It has been our observation that roadies produce numbers in the 70’s to mid 80’s range, while mountain bikers may see much lower values because they spend more time standing on the pedals. The manual does mention:Īs a general rule, higher numbers are better than lower numbers. The first problem though, was to understand what good looks like. One of the main reasons I bought the computrainer was to be able to measure my technique so that I could improve my pedaling efficiency. ATA (Average Torque Angle): displays the average point in degrees that represent efficient crank arm length usage.*.If your legs could produce power like an electric motor, the graphs would be perfectly flat (or round) and the SpinScan values would be 100, as in 100% efficient.*
The more efficiently you use the muscles in your legs to “pedal in circles”, the higher the SpinScan values will become and the flatter (bargraph) or rounder (polar) the SpinScan Torque Profile will become. SpinScan: The SpinScan number is defined as: Average Torque divided by Maximum Torque multiplied by 100. In essence, the SpinScan numbers represent efficiency of the muscle groups in the legs to produce power evenly through the stroke.For those who know the Computrainer, it is a very good tool to analyze your pedaling.
