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 M30 Thru Bottom Bracket for miles of friction free spinning and peace of mind. For installing the BSA and BB30/PF30 bottom brackets the M30 BB Tool is required.

The M30 Thru Bottom Bracket has two 30mm I.D. bearings and is intended for use with the Praxis Works LYFT Crank but will also pair with other 30mm spindle cranks on the market such as the Race Face Cinch and Rotor REX1 cranks.

If you’re looking to pair your existing Praxis Works Cadet or Girder Cranks check out the M30 Bottom Bracket designed to work with the Praxis 30mm to 28mm stepped spindle.

Praxis M30 threaded bottom brackets require the M30 BB Tool to be correctly installed. The T47 Internal requires the T47 I.B tool, while the press-fit versions should be installed using a good quality bearing press. Compatibility is listed below.
