    Praxis m30 bottom bracket

    Ive just got a Allez Sprint frame which has the Praxis cranks and M30 bottom bracket . Will my Sram Quarq cranks which are BB30 fit the Praxis bottom bracket or do i need a new BB30 bottom bracket ?

    What model Praxis crank? Look it up on the Praxis website to see what the BB is compatible with, or contact Praxis directly. They’re very responsive.

    There's a few different types of the M30, you have the conventional one.

    On one side it's 30mm and the other is 28mm. BB30 is 30mm on both sides.

    The M30 THRU version might work, but at that rate you can get any BSA30 Bottom Bracket.
    use a torque wrench

    No you don't need new one. The praxis BB fits general models well.
