Shimano CS-R9100 Dura Ace 11Spd Cassette 11-28T

Superlight 11-speed cassettes with a rigid carbon and alloy carrier providing smooth, fast and reliable shifting all of the time, even under heavy load!

Close ratio gearing is now possible thanks to the introduction of 11-speed ensuring optimum use of power through finer cadence control.

To reduce weight in the cassette without sacrificing strength Shimano have produced the 5 largest sprockets using titanium, wih a nickel plated finish to offer greater resistance from corrosion.

Pair the Shimano CS-R9100 11-speed cassette with Shimano Dura-Ace chain, chainset, derailleurs and shifter levers for optimum performance.

For those tough hilly days Shimano has now produced the Dura-Ace cassette in a 11-30t version.
