Experience peak road performance with the Assioma PRO RS—the lightest dual-sided power meter pedals available at just 123.5 g per side. Designed for Shimano® SPD-SL® cleats, these pedals deliver pro-level accuracy and 60+ hours of battery life, ensuring smooth data transmission with zero dropouts. At the core is Favero’s fully sealed stainless-steel spindle, which houses all essential electronics and the rechargeable battery. This smart split-body architecture separates the power sensor from the pedal body, enhancing durability, water resistance (IP67), and serviceability. With a +53 mm Q-factor and just 10.5 mm stack height, the Assioma PRO RS provides optimal biomechanical efficiency—perfect for competitive road cyclists and serious training sessions. Powered by the IAV Power System, it guarantees ±1% accuracy across all efforts, even with oval chainrings or variable cadence. Cyclists also gain access to advanced cycling dynamics, including L/R Balance, Power Phase, Torque Effectiveness, and Platform Center Offset (PCO). Its modular design allows you to switch between road and MTB pedal bodies while keeping the same high-precision spindle. Whether you're racing, training, or optimizing your ride data, the Assioma PRO RS is the ideal tool to ride harder, smarter, and faster.

FAQs
1. What exactly is the Favero Assioma PRO RS-2 power meter? It’s a dual-sided power meter pedal designed for road cyclists, using Shimano SPD-SL cleats to track power output from both legs separately. Think of it as a high-tech tool that gives you precise data to fine-tune your performance, whether you’re training for a race or just geeking out over your ride stats.
2. Will it work with my Shimano cleats? Absolutely! The PRO RS-2 is built to pair perfectly with Shimano SPD-SL cleats, so you can slap these pedals on your road bike and keep using your favorite shoes without any hassle.
3. How accurate are the power readings? These pedals are seriously precise, boasting ±1% accuracy thanks to Favero’s Instantaneous Angular Velocity (IAV) tech. Whether you’re rocking oval chainrings or sprinting at a wild cadence, you’ll get reliable numbers every time.
4. What’s the difference between the PRO RS-2 and PRO RS-1? The PRO RS-2 measures power from both pedals, giving you detailed left/right balance and advanced metrics like pedal smoothness. The PRO RS-1, on the other hand, is single-sided, only reading from your left pedal, so it’s a bit more basic but still solid for beginners.
5. How long do the batteries last? You’re looking at over 60 hours of ride time per charge, which is enough for weeks of riding for most of us. When it’s time to juice up, the magnetic USB cable makes charging a breeze—just snap it on and you’re done.
6. Can these pedals handle wet and messy conditions? Oh yeah, they’re IP67-rated, meaning they’re sealed tight against rain, mud, and dust. I’ve seen riders on Zwift forums swear by them for sloppy winter rides, and the data stays rock-solid no matter the weather.
7. Is setup a pain? Not at all! You install them like regular pedals—just screw them into your cranks. Pairing with your bike computer or phone is easy with the Favero Assioma app, which handles calibration and updates in a few taps. Even tech-averse riders will find it straightforward.
8. What devices or apps can I use with the PRO RS-2? These pedals play nice with pretty much everything—Garmin, Wahoo, Zwift, Strava, TrainerRoad, you name it. They connect via Bluetooth and ANT+, so syncing with your cycling computer or indoor training setup is seamless.
9. Are they heavy? Nope! At just 123.5 grams per pedal, they’re some of the lightest dual-sided power meters out there. Plus, the +53mm Q-factor feels natural, so you’re not throwing off your ride position or adding unnecessary bulk.
10. Is the PRO RS-2 worth upgrading to? If you’re serious about digging into your performance—think left/right power balance, torque effectiveness, or pedal smoothness—the PRO RS-2 is a no-brainer. It’s a premium tool for cyclists who want pro-level data without the pro-level price tag.
