I opted out of racing this weekend so I could do some work on my bike position. I have been thinking about this change for a while but after the poor sensations I had a 5 mile pass I decided to give it a try. It all started years ago when I was treating a guy who had ruptured his Achilles tendon and had it surgically repaired. He was a cyclist and the first active thing he was able to to do was ride a bike with his heel on the pedal. I have also seen a few cyclists with Achilles tendonitis/tendonosis which baffles me. The propulsive muscles for cycling are the big 3- quads, glutes, and hams so why is the calf musculature failing. The foot is a long lever that is solely controlled by the small calf muscle with a very small lever arm, thus the calf is constantly firing to keep the foot in a rigid position and it fails, and if it does not than it is at least sapping energy that could be used for propulsion. Why do cyclists mount cleats over the metetarsal heads? Tradition? I don't know and either do the experts or researchers. While researching this topic I have come across quit a bit of data supporting a change in cleat position from the metatarsal heads to the tarsal metatarsal joint (TMT). I am not going to go into the biomechanics of it here but you can read about it or I am happy to share what I know. Done right it should decrease the peak torque needed to generate a certain output.
Cyclingnews, Steve Hogg, Joe Friel, and Gotz Heine of Biomac have spoke allot about this change and the biomechanics make sense to me but I wonder why no else is trying this?
So I took the plunge and modified some old shimano road shoes to accommodate midfoot cleat position. It is weird at first and took a little while to sort out how much I need to lower my seat but I think I am getting it dialed in. I only have a few rides on the MTB with this set up and have yet to race but I think I am convinced this is superior to ball of foot cleat position. At first I though technical riding and the DH would suffer but so far I have found the opposite, the TMT joint is very stable and requires much less muscle contraction to maintain balance when not pedaling. Anyway, I am rambling now but am very excited to see where this change takes me.
My plan is to race it this weekend at soldier hollow, the bad part is I leave for Long Beach (home of snoop) tomorrow for a bionics certification a will not be on the bike all week. The time off the bike will be good but I wish I had more time on this set up.
