Product Description
The Quarq DZero XX1 Eagle Power Meter Crankset combines SRAM’s premium carbon XX1 Eagle crank arms with Quarq’s proven spider-based power measurement technology. Designed for performance-focused mountain bike riders, it delivers accurate training data while maintaining the stiffness, low weight, and chain retention expected from an XX1 Eagle drivetrain.

This configuration includes 170mm crank arms, a 32T X-SYNC 2 chainring, SRAM DUB spindle interface, and Boost compatibility. The DZero power meter measures power from both legs with claimed accuracy within ±1.5% and transmits ride data through both ANT+ and Bluetooth Low Energy.

Quarq’s MagicZero technology continuously checks and recalibrates the power meter while riding, reducing the need for manual zero-offset procedures. Built-in 10K Temperature Compensation helps maintain consistent readings as conditions change.
