Look no further than Shimano’s Dyna-Sys CS-HG81 Cassette for mega-smooth shifting and ultra-close gear ratios. With a tighter gear spread, you’ll spend less time searching for the perfect cadence and more time cruising up hills—and with the available 11-36T cassette, you won’t have to visit granny as much either.

Great mid-level cassette that works great!

While I prefer the shifting of the Sram shifter and rear d the Shimano Dyna Sys cassette and XT chain work great and are very affordable. While the XT isn't light enough to justify the upgrade in my opinion I will totally get an XTR cassette when I can afford it.

Smooth, strong and quiet

The shifting on the new Dyna-Sys cassette is amazing. 10 speed specific shift geometry ensures a clean shift every time, and you'll never get any "skating." This cassette is much quieter than its one-piece counter part. I like the 36 tooth big cog option.
