Product Description

SRAM built the incredible new XX1 Eagle drivetrain to work quietly, intuitively, precisely and perfectly. Whether you’re an hour and twelve minutes into a World Cup XC or, just about to hit the top of Pearl Pass - XX1 Eagle is ready for that and every place in between. This cross-country-optimized drivetrain combines the newest generation of SRAM 1x drivetrain technological advancements with lightweight materials. With a greater gear range of 500-percent, XX1 Eagle gives you smoother, more precise shifts with greater durability for long lasting performance so you can spend more time in the gear you want. XX1 Eagle just rewrote the rules of freedom.

XX1 Eagle Trigger Shifter
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.

XX1 Eagle Rear Derailleur
This new derailleur not only answers the Eagle drivetrain’s need for greater capacity, but is also the next evolution of the 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. The 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.

XX1 Eagle DUB Crankset
True competitors are always looking for a performance advantage - a relentless pursuit of equipment that is lighter, stiffer, stronger and more durable. To create the best drivetrain possible, SRAM re-examined and re-engineered their crankset design. The all-new XX1 Eagle Carbon Tuned crankset is their lightest, stiffest and strongest to date. DUB technology enhances this by simplifying the relationship of the spindle to the bottom bracket, and redefining the measure of durability. DUB-powered cranksets mean simplicity, compatibility and durability.

XG-1295 Eagle Cassette
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 the 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.

XX1 Eagle Chain
It might look normal from the outside, but the engineering inside this incredible new chain design that makes possible a gear range previously found only in 2-chainring drivetrains. And it’s also the biggest contributor to the Eagle drivetrain’s ultra-smooth, precise, durable and quiet performance. The Eagle chain’s links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. Hard Chrome technology extends the chain’s optimal performance life, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.
