Shimano Dura-Ace 9100 11-Speed Cassette 11-30T

Smooth and reliable shifting with a wide range of gears that are perfect for climbing; the Shimano Dura-Ace 9100 11-Speed Cassette 11-30T is Shimano’s pro-level cassette for a reason. A carbon fibre reinforced polymer spider and five titanium sprockets keep the weight low with ultra-smooth shifting.
