I’ve read that triathlete make sure to turn of auto calibration and calibrate their power meters without their shoes attached.
I wonder why. For example, if I calibrate with shoes attached with cranks in the vertical position, wouldn’t that just add an offset so that the power meter thinks there is an extra force pushing the pedals away/towards the axle. This force results in zero torque with regards to the axis of rotation, thus zero power reading difference?
Additionally, pedal bodies for pedal-based power meters have different weights (Garmin Rally). Pedals themselves have different weights for crank-based power meters. Thus, why would extra weight from say, a shoe, make any difference?
For me, this is important because I am using flat-pedal adaptors on my Favero Assiomas. The way I have it setup, it is quite difficult to remove every time (it’s a long story)
Has anyone tested this with their power meters?
I was thinking of doing some back to back testing to see what the difference.
