Shimano Dura Ace 9000 Cassette
Shimano's Dura-Ace 9000 11-speed cassette utilizes cogs that, with respect to width, are identical to 10-speed 7900 so there is no loss in cassette longevity with Shimano's latest top of the line offering. The cassette continues to make use of 5 titanium cogs to ensure the lightest possible weight, however, the Durace Ace 9000 cassette uses a composite spider as well as an alloy spider to decrease weight even further inspite of having an extra ring. With the tighter gear spacing afforded by the new 11-speed setup shifting occurs faster than ever!
