The new Dura-Ace group boasts a variety of improvements, and the 10 speed cassette is no exception. Weighing in at just 173 grams (11-23 model), it boasts a new surface treatment that increases durability by approximately 30%. Thanks to the judicious use of titanium, it's also one of the lightest cassettes on the market.

Due to the decreased width of the sprockets, this cassette can be used on older 9 speed Dura-Ace freehubs, as well as the new 10 speed compatible hubs.
