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.
