Favero Assioma PRO RS‑2 Power Pedals (Dual‑Sided, Shimano SPD‑SL)

The Favero Assioma PRO RS‑2 power pedals set a new benchmark for lightweight, reliable and precise power measurement in road cycling. Built for riders who demand pro‑level accuracy and durability, the RS‑2 system delivers dual‑sided power data in a Shimano SPD‑SL–compatible pedal weighing just 124.8 g per side, making it one of the lightest road power meter pedals available.

Widely supported by bike shops in Australia and trusted by cyclists across the World, the Assioma PRO RS‑2 is a go‑to choice for structured training, racing, and professional bike fitting, where repeatable accuracy and ease of use matter most.

Split‑Architecture Design for Durability and Easy Maintenance

The Assioma PRO RS‑2 uses Favero’s proven split approach, where all electronics and the rechargeable battery are housed safely inside the power spindle—completely sealed and independent from the pedal body. This design improves reliability in wet weather, simplifies maintenance, and ensures consistent performance with no power dropouts during long rides or races.

Proven Accuracy with Advanced Cycling Metrics

Powered by Favero’s IAV (Instantaneous Angular Velocity‑based) Power System, the RS‑2 delivers ±1% accuracy, even with oval chainrings. Dual‑sided measurement provides complete left/right balance and advanced data used by coaches, sports scientists, and bike fitters.

Metrics available include:

• Power and Cadence
• Left/Right Balance
• Pedal Centre Offset (PCO)
• Power Phase (PP)
• Pedal Smoothness (PS)
• Torque Effectiveness (TE)
• Rider Position

These insights help riders optimise efficiency, diagnose asymmetries, and track progress with confidence.

Lightweight Ergonomics for Performance Riding

A low stack height of 10.5 mm and +53 mm Q‑factor create a natural pedalling position, supporting comfort and biomechanical efficiency on long road rides. The pedal body is constructed from carbon‑fibre‑reinforced techno‑polymers, balancing stiffness, durability and weight for high‑performance use.

Seamless Connectivity and Long Battery Life

The Assioma PRO RS‑2 connects via ANT+ and Bluetooth, pairing easily with major bike computers, smart trainers and training apps. Built‑in cadence sensing and gyroscopes eliminate additional sensors, while rechargeable lithium‑ion batteries provide up to 160 hours per charge (via firmware update).

An IP67 rating ensures reliable operation in wet conditions, making these pedals suitable for year‑round Australian riding.
