Lightweight yet rigid design is highly durable and incredibly strong
HollowTech II bottom brackets bearings are mounted outboard of the frame, increasing there diameter and placing them more widely apart; this dramatically changes the load on the bearings increasing rigidity and bearing service life
We recommend that this bottom bracket is initially installed by a bike shop to ensure perfect bottom bracket facing and fit
Comes complete with chain ring fixing bolts and nuts
For use with a single chainring in a choice of sizes from 34 tooth to 46 tooth
