Praxis - Conversion BB for SRAM/GXP MTB

Bottom Brackets

Product Details

PRAXIS - CONVERSION BOTTOM BRACKET FOR SRAM/GXP MTB

THIS IS NOT AN “ADAPTOR”

Our new patent pending elastomer collet 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 with orange elastomer threads into.  As the drive cup threads in, the orange elastomer collet expands to a precise machined limit evenly dispersing pressure in your frame shell for a super snug fit.

This Conversion BB is for installing a Praxis M24 or SRAM GXP steel spindle crank in either BB30 or PF30 MTN frame. This bottom bracket is made of lightweight and durable aluminum with long lasting sealed cartridge bearings.

New updated design with Rubber expanding collet.
