Favero Assioma PRO RS-1 Road Power Meter Pedals

The Favero Assioma PRO RS-1 Road Power Meter Pedals bring Favero’s latest PRO spindle technology to the road! Unlike the DUO and UNO models that rely on external pods, the new RS-1 pedals feature a podless design that reduces weight, protects internal electronics and delivers a cleaner look. Built around the Shimano SPD-SL cleat system, these pedals are not only durable and highly accurate, they’re also the lightest single-sided road power meter pedals on the market at just 246 grams for both pedals.

The RS-1 power meter pedals feature a 53 mm Q-Factor and a 10.5 mm stack height which is very much on par with a standard road pedal. They are also easy to install and can be moved between bikes. This is great for riders who have multiple bikes but only want to purchase one power meter.

Additionally, the PRO RS power meter pedals are +/- 1.0% accurate and provide advanced metrics like Power Phase, Pedal Smoothness, Torque Effectiveness and Platform Center Offset (PCO). They have a rechargeable battery with 60-hour battery life and come with a full 2-year warranty.

Power Measurement

Advice From Our Staff

Favero continues to produce accurate, reliable, lightweight and good-looking power meter pedals. The PRO RS pedals use the same technology as the PRO MX mountain bike pedals which have been one of our top-selling power meters. Because these are single-sided power meter pedals, they are also very affordable. If you are looking for a road power meter pedal for Shimano SPD-SL cleats, the RS-1 checks every box you could want in a power meter pedal.

3 reviews for Favero Assioma PRO RS-1 Road Power Meter Pedals
  1. James Meister

    Installation, initial registration, charging, firmware update, calibration and pairing to my Garmin Edge 130+ were all smooth and easy. Looks and feels just like the Dura-Ace pedals they replaced. Only have 100 miles on the Assiomo Pro RS-1, but have had no dropouts, squeaks or other problems. Even the packaging shows that Favero pays attention to detail and offers a quality product.

  2. Tom (verified owner)

    Easy to install, easy to charge, easy to pair to my Garmin Fenix. App works great too. Somehow it’s easier to click in the first time with these compared to the Shimano PD-R550. Overall very happy with this investment.

    • Power Meter City

      Hi Tom! Thanks for sharing your experience! We’re glad the install, charging, and pairing went smoothly and that you’re happy with your investment. Enjoy every ride with your new setup!

  3. Bill (verified owner)

    Works great. Simple install with wrench (plenty of space for standard wrench even). Highly recommend if you want Shimano cleats (also have a pair of the Favero with Look cleats and they work fantastic for years)

    • Power Meter City

      Glad to hear it’s working great and the install was straightforward! Thanks for recommending it, especially for Shimano cleats. We’re happy you’re enjoying both Favero options!
