Richardson Bike Mart at 1451 W. Campbell Road in Richardson. Carroll Mayhew is the guy who went out of his way to help me. I was there on a Friday and we ran out of time. He came in on Saturday which was his day off just to continue helping me. He knew his stuff about bike fit although he has only done supported tours himself there were two other salesmen there who had a lot of experience with loaded touring and they happily gave their advice as well.

If you go there and talk to him tell him the guy who drove from Oklahoma City to buy the 520 recommended him. I don't get anything out of it if you do but I would like him to know that I'm recommending him because of the great sevice they gave me. PM me and I'll give you my name if you like.
