Don't feel bad about taking your bike(a few times if need be) back for readjusting. They should expect that it happens with all new bikes, everyone needs to tweak it until it's perfect. You may even have to start asking around and find a really great person to fit you. It will be worth the extra money down the road in not stressing any joints. My guy watched me spin for a while and notice my right knee naturally pointed out but my shoe placement fought that natural tendancy and he fixed it and I was SOOOO HAPPPY!! Best 60.00 I spent since buying the bike.

Keep us posted.
