Description of praxis works Conversion Ceramic Road Bottom Bracket OSBB 61.5mm for Shimano Cranks on OSBB - PF46-61.5-24

Highquality ceramic OSBB bottom bracket with 61.5 mm width for Shimano cranks with integrated 24 mm hollow spindles. For Specialized OSBB Carbon frames with 46x61.5 mm inner shell.

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.
