I bought this bike a couple of months ago. I just found out that this bike is a tad bit small for me. I should really have gone for the 52cm. I'm not sure what to do. I don't think bike direct will be eager to change it, especially since they've come up with a 2011 model. I couldn't find anyone selling this bike used so I'm not even sure what price I should advertize it at if I sell it. I don't want to lose too much on this deal. Any advice? Thanks in advance.
