Shimano Dura-Ace R9100 11-Speed Cassette

The Shimano Dura-Ace 9100 11-speed cassette offers high end, pro-level shifting performance, with a super lightweight construction. This cassette has been designed for the most optimised shifting experience possible, with Shimano Hyperglide technology.

Close ratio gearing allows a more efficient use of energy through finer cadence control. To keep the weight to a minimum, the largest 5 sprockets are mode from titanium and have been extensively cut away and drilled.
