Superb shifting smoothness, a low weight and a stiff and durable four arm HollowTech construction makes the new Shimano Dura-Ace 9100 Chainset - HollowTech II 55/42T a crankset fitting of Shimano's top-of-the-range Dura-Ace name.

The HollowGlide tooth profile boosts shifting smoothness while also reducing the threat of chain slippage.

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 improves shifting crispness and smoothness with individually designed tooth profiles. The tooth profile also helps to fit a wider gear pitch.
