The SRAM XX1 Eagle Power Meter unites Quarq's DZero power meter platform with CARBON TUNED crank arms for robust, intuitive power measurement in the lightest ever chassis. The DZero platform embodies 10 years of Quarq's technology advances and adds new features such as dual Bluetooth low energy and ANT+ wireless data transfer, and the Qalvin BLE app. The companion X-SYNC 2 chainrings are designed specifically for Eagle chains and drivetrains.
- Two power meter variations - Conventional and BOOST™ 148 (52mm chainline).
- Requires an X-SYNC 2 or X-SYNC 104 BCD chainring.
- Existing XX1 power meter owners can upgrade using an Eagle Power Meter Spider (Conventional, not BOOST™).
- Free firmware upgrades with the Qalvin app.
SRAM 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™2 Eagle™ design reduces friction and the accumulation of mud, grit and grime.
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.
