Designed for the compatibility with Shimano® road


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 trustability and precision of Assioma.

*Assioma DUO-Shi is compatible with the following Shimano® SPD-SL® pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540.

Installation into your own Shimano® pedal bodies


Installing the Assioma DUO-Shi power meter into your own compatible Shimano® SPD-SL® pedals* is simple and quick. Watch our video for the installation.

Increased Q-factor?


The Q-factor of Assioma Look® version is of +54mm, whereas that of Assioma DUO-Shi measures +64mm with the PD-R7000/R550/R540 pedal bodies and +65mm with the PD-R8000/6800.

Despite an initial concern related to the increase of the q-factor, we decided to proceed with the project considering that body size (height, pelvis width, etc.) is a subjective factor contributing to determining which is the best q-factor for each one of us.

A final, positive feedback from our beta testers has eventually validated the product.

Easy to install


Install and move your Assioma DUO-Shi pedals from one bike to another just like your normal pedals. You can do it easily and without extra tools or the need for a mechanic.

IAV Cycling Dynamics


Our 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.

IAV Power and gyroscope


Unlike others, when calculating power Assioma takes into account our 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.

Bluetooth and ANT+


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

Real dual-sided power data


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

Accuracy and consistency


Assioma guarantees accurate and consistent data in all conditions on the road, and at any temperature ranging from -10°C and 60°C, thanks also to the ATC (Automatic Temperature Compensation).

Waterproof, resistant and light


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

Rechargeable and green


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