Sram's Powerdome X design serves as the basis for the cross-specific sprocket set: the eight middle sprockets are manufactured on a single block of tool steel and are therefore designed to combine rigidity and light weight. Elastomers are located between these sprockets to provide vibration and noise damping.

Ready for "more pressure"
To ensure undiminished propulsion on muddy trails, the new Cross cassette differs from the familiar road cassettes from Sram: With large cut-outs on all sprockets, this cassette offers better resistance to dirt. Dirt, mud and water should be able to drain away better. Katie Compton, the US cross bike champion, says that the cassette is perfect for use in the Belgian mud.

Perhaps also as a Christmas tree ornament
The cassette weighs 159 grams on the rear wheel and is available with ten gears in a 12-27 ratio. With this range, mountain bikers could also enjoy it on a road bike. Initial availability is indicated by the manufacturer as December 2012.
