The SRAM AXS Power Meter Spider is a Quarq-based power measuring spider that mounts directly to compatible SRAM AXS cranksets — delivering dual-sided power measurement without replacing the whole drivetrain. Accurate watt, cadence, and torque data transmits via ANT+ and Bluetooth to compatible head units and GPS computers.

Highlights

  • Quarq power meter spider for SRAM AXS cranksets
  • Dual-sided power measurement — total power, left/right balance
  • ANT+ and Bluetooth transmission — compatible with all major head units
  • No separate battery pack — integrates cleanly into the drivetrain
  • Available for multiple AXS crankset configurations

Quarq accuracy

Quarq power meters use strain gauges bonded to the spider arms — measuring the deflection caused by pedalling force at the actual point of power transfer. SRAM acquired Quarq in 2011 and the technology underpins the full range of SRAM power meter products. Temperature compensation and calibration are handled automatically.

Fit and compatibility

AXS Power Meter Spider for SRAM AXS cranksets. Confirm crankset model and spider compatibility before ordering — not all AXS cranks use the same spider interface. Requires compatible head unit with ANT+ or Bluetooth power meter support.
