“The hips and ankles are the culprits.” Then he changed cycling for me. He put shims inside my shoe and under my cleats, to compensate for my varus tilt, and turned the cleats so that my toes pointed out as much as possible. This would keep my feet in replica Gucci watch their natural position throughout the pedal stroke, thus reducing knee strain. Pruitt then moved my left cleat all the way back, which meant that my foot would be farther forward on the pedal, effectively shortening my leg, since it would now have to extend farther at the bottom of the pedal stroke.
He also added three millimeters’ worth of risers under the cleat on my right shoe, effectively lengthening that leg. Combined with the cleat shift on my left shoe, this would roughly equal my legs out. Finally, Pruitt shortened my stem, giving me a more replica watch gift upright (less racer-like) position, which cyclists eventually have to move into in middle age. (Sigh.) All of this took about 10 minutes. (Download bradley-email012108-1.doc) A big part of getting a medical bike fit is video analysis.
Pruitt and BCSM biomechanics technician Sean Madsen set my bike up on a stationary trainer surrounded by an array of video cameras. Madsen attached infrared markers to specific points on my body (hips, knees, ankles, heels, etc.), which the motion-analysis software would use to track my movement in three dimensions. Videos shot before and replica Longines watch after my position changes showed immediate improvement. (Download john_bradley.pdf) I looked more comfortable on the bike, and the motion analysis showed my knees tracking in a much straighter line.
