Shimano's new XT M8000 11-speed cassette is the key to taking full advantage of the Dyna-Sys 11-speed system. This cassette is specifically designed with a wide gear combination and carefully balanced ratios for you to find that perfect gear on the trail. Through its carefully-calculated Rhythm Step gear progression, the XT M8000 Cassette decreases "shock" and lost power as you shift gears, ultimately delivering smoother and more precise gear changes.
By strategically constructing the cogset using a combination of steel and aluminum cogs and carriers, an optimal balance of light weight and durability is met. With Shimano’s CS-M8000 augmenting your steed, you’ll expand your range to take you to new trails never before possible. Whether you're a rowdy trail rider or an cross-country racer, the XT M8000 Cassette is ready for whatever you can throw at it.
