Sram: FREEDOM Take a quick look at the new X-DOME™ Eagle™ cassette. The last dangling shred of an argument in favor of a mountain bike front derailleur is now officially dead. Designed for use with our proven, reliable XD™ driver body, this 12-speed, 10- to 50-tooth cassette offers an optimal 500-percent gear range at a considerably lighter weight than 2x systems. It carries with it the X-DOME™ architecture, which, independent tests have concluded, yields the strongest cassettes on the market. New shifting characteristics improve both, inboard and outboard shifting, as well as chain retention. This cassette matches up perfectly in performance and color to X01 Eagle AXS™ enabled componentry.THINGS TO REMEMBERNew Polar Grey 50t colorway is perfectly matched to work with X01 Eagle AXS™SRAM’s cassette manufacturing technology provides the greatest durability and lightest weightAll-new shifting features create a smoother, quieter system with enhanced inboard and outboard shift performanceXD™ driver body compatible10-50t: 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50 SPECIFICATIONSSpeed (CS): 12sGearing: 10-50tCog finish (Cassette): Polar GreyTechnology (Cassette): XGCog sizes: 10-50t:10,12,14,16,18,21,24,28,32,36,42,50
