Will I have to buy one for each type of shaft? CM, stainless, and Ti will all flex differently. And as asked earlier, how do you account for flex without drive torque?
1) Supposedly, the sensor(s) can measure the shear of the pedal spindle, not just its bending. (???)
2) If you're standing up and stretching (while softpedaling)... since you know the direction of the pedal force, you know the positive torque from one leg and negative torque from the other leg. You add them up for a net torque of zero. (I always wondered how Ergomo dealt with this, by the way. Not very well, I guess lol)
