Designed for the compatibility with Shimano® road, Assioma DUO-Shi 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 precision of Assioma.

Easy to install

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

Installation into your own Shimano® pedal bodies

Installing Assioma DUO-Shi into your own compatible Shimano® pedal bodies* is simple and quick.

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

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.

IAV Cycling Dynamics

Assioma provides advanced metrics called IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, permit to analyse in details your pedalling technique and how your position on the bike influences performance.

IAV Power and gyroscope

Unlike others, the measurement of Assioma is not affected by errors related to very irregular pedalling (e.g. uphill sprints) or the use of oval chainrings. This is because Assioma is able to detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions. Not only in the lab.

Bluetooth and ANT+

Assioma communicates with bike computers and smartphones (both Android and iOS) via Bluetooth and ANT+.

Real dual-sided power data

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, Torque Effectiveness (TE), Pedal Smoothness (PS), etc.

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

Assioma is the lightest pedal-based power meter in the market. Thanks to its compact design, it never interferes with the pedalling: not even when cornering. The power sensors are protected by a bi-component resin block, extremely resistant to shocks and completely waterproof.

Rechargeable and green

Assioma is the only pedal-based power meter for road with integrated rechargeable batteries; a single charge ensures at least 50 hours of use.

Tested and guaranteed

Favero Electronics produces each power meter in-house and tests each of them thoroughly to fully satisfy the standard required by current regulations.
