HOW IS TORQUE MEASURED?
TORQUE // Fave x 9.8 x L = Torque
(Fave = Average Force per Revolution )x(9.8 = gravitational constant)x (L=Length of Crank)
To measure TORQUE, Stages’ proprietary strain gages are laid precisely along the crank arm. These gages, which are the same tool used in aerospace, can detect the smallest flex in the stiffest crank. In this case, every pedal stroke, causes a small amount of flex along the crank arm. This downward force happens in every rotation. This force, multiplied by 9.8m/s2 and the length of crank arm are used to determine the force applied to a pedal stroke, or torque.
