If you want to train smarter without changing your whole bike setup, the Assioma PRO RS-1 makes it easy. Designed around a sleek spindle-based power meter, all of the electronics and battery sit safely inside a sealed axle — keeping things durable, low-maintenance and incredibly tidy compared to older external pod designs.
This single-sided version measures power from the left pedal to estimate total output, making it a strong choice for riders stepping into power-based training or anyone wanting reliable data without the higher cost of dual-sided systems. Expect consistent ±1% accuracy, even with oval chainrings, so your training numbers stay dependable whether you’re racing, doing structured intervals or just tracking progress week to week.
Favero has kept the feel familiar by building the PRO RS around a Shimano SPD-SL compatible road pedal platform. The wide contact area and low stack height help maintain efficient pedalling dynamics, while the lightweight carbon-fibre reinforced pedal body keeps overall weight impressively low — making it one of the lightest power meter pedals available.
Charging is simple thanks to the integrated rechargeable lithium-ion battery, offering over 60 hours of ride time per charge. Built-in cadence sensing plus ANT+ and Bluetooth connectivity means it pairs easily with head units, training apps and indoor setups, giving you all the metrics you need without extra sensors cluttering your bike.
In short: clean install, accurate data, no drama. Just fit them, clip in and ride.
