Shimano Dura-Ace 9100 11-Speed Cassette 11-28T

Smooth shifting and a low weight; the Shimano Dura-Ace 9100 11-Speed Cassette 11-28T is Shimano’s top-of-the-line cassette for a reason. Five titanium sprockets and a carbon fibre reinforced polymer and alloy spider ensure longevity; a low weight and pro-level performance.
