The Dyna-Sys technology on the Shimano XT M771 cassette provides more efficient power transfer. The power of the rider is transferred more efficiently due to reduced chain tension, less need to change gear and improved continuous cadence due to a closer chainring combination on the chainset and wider cassette ratios. These points improve pedalling efficiency, give smoother and more comfortable front shifting while having less effect on pedal feedback when used on suspension bikes.
