Super lightweight 10-speed cassette with a rigid alloy carrier for excellent shifting even under the most demanding gear changes. Featuring four titanium cogs, the new Dura-Ace 7900 cogset has further improved shifting quality by creating a more rigid aluminum carrier unit along with a re-engineered tooth profile. Shimano also successfully reduced the weight of the rear wheel assembly by 10 grams.
Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load
Close ratio gearing allows a more efficient use of energy through finer cadence control
Largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity
4 largest sprockets are made from titanium to reduce weight without sacrificing strength
Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity
Nickel-plated finish offers hard wearing resistance to corrosion
