Favero's lightest road power pedal, built for riders on Shimano SPD-SL cleats. The Assioma PRO RS seals its electronics and battery inside the spindle for ±1% power with nothing hanging off the crank.

Highlights

  • Single-sided: power sensor in the left pedal
  • ±1% accuracy with IAV power system, oval-chainring compatible
  • 124.8g per power pedal; 10.5mm stack; +53mm Q-factor
  • Up to 160 hours per charge (with current firmware), magnetic charging
  • ANT+ and Bluetooth, IP67
  • 100% Shimano SPD-SL cleat compatible; cleats included

The split approach

The power spindle houses the electronics and battery, fully sealed and independent of the pedal body. That makes the pedal durable and easy to maintain, and a modular design lets you swap road and MTB bodies while keeping the same sensor.

Advanced metrics

Favero's IAV system uses a built-in gyroscope for ±1% accuracy, even with oval chainrings. Via ANT+ or the Favero Assioma app you get power, cadence, PCO, power phase, pedal smoothness and torque effectiveness, plus rider position over ANT+.

Road-race dimensions

A carbon-fibre techno-polymer body keeps weight down, while a 10.5mm stack height and +53mm Q-factor give a natural, efficient position.

Compatibility & fit

Compatible with Shimano SPD-SL cleats SM-SH10, SM-SH11 and SM-SH12, and Favero's SPD-SL 6° cleats (supplied). Road bikes. Installs like a regular pedal and auto-calibrates; works on any crank including oval chainrings. Connects over ANT+ and Bluetooth to bike computers, watches and apps. Rechargeable lithium-ion battery (no coin cell). The 160-hour battery figure requires a firmware update via the Favero app. Upgrade to dual-sided at any time with the Assioma PRO RS-UP right pedal. Power-meter pedal fitting and pairing with your head unit is available from our workshop as a separate service, not included in the price.

Favero covers Assioma power meter pedals with a 2-year warranty against manufacturing defects. For warranty support, return the product to Tune Cycles and we'll manage the claim with Favero's Australian distributor.
