The M30 bottom bracket from Praxis Works is specially designed to accommodate the Praxis-designed Zayante cranks. With a stepped 30 to 28 mm spindle, the crank requires the M30 bottom bracket to be correctly adapted to the frame's bottom bracket shell. Taking advantage of Praxis designed “wide stance” technology, the Zayante crank and M30 bottom bracket push the cartridge bearings out as far as possible to create a solid platform for pedaling torque. In the case of BSA, BB30, PF30, and OSBB bottom bracket shells, the bearings are placed in cups completely outside of the frame, avoiding potential issues with frame tolerances. The result is a noise-free, efficient system with long service life.

The M30 is currently available for BSA English threaded, BB86/92(BB90/DH104.5/DH107), BB30/PF30, BB386 EVO, BBRight and T47 bottom brackets. The BSA version uses a straightforward design with two threaded bearing cups. The BB30/PF30 and OSBB version, similar in design to Praxis' conversion BBs, draws its strength from a threaded design that practically eliminates the shortcomings of press fit specs. By having the drive side cup thread into a tapered collet, the bottom bracket expands slightly inside the shell, thus creating a more ideal fit while simultaneously preventing the cups from walking or wobbling out of the frame. Both the BB86/92 and BB386 EVO bottom brackets use a standard press-fit design to accommodate their respective frame standards. The T47 External bearing cups can be used on either a 68 or 73mm threaded frame while the Internal version is used with an 85.5mm width frame. 

Praxis M30 threaded bottom brackets require the M30 BB Tool to be correctly installed, while the press-fit versions should be installed using a good quality bearing press.
