A dual-sided, pedal-based power meter for the rider who wants true left/right power data on every bike they own, with enough bike-to-bike portability to move it between a road, gravel or indoor trainer setup in minutes.
Overview
Favero's Assioma pedal power meters solve the one problem every crank- or spider-based power meter has: they're locked to a single bike. Because the power sensor lives in the pedal body itself, the Assioma PRO RS-2 swaps between bikes using nothing more than a pedal wrench, which makes it the most flexible way to get genuine dual-sided power data across more than one bike.
The RS-2 measures power independently in each pedal using Favero's IAV (Instantaneous Angular Velocity) method and a built-in gyroscope, reporting true left/right power split rather than doubling one side's reading. Each pedal runs on a rechargeable lithium-ion battery rated for at least 60 hours per charge, broadcasts over both ANT+ and Bluetooth, and uses an SPD-SL-compatible cleat interface (Shimano SM-SH10/11/12-pattern cleats are included). The pedal body itself uses carbon-fibre-reinforced tech-polymer construction with a modular design, so a damaged pedal body can be replaced without discarding the electronics inside.
It suits a rider who already owns a quality set of road pedals and wants to add accurate power data without committing to a crank- or hub-based system tied to one bike - including triathletes who swap a power meter between a road and TT bike, and indoor-training riders who want the same power numbers on the turbo as outdoors.
Why You'll Like It
True dual-sided power. Each pedal has its own independent power sensor, so the RS-2 reports genuine left/right power and pedalling balance rather than an estimate doubled from one side.
Moves between bikes in minutes. Because the sensor is in the pedal, switching this power meter from a road bike to a gravel bike or a trainer bike only takes a pedal wrench, not a crank or wheel swap.
Dual connectivity. Simultaneous ANT+ and Bluetooth broadcasting means it works with ANT+ head units, Bluetooth-only smart trainers, and phone-based ride apps without a bridge accessory.
Rich ride metrics via the app. Paired with the Favero Assioma app or an ANT+ head unit, it reports Power Phase, Pedal Smoothness, Torque Effectiveness and Rider Position data alongside raw power and cadence.
Rated accuracy with thermal compensation. Favero rates the system to within ±1% power measurement accuracy, with built-in thermal compensation to keep readings consistent as temperatures change through a ride.
Weatherproof sealing. An IP67 rating means the electronics are sealed against dust and heavy rain, which matters for a part that sits exposed at the lowest point of the bike.
Who Is It For?
This is for a rider who wants serious, structured-training-grade power data - for FTP testing, interval pacing, or race-day power targets - but doesn't want to be locked into a single bike the way a crank- or spider-based meter would lock them in.
It particularly suits triathletes and multi-bike owners in India who train on a road or TT bike outdoors and also ride a smart trainer indoors through the monsoon months, since the same pedals and the same power numbers travel with the rider rather than staying fixed to one crankset.
Good to Know
The Assioma PRO RS-2 ships with SPD-SL-pattern cleats, so a rider moving from a different pedal system (such as Look Keo or Speedplay) should budget time to re-fit their shoe cleats before the first ride.
Pairing with the free Favero Assioma app on a smartphone unlocks the full metric set - Power Phase, Pedal Smoothness, Torque Effectiveness and Rider Position - on top of the power and cadence numbers any ANT+ or Bluetooth head unit will already show.
Because the system is oval-chainring compatible, riders running a non-round chainring don't need to make any special allowance when installing or calibrating the pedals.
A quick zero-offset calibration before each ride, done from the head unit or app, keeps the ±1% accuracy rating consistent ride to ride.
