Product Details
Match your riding style as well as your chosen terrain with Shimano's lightweight Titanium Dura Ace CS-R9100 11-Speed Cassette. New combinations of gearing options have been added including expanded choices for gearing appropriate to wheels, climbers, and the punchers who demand the best of both worlds, but the cassette's feathery construction combination of titanium and nickel-plated steel cogs (along with alloy and carbon carrier) remain tried, true and unaltered. The CS-R9100 Shimano 11-30T cassette with hyper-glide is most definitely a welcome addition to the cassette line up and provides the Dura Ace R9100 series, on the back end of the drivetrain, with a wider range of graduation, along with fast, accurate and smooth shifting in all situations. No matter if, you are up shifting or down shifting, the Dura Ace R9100 cassette stands out above all others through its' reliable and easy shifts.. Smooth running and reliable 30T, 11SP Cassette
