mateo, I think you hit it. When I was looking for a new bike, a Cannondale, it had flat pedals an they felt pretty good, so I bought some and put them on my Jamis touring bike and I pedaled harder that I ever did and didn't have any pain at all. So now I knew I had to get a different pedal with a larger platform and that's how I ended up with the M424. I bought a Specialized Roubaix and put the M424 on that as well, so I may have to change them out. I looked at some road pedals and it looked like the platform on the M424 were bigger. I'll have to look around. Many thanks again, I moved this saddle so many times I think I wore the seat post out.
