Shimano Dura-Ace FC-R9100
Shimano Dura-Ace FC-R9100
The Shimano Dura-Ace FC-R9100 remains one of the most iconic and beloved 11-speed cranksets ever produced. Setting the benchmark for mechanical shifting performance, it utilizes Shimano’s signature asymmetric 4-arm bolt pattern and a widened crank arm for maximum stiffness where the pedal stroke requires it most. Exceptionally light and brilliantly engineered, the R9100 is the ultimate upgrade for riders running high-end 11-speed mechanical or Di2 systems who want professional-grade power transfer and classic Dura-Ace aesthetics.
