Check out the new X-DOME™ Eagle™ cassette. The last dangling shred of the argument for a mountain bike front derailleur is now officially dead. Designed for use with our tried and trusted XD™ driver body, this 12-speed, 10- to 50-tooth cassette offers a 500 percent optimal gear range while weighing significantly less than 2x systems. It features the X-DOME™ architecture, which independent tests have concluded produces the most powerful cassettes on the market. New shifting features improve both internal and external shifting, as well as chain retention. This cassette perfectly matches X-DOME™ Eagle AXS™-enabled components in performance and color.
