Sram: FREEDOMTake 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. THINGS TO REMEMBEREagle™ represents our newest 1x drivetrain technologiesEagle™ is a lighter, tougher, quieter, more durable and more preciseEagle™ features all-new 1x components, engineered for even greater durability and performanceEagle™ has a significant weight advantage over other drivetrainsEagle™ technology allows an expanded, optimum, 500-percent gear range — a 20-percent increase over our other 1x drivetrainsEagle™ is a complete drivetrain system that was developed to be an integrated high-performance ecosystem. The engineering and testing that went into the development provide for maximum performance, safety, and long-term durability to ensure a great consumer ride experience. We guarantee this performance when Eagle™ drivetrains are used as a complete ecosystem.
