Already checked that, and to make sure, I had the guy at the bike shop show me how to check it easily (setting the bike so that with either pedal at its lowest position, my leg is ramrod straight when pressing on it with my heel; as long as I ride either on my toes or arches, this means my knees never go 100% straight, but I still get my knees working the closest thing possible to full stroke).

I had to go through a few months of physical therapy for the bursitis last year, so this isn't something I try to mess with...
