The micro sport can not be that accurate. It fits on your shoe?
So much for one legged drills.
From the website...
How It Works:
Force sensing insole inside the shoe. How hard the cyclist pushes on the pedal is measured.
All cyclists apply pedal force and cause torque in the same pattern*
So: torque can be calculated from the measured force!
Angular velocity is calculated from the period of the force curve.
One sensor tells all!
