Favero Assioma PRO RS‑1 Power Pedals (Single‑Sided, Shimano SPD‑SL)
The Favero Assioma PRO RS‑1 power pedals are engineered for cyclists who want elite‑level accuracy, minimal weight, and simple setup in a Shimano SPD‑SL pedal platform. Built and tested in Italy, the RS‑1 delivers Favero’s proven power‑measurement technology in a single‑sided configuration, making it an ideal entry into power‑based training without changing cranks or wheels.
Available through leading bike shops in Brisbane and trusted by riders across Queensland and Australia, the Assioma PRO RS‑1 is frequently recommended for structured training, coaching programs, and professional bike fitting, where reliable data and repeatability matter.
Class‑Leading Weight with Pro‑Grade Ergonomics
At just 123.5 grams for the left pedal, the Assioma PRO RS‑1 is one of the lightest road power meter pedals available. The Shimano SPD‑SL–compatible interface ensures wide cleat availability and a familiar feel for road cyclists.
A low 10.5 mm stack height and +53 mm Q‑factor promote a natural pedalling position, supporting comfort and biomechanical efficiency over long training sessions and endurance rides.
Split‑Architecture Design for Reliability
Favero’s signature split approach places all electronics and the rechargeable battery safely inside the power spindle, fully sealed and independent from the pedal body. This design improves durability, simplifies maintenance, and ensures consistent data with no power dropouts, even in wet conditions.
An IP67 water‑resistance rating makes the RS‑1 suitable for year‑round riding in Australian conditions.
Accurate Power Measurement with Advanced Insights
Using the IAV (Instantaneous Angular Velocity‑based) Power System, the Assioma PRO RS‑1 delivers ±1% accuracy, even when used with oval chainrings. Power is measured on the left side and calculated as total power, offering reliable data for training progression.
In addition to power and cadence, the system provides advanced cycling dynamics often used by coaches and fitters:
- Power
- Cadence
- Power Phase (PP)
- Pedal Centre Offset (PCO)
- Pedal Smoothness (PS)
- Torque Effectiveness (TE)
- Rider Position
These metrics help riders fine‑tune technique and assess changes from fit adjustments or equipment swaps.
Seamless Connectivity and Long Battery Life
The Assioma PRO RS‑1 pairs easily via ANT+ and Bluetooth with popular bike computers, smart trainers, and training apps. Built‑in cadence sensing and a gyroscope eliminate external sensors.
A rechargeable lithium‑ion battery provides up to 160 hours per charge (via firmware update in the FAVERO app), with magnetic connectors for quick charging.
Modular and Future‑Proof
The RS‑1 shares Favero’s modular design, allowing riders to upgrade to dual‑sided power later or switch between road and MTB pedal bodies while keeping the same power‑sensor platform—an advantage for long‑term ownership.
