Knowing your power output is the quickest way to efficient and effective advances in your fitness and speed. Sigma has optimized their power formula to attain power output numbers that are based on the power required to move the bike rather then the power asserted on the pedals. Sigma’s formula takes into consideration bike type and position, bike and rider weight, rider height, shoulder width, speed, incline and cadence.
The Sigma Rox 9.1 features over 64 total functions in 12 different categories and uses a digitally encoded 3-channel wireless system. To keep all the data manageable and accessible, the Sigma ROX 9.1 allows you to customize the screen with up to 10 different functions on screen at one time.
