So here is some interesting technology. Not totally sure how it works but here is my struggling attempt to explain the mass of cords. Bare with me.... So there are a number of stragegically placed sensors that I believe send thousands of waves to the computer measuering their every movement. Thus giving you your exact range of motion. (Sort of a stick man on the screen of the computer) Plus it shows exactly how your knee tracks up and down. (Very important for injury prevention) Very cool. So a few changes in the saddle / foot position and I will be mechanically sound and maybe even a bit more wattage. Who knows.
