Hollowtech II design uses a wide bearing placement to maximize stiffness while keeping weight to a minimum.
HollowGlide hollow outer chainring reduces weight, increases strength and enhances stiffness of the entire crankset by 20% for even more shifting power
Wider gear range accommodates most cycling situations and offers less chain touch in the small/small combination
Individually machined chainring teeth improve chain contact for greater shifting performance
Improved bottom bracket seals reduce contamination and friction
