Description of praxis works Conversion MTB Bottom Bracket 73mm for Shimano Cranks on BB30/PF30/OSBB - PF46/BB42-73-24

High quality BB30, PF30 and Specialized OSBB (73x46mm case measurements) MTB bottom bracket with 73 mm width for integrated 24 mm Shimano hollow axle.

Expanding R-Collet: After installation of the bottom bracket the rubber will try to expand again and puts pressure towards the bottom bracket cups. This orange expanding rubber collet holds the unit snug and silent in your frame.

Conversion BB - This industry leading conversion BB is a full proper bottom bracket for many BB housings. praxis works patent pending design keeps the cartridge bearings outboard of the frame right on spec for greater rigidity and free of frame/c-clip tolerance issues that other systems deal with. Simply press in the longer Non Drive Cup, then the shorter drive cup threads into it. As the Drive cup threads in, their trademark Praxis Collet system expands to a precise machined limit evenly dispersing pressure for a super tight fit.
With both cups connected and the collet set exactly to spec, there is no chance the bearings can come out of alignment or walk out of the frame. This design also uses a compressible o-ring on the non-drive side cup to compensate for frame shell width discrepancies.
