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 trustability and precision of Assioma.


Installation into your own Shimano pedal bodies - Installing Assioma DUO-Shi into your own compatible Shimano pedal bodies* is simple and quick. Watch their video below for the installation.

*Compatible Shimano pedal bodies - Assioma DUO-Shi is compatible with the following Shimano pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and 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.
Despite an initial concern related to the increase of the q-factor, they 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 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 - Assioma provides advanced metrics called IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data permit you to analyse in detail your pedaling 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 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. 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 and resistant - 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 every power meter in-house and tests each of them thoroughly to fully satisfy the standard required by current regulations.

Assioma - love them

Easy to fit your Shimano compatible pedals, if in reasonable condition. Easy to fit to your cranks. Easy to pair with the Assioma app. Easy to do a zero calibration with the app if you swap your pedals to another bike. I have had another power meter pedal system for 5 years. There was no surprises with the power data from the Assioma DUO SHI. I love using the Shimano pedals and cleats again. Oh, did I say it was all so easy? cheers GC

Great quality

Unless you have some serious joint issues don't think twice about the added q factor with these. It took less than 10min to fit these and that included having to find my phone to register them. Took them for a spin today and was glitch free. Great to have the extra feedback on my headunit and to analyze after.
