Shimano Dura-Ace 7800 10-speed cassettes feature a superior surface treatment that has been applied to the titanium sprockets to 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 compared to the 9-speed CS-7700 sprocket. The CS-7800 sprocket is also compatible with the 9-speed freehub because it is designed to have nearly the same width.
