an swiss replica watches accomplished racer

If I hadnt gone to see bike-fit guru Andy Pruitt, PhD, this pastJanuary, Im not sure how much longer I could have continued cycling. Pruitt, founder of the Boulder Center for Sports Medicine, literally wrote the book on bike fitting. He’s also an swiss replica watches accomplished racer—a two-time world champion in disabled cycling (he’s a below-the-knee amputee on his right side) who achieved elite Category 2 status against able-bodied cyclists. I’ve crossed paths with him at a few cycling-industry events over the years, and hes suggested some minor position tweaks.

But it wasn’t until he got me to his lab in Boulder, Colorado, that we realized what a biomechanical disaster I really am.Since about the age of 30 (I’m 37), I’ve had a dull pain in my left knee that has grown more pronounced each year. Increasingly, it swiss replica watches has forced me to cut my bike rides short. I’ve also had lower-back pain, though I’ve generally been able to ride through that. I attributed all of this to injury buildup—I suffered a partial tear of the MCL in my left knee once, and I’ve also broken both ankles and a wrist and had arthroscopic surgery on a shoulder. But Pruitt discovered that my knee pain was largely due to the fact that my right leg is a full centimeter shorter than my left.

X-rays we took at his lab showed my hips tilting down drastically to the right, with my spine twisting to compensate. (The image at right shows me standing up straight.) Pruitt also found that my toes point further out than normal and that I have a more pronounced varus tilt than average (hang your legs off the edge of a table and note how the replica brand watches outside of your foot drops down lower than the inside; that’s varus tilt). Basically, my feet were too flat on the pedals and pointing too close to straight forward, which forced my knees to roll in and twist laterally. And by settling on a saddle height that felt most comfortable (or, rather, least painful), I was actually sitting too low for my left leg and too high for my right. My left knee was suffering from a lifetime of being over-torqued.“The knee is usually the victim,” Pruitt told me.
