Shimano Deore XT CS-M8100 12-speed 10-51T cassette.

If you want to cover as wide a range as possible, then the 10-51 option is the best choice. Of course, all CS-M8100-12 cassettes have the Shimano Hyperglide+ technology for high shifting speed, precision and smoothness when upshifting and downshifting. Also the noise is thus minimized. Contributing to the weight reduction, robustness and durability is the spider construction made of aluminum and the manufacture of the two largest sprockets also made of aluminum.
