Not sure if I need a body mechanic or a bike mechanic. Right knee about one inch closer to top bar, often touching it. Also noticed problem on just retired mtn. bike but ignored as new bike was on the way. Had to remove stuff bag hanging under top bar as shorts rubbing it causing unnecessay wear.
Confirmed seat centered, played with cleats and seat up/down. Did not have this problem when I stopped riding 5,000 mi per year 23 years ago.
