Shimano Dura Ace 10-Speed Cassette

Features

• A superior surface treatment has been applied to the titanium sprockets that increase durability by approximately 30%
• The sprocket width has been slightly reduced, to achieve chain compatibility and only increases the overall weight of the cassette sprocket by 17 grams more compared to the 9-speed CS-7700 sprocket
• The CS-7800 Sprocket is compatible with the 9-speed freehub because it is designed to have nearly the same width
• Weight: 163 grams
