SHIMANO Dura-Ace FC-R9100 Hollowtech II Black Crankset 2x11-Speed

SHIMANO Dura-Ace FC-R9100 Hollowtech II Black Crankset 2x11-Speed

The R9100 series crankset achieves the ultimate in optimal power transfer. It does this through its broader Hollowtech II arm and a more reinforced outer chainring on its unique asymmetrical four-arm spider construction.

The new R9100 cranks set the highest standards for stiffness and lightness. The drivetrain is perfectly balanced for improved performance. All components are part of an integrated system for optimum power transfer, including the vast array of gearing choices to perfectly match your riding style and needs.

Repeatedly tested for maximum efficiency on all terrains, under all conditions.
