Enhancing the Ultegra lineup is the new 6700 series crankset. Drawing technology from the race proven, top of the line Dura Ace series cranks, Shimano spared no limit making the Ultegra just as technologically advanced, while saving you a few bucks. New to the cranks are a hollow forged outer chainring that increases rigidity of the chainring and Hollowtech II arms that optimize balance between lightweight and stiffness ultimately improving performance to a pro level. A slight increase in distance between inner and outer rings effectively eliminates chain run in extreme chain line situations. Bottom bracket cups sold separately
