FAVERO ASSIOMA – PRO RS-1: The Lightest Road Power Meter Pedal
The FAVERO ASSIOMA – PRO RS-1 is the lightest road power meter pedal available, with a weight of just 123.5g per pedal. Designed for pro-level performance, it is compatible with Shimano® SPD-SL® cleats. It also delivers over 60 hours of use per charge, so there are no power dropouts. All of the important electronic parts and the battery are safely housed within the power spindle. This part is completely sealed and independent from the pedal body. This “split approach” makes the pedal incredibly durable and easy to maintain. Therefore, with its sleek design, a Q-factor of just +53mm, and a stack height of 10.5mm, this power pedal is perfect for improving performance and achieving results during your road training.
Pro-Level Accuracy and Advanced Metrics
The FAVERO ASSIOMA – PRO RS-1 power meter offers ±1% accuracy thanks to the IAV Power System. This provides the most complete power data reading available with a wealth of advanced metrics. For instance, it gives you reliable data even with oval chainrings. A modular design lets you switch between road and MTB bodies while keeping the same power sensor. This makes the pedal a versatile choice for any serious cyclist.
Train with Precision and Ride with Confidence
The FAVERO ASSIOMA – PRO RS-1 is the best power meter pedal for training with precision and riding with confidence. The pedal body is made from high-quality carbon-fibre tech-polymers. This ensures a durable and lightweight construction. The low stack height and standard Q-factor create an ergonomic and efficient connection to your bike. Furthermore, the long-lasting, rechargeable battery gives you peace of mind on every ride. These pedals are also proudly Made in Italy, reflecting superior craftsmanship and attention to detail.
