibility is listed below. 

PF30 / BB30 Compatibility

The Praxis Bottom Bracket Conversions marked PF30/BB30 come 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.
