Update
Shimano's new XTR 10-speed Dyna-Sys cassette combines performance-enhancing stiffness with light weight, consistently smooth shifting and trail-tested durability to meet the evolving needs of today's mountain bike riders. Specifically designed for optimized performance with the mountain bike-specific HG-X chain and the new XTR Shadow rear derailleur, the XTR 10-speed cassette delivers outstanding shifting performance no matter how rough or rugged the off-road conditions.
  • Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load
  • Three-piece spider provides stiffness under load
  • Close-ratio gearing permits finer control of cadence for more efficient energy transfer
  • Five largest cogs are made from titanium to reduce weight
  • Sprockets are cut away and drilled to reduce weight without sacrificing rigidity
  • Nickel-plated finish is hard-wearing and resists corrosion
  • Includes alloy lockring
