Kassett Shimano XT M771-10s 11-36T
For their Dyna-Sys 10-speed system, Shimano added another cog to their venerable XT level cassette. So like the previous 9-speed versions, the CS-M771-10 XT Cassette has the same Hyperglide tooth and ramp shapes to help the chain move effortlessly across its range.
The XT 10-Speed Cassette uses plated steel cogs for superior durability, but that doesn´t mean that it weighs a ton. The largest six cogs are minimal in design and are pinned to two lightweight alloy spiders -- three cogs for each spider. The four smallest cogs go on separately, and the whole batch is secured with a sleek alloy lockring. This cassette is compatible with Shimano´s Dyna-Sys 10-Speed shifter and rear derailleur.
