Upgrade your SPD-SL pedals with the Favero Assioma Duo-Shi Power Meter, and reap the benefits of training with power. Accuracy is high, to just ± 1%, and readings consistent, and these power meters install easily and quickly into your existing pedal bodies as well as transferring between pedals with no need for special tools. Each Assioma communicates with smartphones and cycling computers via Bluetooth and ANT+ so you can monitor real-time data including Total Power, L/R Balance, Torque Effectiveness (TE) and Pedal Smoothness (PS) while you ride.
ATC (Automatic Temperature Compensation) ensures data isn't affected by changes in temperature, and the sensors are waterproof, shock-resistant and incredibly light. Integrated batteries provide over 50 hours of use before a recharge is required.
Assioma DUO-Shi is compatible with the following Shimano pedal bodies: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540.
IAV cycling dynamics - IAV Power Phase and IAV Rider Position
IAV Power and gyroscope - Assioma is able to detect the actual instantaneous angular velocity during the whole pedal stroke, thus providing ±1% accuracy in any conditions, not only in the lab
Measurements include Total Power, L/R Balance, Torque Effectiveness (TE) and Pedal Smoothness (PS)
Power sensors are protected by a bi-component resin block, which is extremely resistant to shocks and completely waterproof
Integrated rechargeable batteries
Favero Electronics produces each power meter in-house and tests each of them thoroughly to fully satisfy the standard required by current regulations
