I am going to have a local frame builder build me a Rivedell Atlantis copy. What are some of things I should be stressing to him to make sure the bike is as comfortable to ride as all the Atlantis owners say their bikes are. I would just buy the Atlantis but there are no dealers near me and I hate to spend that kind of money and the bike not fit properly, plus my local frame builder price is about $500 cheaper.
