Shimano 9100 Cassette 11 30T

Shimano 9100 Cassette 11 30T. The Shimano Dura Ace 9100 drivetrain continues to serenade cyclists with its Rider Tuned anthem. The Dura Ace 9100 cassette was designed by Shimano based on direct rider feedback. Though the differences between the 9000 and 9100 cassettes are subtle, they're significant. With the new additions to the Shimano Dura Ace 9100 series comes the exciting inclusion of the 1130T cassette, which is the largest cassette ever offered at a Dura Ace level. Its expansion of gearing options and rigid tooth profile for incredibly smooth shifting are what set this cassette a part from others. Not only does it feature a CFRP and alloy spider arm, it also includes 5 titanium sprockets for lightweight performance. The 1130T cassette also features a tool free joining link for added convenience.
