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.
