Right now I'm riding a 2007 Jamis Ventura Race 54cm, stock components that fits me fine: http://www.jamisbikes.com/usa/bikes/...nturarace.html

I'm interested in buying a used 2005 Specialized S-Works E5 54cm Frame

Do you think I'll be okay on dimensions? Or what should I measure on each of the frames to make sure that I'll still have a good fit on the E5 54cm, or do I need to go smaller with a 52cm?
