Hi, I'm a 24yr male specializing in riding time trials for the last 5 yrs or so. I've had a lot of injury problems over this period mainly with my left hip and right knee. Recently I went to a specialist bike fitting centre to see if they could help prevent further injuries. They noted my left cleat was set so that my left leg was much further away from the centre of the bottom bracket than my right. Then when testing my hip flexability they found that whilst my right leg could be brought up to my chest comfortably in more or less a straight line my left leg has to move in a line that takes it away from the centre of my body towards my left shoulder. This appears to be the reason I have been riding in this position as I set my cleats up where I felt most comfortable. I also ride with my seat rotated slightly to the left for similar reasons. I would like to know whether this is likely to be a physical imperfection that I have in my hips/pelvis or if it is more likely to be a functional problem such as a muscle imbalance or twisted pelvis perhaps? My left thigh appears to be slightly longer than the right, could this also be due to the problem with my hip? Also, when I stand with my feet together my knees have a large gap between them and my right shoulder is slightly lower than the left.

From what you say you have obvious asymmetries of function at work. As to your query re the root causes, there is a multitude of possible causes and interactions. The best money you could spend is to find a quality structural health professional like a good physiotherapist, chiropractor or similar and have yourself structurally assessed. If you get back to me with the results of that, then we have some information to work with. We can go from there. In cycling like every other sport out there, the better and more symmetrically we function, the better we perform and stand up to any given training load.

The Merckx is 1 degree more relaxed in the seat tube angle and 5 mm shorter in the top tube. Off the top of my head, that 1 degree of seat tube angle should equate with 9 mm give or take a fraction at the centre of the intersection of top tube and seat tube. That means that if using the same seat and seat post, you would have to move the seat forward in the clamp 11.5 - 12 mm from your Gios placement to achieve the same seat setback behind bottom bracket as you have now when putting these parts on the Merckx. That distance is based around a guesstimation of a typical seat height on a frame of your size. That 11.5 - 12 mm if factored down to the top tube gives the 9 mm or so that you are effectively shortening the top tube. Add to this the 5 mm that the Merckx is shorter in the top tube and you would need, rounded up, a 15 mm longer i.e. 150 mm stem to achieve the same position on the Merckx as you have on the Gios.
