We 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 our 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.
Eagle technology represents our newest 1x drivetrain technology. Eagle is a lighter, simpler, more durable, and easier to use drivetrain. Eagle features all-new 1x components, engineered for even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also provides an expanded gear range of 500%, which is equal to 2x11 drivetrains.
The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
