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.

• SRAM’s cassette manufacturing technology provides the greatest durability and lightest weight
• All-new shifting features create a smoother, quieter system with enhanced inboard and outboard shift performance
• XD™ driver body compatible
• 10, 12, 14, 16, 18, 21, 24, 28, 32, 36, 42, 50
