Favero Assioma Duo-Shi Bike Power Meter 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. This power meter pedals provide 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 your pedaling technique in detail and learn about how your position on the bike influences your performance. Unlike others, when calculating power Assioma takes into account our inevitably irregular pedaling or the use of oval chainrings. This is because Assioma can detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing 1 percent accuracy in any conditions. Assioma features both Bluetooth and ANT+ connectivity for a seamless compatibility with bike computers and smartphones (both Android and iOS). The Favero Assioma DUO power meter pedals measure power individually on both legs. This makes possible to observe with accuracy not only Total Power, but also L/R Balance. Assioma ensures accurate and consistent data in all conditions on the road and at any temperature ranging from -10 Degree Celsius and 60 Degree Celsius, thanks also to the ATC (Automatic Temperature Compensation). The power sensors are protected by a bi-component resin block, extremely resistant to shocks and completely waterproof. The Assioma power meter pedals use rechargeable batteries with a single charge ensuring at least 50 hours of use. Favero Electronics produces every bike power meter in-house and tests each of them thoroughly to fully satisfy the standard required by current regulations. Comes in black color.
