Product Description

The Shimano Dura-Ace CS-7900 Cassette is lighter, more seamlessly integrated, and offers more options than ever before. Get that? More of everything, except weight. Ten grams lighter than the CS-7800, thanks to a lighter machined aluminum carrier unit. Stiffer than ever, with four titanium high gear cogs atop the six steel low gears. New tooth profiling and carrier interfacing improves shifting and drivetrain efficiency when mated with its matching Dura-Ace chain. And on the ratio side, more sizes mean you can choose a gearing ratio that's practically custom-fitted to your individual riding style. In short, the Dura-Ace CS-7900 is better than ever before, from every angle. Compatible with Shimano Dura-Ace RD-7900 and RD-7800 rear derailleurs, and Dura-Ace CN-7900 and CN-7801 chains. RD-7800 derailleur cannot accommodate 11-27 and 11-28 cassettes.
