Favero Assioma DUO Power Meter PedalsThese Power Meter Pedals from Favero have been designed for high-performance training sessions. Featuring a power sensor on both pedals, they benefit from leading technology to provide you with enhanced readings, not estimations. These pedals provide an in-depth overview of your pedal power, they are Bluetooth and ANT+ ready and include up to 50 hours of battery life. The ideal addition for riders who want to outperform every time. IAV Power System:Many power meters calculate the 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 pedalling, even with oval chainrings.Automatic Temperature Compensation:Rain, snow, mud, or sweltering heat: Automatic Temperature Compensation (ATC) ensures exact, consistent watt measurements in any weather condition at temperatures between -10°C and 60°C.Waterproof, Resistant and the Lightest Ever Made:The lightest and most compact pedal-based power meter made by Favero: with no protruding elements, it does not interfere with the pedalling. Not even when cornering. Protected by a bi-component resin block, the power meter sensor is extremely resistant to shocks and fully waterproof.Features: Power Sensor: Power sensor on both pedals Power Measurement: Dual-sided power measurement Cadence Sensor: Included, inbuilt Gyroscope: Included, inbuilt Power Calculation System: IAV (Instantaneous Angular Velocity-based) IAV Cycling Dynamics: Yes Oval-chainring Compatible: Yes Battery Type: Rechargeable Lithium battery Battery Life: At least 50 hours Radio Communication: Bluetooth v4.0, ANT+ PWR profile (CT + PO) Accuracy Power Measurement: 1% Temperature Compensation: -10°C / +60°C Water Resistance Degree: IP67 Q-Factor: 54mm Compatible Cleats: Original LOOK Kéo and Favero cleats (red and black) Bike Type: Racing, Road Made in Italy Warranty: 2 years In The Box: • Left pedal with power sensor • Right pedal with power sensor • Battery charger including plugs (EU, US, UK, AU) • 2 two-meter long micro-USB/USB cables with 2 magnetic connectors • 2 red cleats float 6° (LOOK Kéo compatible) • Hex key and 4 washers for the installation • User manual Total Weight Per Pedal: 151.5g (battery included)Technologies: Easy to Install: Install and transfer your Assioma from one bike to another just like normal pedals, easily and without extra tools.

These metrics, combined with the classic power data, allow analysing in details the pedalling technique and how the cyclist's position on the bike influences performances. IAV Power and Gyroscope: Unlike others, the measurements of Assioma are not affected by errors related to very irregular pedalling (e.g. 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 and ANT+ SMART: Assioma communicates via Bluetooth and ANT+ with bike computers and smartphones, both Android and iOS. Real Dual-Sided Power Data: Assioma DUO provides dual-sided data through real measurements: taken individually on both the left and the right leg; this makes 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 Consistency: Assioma provides accurate watt measurements with 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 light: Assioma is the lightest pedal-based power meter ever made. Thanks to its compact design, it never interferes with the pedalling. Not even when cornering. The power sensors are protected in a bi-component resin block, extremely resistant to shocks, and completely waterproof. Rechargeable and Green: Assioma 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.Buy Favero Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
