Praxis - Conversion BB for Shimano MTB

Praxis Conversion Bottom Bracket for Shimano MTB

Lets you run a Shimano Hollowtech II steel spindle crank in a BB30 or PF30 mountain frame. It's a conversion bracket, not an adaptor, so the bearings stay outboard of the frame right on spec.

Key Features

• Elastomer collet: the orange drive cup threads in and the collet expands evenly for a snug fit in the shell
• Forged, machined, heat-treated 7075 T6 aluminium
• Steel Enduro 2437 bearings (a ceramic version also exists, check what we have in stock)
• Built to Shimano bearing stance and chainline

Specifications

• Fits: Shimano Hollowtech II steel spindle cranks only
• Frame: 73mm BB30 or PF30 mountain frames
• Not for BBRight, BB386EVO, BB86 or BB92 frames, and 68mm MTB shells aren't supported
• Chain guides: ISCG05 and seat-tube mounted are fine, ISCG03 is not
