The Quarq DZero power meter spider delivers accurate, reliable watt data for riders who want to train and race with precision. Designed for SRAM DUB cranks with a 130 BCD chainring interface, this spider-only unit lets you build your ideal drivetrain without replacing crank arms you already own.

  • ±1.5% accuracy across all four quadrants of the pedal stroke
  • DUB spindle compatible — works with SRAM DUB bottom brackets
  • 130 BCD interface suits compact, standard and mid-compact chainring configurations
  • Dual ANT+ and Bluetooth Smart for maximum head unit and app compatibility
  • Auto-zero function keeps calibration honest without stopping mid-ride

Quarq's DZero platform uses strain gauges bonded directly to the spider to measure power accurately across temperature extremes and varying cadences. The CR2032 battery is user-replaceable and delivers long service life. OmniCal technology automatically calibrates the meter for any chainring combination without additional setup.

Compatible with SRAM DUB cranksets (crank arms sold separately). Requires a 130 BCD chainring. Suits 10 and 11-speed drivetrains. Bottom bracket not included.
