Cassette. With its wider-range 11-34T 10-speed HG cassette, the Shimano Deore XT M771 10-speed cassette helps you climb farther in your primary driving gear--the 32-tooth chainring. Long after other riders have blown up or bailed, you'll be taking advantage of more efficient gearing and full traction with a Dyna-Sys-inspired smile lighting up your face.
- 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
- Six largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity
- Sprockets are precisely cut and drilled to minimize weight without sacrificing strength and rigidity
- Chrome-plated finish is hard-wearing and corrosion-resistant.
