Favero Assioma Duo-Shi Power Meter

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.
