hmmmm, I have also thought about that point IndySteel... it is true that none of my injuries were related to my knee - that I know of. My recent knee problem had nothing to do with the bike

I am still working on a more consistent starting technique, and when I am happy with that I will make the change. The seat post is getting raised every few rides now so I don't want to introduce something new until I am more comfortable with the new way of doing things.

Some of that is probably nerves - and it isn't about clipping in/put - it is the whole injury association. I will also discuss this with Jonathan and see what he thinks about the wisdom of moving to another kind of pedal..
