Technology:
M30
Praxis Works M30 bottom brackets are only suitable for use with Praxis Works M30 cranks. The M30 axle corresponds to a kind of "oversize GXP". It is 30 mm thick and reduced to 28 mm on the left end to fit the non-drive side bearings. A shaft washer is used at the drive side to provide preload and a 30 mm bearing, which is opposed by a 28 mm bearing at the non-drive side. M30 combines the advantages of wide bearings with the benefits of a sturdy 30 mm axle. This enables a secure fit and better power transmission.
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.
