Integrated design makes installation and adjustments easier than ever.
Precision bottom bracket bearings are spaced further apart, and are therefore more stable and longer lasting than conventional bottom brackets
Super-lightweight HollowTech II forged Duralumin crank arms - hollow design saves weight whilst increasing rigidity.
Easy to use splined bottom bracket spindle connection provides a rigid and secure interface between crank and spindle.
38-26T double set up ideally suited for all-mountain use in conjunction with 11-36T cassettes.
