ASSIOMA DUO-SHI by Favero Electronics
Professional Cycling Power Meter
Cycling power meter with sensors on both pedals. The best choice to take full advantage of real dual-sided measurement.
compatible with Shimano® pedal bodies*
Designed for the compatibility with
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.
stallation into your own
Installing Assioma DUO-Shi into your own compatible Shimano® pedal
bodies* is simple and quick. Watch our
video for the installation
Assioma DUO-Shi is compatible with the following Shimano® pedal
bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540.
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 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 analyze 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
. 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
