Shimano XT M771-10 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?
Please Note:This cassette can only be used in conjunction with Shimano Dyna-Sys series components. Dyna-Sys was designed from the ground up to be used as one complete unit and parts from previous generations cannot be mixed and matched.
Great cassette. It may be a little heavier but it's the reliability time after time. Chain transfer from sprocket to sprocket is fairly smooth. The biggest appeal the cassette is it can take a beating from XC racing dust itself off and then go on a long trail ride with no problems.
Great looking, great running. Using it with an xt chain and derail. Raceface NW ring up front. Went with xt over slx in case I ever decided to try the 42 tooth conversion....slx can't handle it.
This to me is a no brainier upgrade to your bike. Increase performance and a notable weight difference between this and the deore cassette commonly used on mid level bikes.
