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.
