Shimano Dura-Ace 9100 Chainset - HollowTech II 55/42T

The new Shimano Dura-Ace 9100 Chainset - HollowTech II 55/42T is more than just a change of appearance for Shimano's pro-level chainset. Designed to optimise power transfer, this crankset is seven grams lighter than the previous Dura-Ace iteration. This reduction of weight does not come at the expense of stiffness as it still boasts optimal stiffness and efficiency with a newly designed crank arm. The four arm construction boasts strength and aerodynamic efficiency.

HollowGlide technology on the chainrings improve shifting crispness and smoothness with individually designed tooth profiles. The tooth profile also helps to fit a wider gear pitch.
