Many power meters calculate power using the average angular velocity (AVG) per rotation instead of the instantaneous angular velocity (REAL) value: this may introduce an additional error, up to 4.5% compared to the declared accuracy. 

Assioma, thanks to its exclusive IAV Power system and an integrated gyroscope, measures the actual instantaneous angular velocity to guarantee the same ±1% degree of accuracy with any style of pedaling, even with oval chainrings

Easy to install


Install and transfer your Assioma power meter from one bike to another just like normal pedals, easily and without extra tools. Just screw them on your bike crank arms and you are ready to pedal!


IAV Cycling DynamicsAssioma supports the advanced metrics IAV Cycling Dynamics: IAV Power Phase and IAV Rider Position. These metrics, combined with the classic power data, allow analyzing in details the pedaling technique and how the cyclist’s position on the bike influences performances.IAV Power and gyroscopeUnlike others, the measurements of Assioma are not affected by errors related to very irregular pedaling (eg. sprint uphill) or the use of oval chainrings. This is because Assioma is able to detect the actual instantaneous angular velocity of the pedal stroke, thus giving you the degree of accuracy of ±1% in any situation. Not only in the laboratory.Bluetooth SMART and ANT+ Assioma communicates via Bluetooth and ANT+ with bike computers and smartphones, both Android and iOS.


Real dual-sided power dataAssioma DUO provides dual-sided data through real measurements: taken individually on both the left and the right leg; this make it possible to observe with accuracy not only the Total Power, but also the L/R Balance, the Torque Effectiveness (TE), the Pedal Smoothness (PS), etc. Accuracy and consistencyAssioma provides accurate watt measurements with a great consistency and stability in the actual on-road use conditions and at any temperature between -10°C and 60°C. Thanks to the ATC (Automatic Temperature Compensation) too.Waterproof, resistant and lightAssioma is the lightest pedal-based power meter.


Thanks to its compact design, it never interferes with the pedaling: not even when cornering. The power sensors are protected in a bi-component resin block, extremely resistant to shocks and completely waterproof.Rechargeable and greenAssioma is the only pedal-based power meter with integrated rechargeable batteries; a single charge ensures 50 hours of use at least.


Tested and guaranteed Favero Electronics produces in-house each Assioma and thoroughly test it individually: fully satisfying the standards required by current regulations.
