Favero Assioma DUO-Shi

Made for Shimano® road compatibility

The Assioma DUO-Shi racing bike potentiometer was designed for cyclists fond of the Shimano® road standard, as it offers the possibility of continuing to race with their own Shimano® SPD-SL® pedal bodies* without having to give up reliability and to the 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 in your own Shimano® pedal bodies

Installing the Assioma DUO-Shi power sensor in your compatible Shimano® SPD-SL® pedal bodies* is quick and easy.

**Q-factor increased?

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

Despite an initial hesitation regarding the increase in the Q-factor, we decided to proceed with the project anyway, taking into consideration that the size of our body (weight, width of the pelvis, etc.) is a subjective factor that can contribute to determine which Q-factor is most suitable for each of us.

Effective positive feedback from our beta testers has definitively validated the product.

Easy to install

Assioma DUO-Shi power sensors can be installed and moved from one bike to another like a common pedal: in a few minutes, without special tools and without the assistance of a mechanic.

IAV Cycling Dynamics

Our power meters offer advanced metrics such as IAV Cycling Dynamics (IAV Power Phase and IAV Rider Position) which, together with classic power data, allow you to analyze in detail the pedaling technique and how the cyclist's position on the bike influences the performance.

IAV Power system and gyroscope

Unlike others, Assioma's measurements take into account our irregular pedaling (e.g. sprints, climbs) or the use of oval chainrings when calculating power, thus guaranteeing an accuracy of ±1% in any situation. This is because Assioma is capable of detecting the actual instantaneous angular speed of pedaling.

Bluetooth and ANT+

Assioma DUO-Shi is equipped with Bluetooth and ANT+ technology for secure data transmission to both cycle computers and Android and iOS smartphones.

Real right/left balance data

The data provided by the Assioma DUO-Shi SPD-SL® dual power meter is based on measurements taken separately on the left and right sides; this allows you to accurately observe not only the total power, but also the left/right balance.

Stability of measurement

Thanks also to ATC (Automatic Temperature Compensation), our potentiometer ensures not only accuracy but also repeatability and consistency of measurements in real conditions of use on the road and at any temperature between -10°C and 60°C.

Waterproof, durable and lightweight

Protected by a two-component resin block, the sensor of our potentiometer is extremely shock-resistant and completely waterproof.

Rechargeable and eco

Favero Assioma DUO-Shi uses integrated rechargeable batteries: a single charge guarantees at least 50 hours of use.

Tested and guaranteed

Favero Electronics produces each potentiometer in its headquarters in Italy and tests its good functioning individually through careful laboratory tests, fully satisfying the standards required by current regulations.
