Shimano SLX HG81 10 Speed Cassette
The addition of a massive 36 tooth cog is one of the key features of Shimano's new 10 speed Dyna-Sys range of drive trains. The big advantage to the 36 tooth cassette is that you'll be able to stay in your middle and big rings longer meaning that you'll ultimately be shifting less. Who would have ever thought more gears would equal less shifting.
the 36t is awesome on my 2x10 29er. saviour on the uphill.
Good set of gears, can't find anything wrong with them, and good on the wallet as well
