Favero Assioma UNO Power Meter PedalsThese Power Meter Pedals from Favero have been designed to help you perform during training sessions. Featuring a single power sensor on the left pedal, they utilise IAV Cycling Dynamics technology to guarantee reliable pedalling data, not just an estimation. These pedals are Bluetooth and ANT+ compatible and benefit from up to 50 hours of battery life, making them the ideal choice for any cyclist looking to up their game. IAV Power SystemMany 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 CompensationRain, 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 MadeThe 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: On the left pedalCadence Sensor: Included, inbuiltGyroscope: Included, inbuiltPower Calculation System: IAV (Instantaneous Angular Velocity-based)IAV Cycling Dynamics: YesOval-chainring Compatible: YesBattery Type: Rechargeable Lithium batteryBattery Life: At least 50 hoursRadio Communication: Bluetooth v4.0, ANT+ PWR profile (CT + PO)Accuracy Power Measurement: 1%Temperature Compensation: -10°C / +60°CWater Resistance Degree: IP67Q-Factor: 54mmHardware upgrade to Assioma DUO always availableCompatible Cleats: Original LOOK Kéo and Favero cleats (red and black)Bike Type: Racing, RoadMade in ItalyWarranty: 2 yearsTotal Weight Per Pedal: 151.5g (battery included)In the Box:Left pedal with power sensorRight pedal without power sensorBattery charger including plugs (EU, US, UK, AU)1 two-metre-long micro-USB/USB cable with magnetic connector2 red cleats float 6° (LOOK Kéo compatible)Hex key and 4 washers for the installation• User manualTechnologies:Easy to Install: Install and transfer your Assioma from one bike to another just like normal pedals, easily and without extra tools.

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.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.
