Shimano Dura-Ace 9100 Chainset - HollowTech II 54/42T
The new Shimano Dura-Ace 9100 Chainset - HollowTech II 54/42T 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 improves shifting crispness and smoothness with individually designed tooth profiles. The tooth profile also helps to fit a wider gear pitch.
