Power Measurement, BYO Pedals

The Favero Assioma DUO-Shi power meter has been designed for Shimano® road users, as it offers the opportunity to keep on riding with your current Shimano® pedal bodies without giving up on the trustworthy precision of Assioma.

This dual-sided power meter measures power individually on both legs; this makes possible to observe with accuracy not only Total Power, but also L/R Balance.

Data For Days

Assioma bike power meter pedals provide advanced metrics called IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, permit you to analyze your pedaling technique in detail and learn about how your position on the bike influences your performance.

Unlike others, when calculating power Assioma takes into account inevitably irregular pedaling (e.g. uphill, sprints) or the use of oval chainrings. This is because Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions.

Assioma features both Bluetooth and ANT+ connectivity for a seamless compatibility with bike computers and smartphones (both Android and iOS).

Waterproof, Tough, Light, & Rechargeable

The power sensors are protected by a bi-component resin block, extremely resistant to shocks and completely waterproof.

Assioma power meter pedals use rechargeable batteries with a single charge ensuring at least 50 hours of use.
