SRAM XX1 Eagle Power Meter Boost Chainset

Every innovation in Quarq's DZero platform represented the 10+ years of Quarq's advances in power meter technology. This same platform is now combined with XX1 Eagle DUB Carbon Tuned crankset - lightest, stiffest and strongest to date, and X-Sync 2 chainring - providing significantly quieter performance, with better mud clearing and extraordinary durability. Ready to power every ride.

Technology

Eagle

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 520%, which is equal to 2x11 drivetrains.

X-Sync 2

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.

AXS

AXS is SRAM’s new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.

DUB

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.
