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, 10-50t or 10-52t tooth cassette offers an optimal 500/520 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.

• Stronger riders can increase chainring size for speed, without sacrificing climbing.
• Eagle Colorsystem lets the cassette and chain express the look of the bike. Available in Rainbow, Gold and Copper.
• Provides a massive 500 & 520-percent gear range.
