Praxis Works M30 THRU MTB BB30 / PF30 Bottom Bracket

Suited for many cranks: the M30 THRU BB30/PF30 73 mm MTB bottom bracket from Praxis Works

The Praxis Works M30 THRU BB30/PF30 MTB bottom bracket allows you to install the LYFT MTB crank from Praxis Works on 73 mm-wide BB30 or Pressfit 30 MTB frames. It can also be used for cranks from other manufacturers, such as Race Face (Cinch), Rotor (Rex) and Cane Creek (eeWings). In contrast to M30 technology, the M30 THRU system uses a 30 mm bearing on the drive side as well as a 30 mm bearing on the non-drive side.

Technology:

Practice Collet
Patented Praxis Works technology not only neutralizes all tolerances from frame manufacturers, but also guarantees an increased service life. In Praxis Collet bottom brackets, the non-drive side is pressed in and then the drive side is screwed into it. When screwed together, the bearing expands to a defined end position, which corresponds to the respective press fit, and sits tight without creaking. Additionally, an orange elastomer rubber ring is compressed in the drive direction, which in turn expands towards the frame, thereby jamming the bearing once again. The elastomer material compensates for tolerances while simultaneously muffling any cracking noises.
