Favero Assioma PRO RS-2 Road Power Meter Pedals
The Favero Assioma PRO RS-2 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-2 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 dual-sided road power meter pedals on the market at just 123.5 grams per pedal.
The RS-2 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 Favero 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.

I could not be more impressed with the RS-2 pedals. Similar to others, I’ve been wanting power pedals from Favero for a long time, but the Q-factor and non-Shimano cleat support was a dealbreaker for me. As soon as the RS-2 pedals where released and available from Power Meter City, I purchased them. I’ve put about 250+ miles on them and they are perfect. The battery life is great, the available metrics are staggering; they are sturdy, strong, and have a clean look. Highly recommend the RS-2’s to anyone looking to upgrade to a power meter pedal.

I bought these to upgrade from the gold standard original Assiomas. Kudos to PowerMeterCity for having them in stock ready for sale as soon as they were released. I have dual record tested them against the Neo2T and the dual sided 4iiii DA PM and they have all been within one watt of each other. Kudos to Favero for maintaining their super accuracy. And the new PCO feature has helped me dial in my cleat position as well. Easily the best power meter pedals on the market!
Power Meter City –
Thanks for the detailed feedback and kudos, Dan! We’re thrilled to hear the new Assiomas are living up to their reputation for accuracy and that the PCO feature is helping you fine-tune your setup. We’re proud to keep them in stock and appreciate your support!
Adrian (verified owner) –
Been riding these new RS-2 for about 2 weeks now. I decided to go back to regular q factor after riding duo-shi for few years. Strange feeling for the first few rides but now I’m very happy with these RS-2. They look very cool and Assioma products are high quality
In terms of data..super accurate just like the duo-shi. Also I like the new feature of Platform centre offeset PCO
Power Meter City –
Thanks for sharing your experience with the RS-2 pedals! Glad to hear you’re happy with the switch back to a regular Q factor and that you’re enjoying the accuracy and new PCO feature. Assioma definitely makes high-quality gear. Enjoy the rides!
Craig (verified owner) –
I’ve wanted to go with Favero ever since they came out with the Shi version of their pedals, but couldn’t get around the massive increase in the Q-factor. I was stoked to see these new RS-2 pedals specifically designed for the SPD-SL cleats. I’ve only ridden them a few times and could not be happier with them. DC Rainmaker and GP Lama give them glowing reviews and those guys are my go-to when considering new bike gear. Installation and setup is super easy and their redesigned app is a plus. The charging cables are nice and long making it easy to charge without having to remove the pedals. The 60 hour battery life means I should only need to recharge around once a month.
Power Meter City –
Thanks for sharing your experience with the Favero RS-2 pedals, Craig! We’re glad to hear they’re hitting the mark for you, especially with the SPD-SL compatibility and easy setup. Long battery life and convenient charging are definitely game changers. Enjoy every ride!
