Hi... I have an interesing bike fit problem.
I have two bikes. The old one, an 80s steel touring setup with clips + straps, I've ridden for a few years. I've found moderately comfortable saddle positions on it, though even in the best I seem to start getting a bit of pain in one knee or the other after 100km or so (but I've managed a 200km+ day and survived with stretching and careful pedal strokes, kind of).
My new bike is a racer with clipless SPD pedals. By luck, I seemed to find quite a good saddle position straight off and I think I can do about 100km without real discomfort (haven't tried anything longer yet).
I still ride the touring bike around in the city, and take it camping occasionally, so I'd really like to find a saddle position that is equivalent to what I've got on the road bike. Most especially because I don't want to strain my knees as I switch between the two of them.
The racer has 172.5mm cranks; the tourer has 170s. And of course the foot position with clips and straps is a little different (probably further forward) than what I get with clipless shoes. The tourer has a slightly bigger, squishier, saddle. Anyone have a good idea of how to go about calculating the closest thing to a biomechanical equivalent position on the tourer?
