Praxis Works Conversion Bottom Bracket
Designed precisely to SRAM bearing stance & chain line specs this Praxis Works Conversion Bottom Bracket is ideal for installing a Praxis M24 or SRAM GXP steel spindle crank in either BB30 or PF30 Mountain frame.

Praxis Rubber Expanding Collet
The Praxis Works GXP/ISIS2 SRAM MTB Conversion Bottom Bracket features a rubber expanding Collet design with "Collet" style, non-drive cup expansion for wiggle-free press. This greatly reduces the chances for creaking and other unwanted noises associated with the lesser “Band Aid/Spacer” type adaptors in the market. It also refines the fit of the BB inside the frame even better than the original Praxis collet. The Non-Drive O-Ring compensates for any frame width discrepancies.

Suits 73mm BB30 or PF30 Mountain Frames
This lightweight and durable bottom bracket is made of forged & machined, heat-treated 7075 T6 Aluminium with long lasting sealed cartridge bearings. It is suitable for 73mm BB30 or PF30 mountain frames and will work well with Praxis M24, SRAM/Truvativ/Quarq GXP2STEEL Spindle, also Oval Concepts 400 series MTN cranks.
