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.
Strong like bull, light like carbon. Every CARBON TUNED part is designed with a distinct style of riding in mind. By selectively layering woven carbon fiber at high-stress points and using unidirectional fiber throughout, SRAM creates components that yield a remarkable level of strength and durability-while remaining lightweight and responsive.
DUB™ technology features a better-engineered bottom bracket and a new spindle design. Together, these allow for a more uniform approach to bottom bracket fitment, better sealing against contamination and forward and backward compatibility. Now everyone can benefit from a new measure of durability.
