SRAM built the incredible 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.
LIGHTER. STIFFER. STRONGER.
True competitors are always looking for a performance advantage-a relentless pursuit of equipment that is lighter, stiffer and stronger. To create the best drivetrain possible, SRAM started with a completely re-engineered crankset design. The XX1 Eagle™ crankset is one of the lightest, stiffest and strongest on the market. A special hollow internal architecture, combined with SRAM's proprietary CARBON TUNED™ lay-up, allows to build a lightweight and ultra-energy-efficient crankset perfectly suited for the high-wattage output and smooth style of cross country riding and racing. Teamed up with an Eagle™ direct mount chainring, and as an integral part of the Eagle™ drivetrain. The DUB crank spindle, which can be universally used in all common bottom bracket shells, also increases rigidity. The bearing play will be fine tuned with an adjuster ring.
- crank-arm design optimized for cross-country and trail applications
- SRAM CARBON TUNED™ crank technology provides extreme stiffness and light weight
- oversized DUB spindle to work across every bottom bracket standard
- chainring technology is designed specifically for Eagle™ chains and drivetrains
- The X-SYNC™ 2 chainring provides significantly quieter performance, with better mud clearing and extraordinary durability
- Carbon Crank Boot
Version for 49 mm standard chainline.
DUB™
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.
CARBON TUNED™
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.
X-Sync 2
X-SYNC™ 2 Eagle is the next evolution of SRAM X-SYNC™ technology. The aggressive teeth design provides better chain retention for a smoother, more efficient pedal feel. With a focus on long wear-life, the X-SYNC EAGLE™ design reduces friction and the accumulation of mud, grit and grime.
