I'm looking at getting a first road bike. Yes, after all these years of commuting, finally (approaching 50 :?: ) decided to see what fun I can have with a proper road bike. Have been looking at the Specialized Allez Elite on internet (but can't find one to try for feel locally, and anyway, would be looking at a 2006 model as £500 is my budget). Is this a reasonable bike to aim for? What size should I be thinking about - I'm 5' 8".
