  • Three alloy carriers and 5 titanium sprockets make this Shimano's lightest 10-speed Dyna-Sys MTB cassette
  • 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
  • Three separate lightweight alloy carriers reduce weight and increased stiffness giving more precise faster shifts
  • Five largest sprockets are made from titanium to reduce weight without sacrificing strength
  • Sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity
  • Nickel-plated finish offers hard wearing resistance to corrosion
  • Alloy cassette lockring
  • For 10-speed HG-X MTB chains
  • Average weight 255 g
  • Ratio 11-36 10 speed


  • HG-X Chain uses a directional design with specifically shaped inner and outer plates to optimise shifting over the chainset and cassette
  • Outer plate design has been developed to reduce the chance of chain suck
  • The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near silent running
  • Hollow link pins offer great weight savings
  • Durability is assured through a chromising treatment on link pins, and the heat treatment of rollers, pins, and plates
  • Open design of inner links increase mud shedding ability
  • Chain is optimised for Shimano 10-speed HG-X MTB drivetrains only
  • Zinc-alloy silver finish offers the longest lasting and best resistance to corrosion
  • 259 grams

General information about our shipping
I have purchased one of these before. They are properly the best in the market. I do a lot of mountain biking and the cassette seems to last for a long time. I'd highly recommend using XTR items
