SRAM XX1 EAGLE 12Spd Drivetrain

This new derailleur not only answers the Eagle™ drivetrain’s need for greater capacity, but is also the next evolution of our proven, 1x-specific X-HORIZON™ design. The larger, 14-tooth X-SYNC™ lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle’s overall smooth-pedaling feel. Our new, Type-3 ROLLER BEARING CLUTCH™ features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK™ has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle™ derailleur’s performance and overall durability.

Tucked neatly beneath your handlebars, the XX1 Eagle™ X-ACTUATION™ trigger shifter is the nerve center of the Eagle™ drivetrain. Its internal works have been updated to include a 12th gear, and improved to enhance trigger feel, precision and durability. Whether you’re 3 laps into your race or 150 days into your season, the XX1 Eagle™ trigger shifter is your faithful 1x touch point.

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.
