My LBS has a 2006 58cm for $970.00 out the door. After I test rode it, it seems a little too big, but was not that bad of a ride. I'm 5 11 1/2 with an inseam of 31-32".
Is it really that big of a deal from a 56 to 58? I was thinking about buying a Jamis Aurora, but the LBS said than the components on the 520 is better than the Aurora and that I should go with the 520. Should I sacrifice size for components? If you are between two sizes, should you go up or go down?
