Favero Assioma PRO RL-1 Power Meter Pedal (Single-Sided, Look KEO)

Single-sided power on Look® KEO. 160-hour battery. Upgradable to dual later. The smart way into pedal-based power.

The Favero Assioma PRO RL-1 is the single-sided version of Favero's new Look® KEO–compatible road power meter pedal. Power sensor lives in the left pedal; the right pedal is a regular KEO pedal. Same Italian build, same 160h battery, same accuracy — at a price most riders can actually justify.

Why riders choose Assioma PRO RL-1

Real power data without the dual-sided price tag. If you don't need true L/R balance, paying €290 more for the dual version doesn't change your training. PRO RL-1 gives you the same accuracy and same metrics that 99% of riders actually use day-to-day: power, normalized power, IF, TSS, cadence.

160h USB-C rechargeable battery. Coin-cell competitors die at the worst moment. PRO RL-1 charges magnetically like your head unit — weeks of riding between top-ups.

No calibration ritual. Auto temperature compensation + Favero's IAV algorithm mean the number is right when you clip in. No more "is my power meter lying to me today?"

Future-proof: upgradable to PRO RL-2. Decide later you want true dual-sided? Buy the PRO RL-UP upgrade kit and convert your single into a dual without replacing what you already own. Almost no other pedal power meter offers this.

Look® KEO standard, fully adjustable release tension. Reuse your existing KEO cleats. Tune the release feel for endurance comfort or race-day hold.

Practical ride benefits

• Pace your climbs and intervals with real watts, not guesswork from heart rate.
• Train to a structured plan (TrainerRoad, Zwift Workouts, indoor erg) without buying a smart trainer.
• Move from bike to bike in 5 minutes — gravel, road, indoor.
• Pair with Garmin, Wahoo, Hammerhead, Zwift via ANT+ and Bluetooth simultaneously.

Where competing single-sided meters fall short — and how PRO RL-1 fixes it

• Coin-cell pedals die unexpectedly. PRO RL-1 is rechargeable, 160h runtime.
• Crank-arm single-sideds are stuck on one bike. PRO RL-1 moves between bikes in minutes.
• Most single-sided meters can't be upgraded. PRO RL-1 can become a true dual with the upgrade kit.
• Many pedals need regular zero-offset. PRO RL-1 stays calibrated — clip in and ride.
