Agree with what the others have said. See if the LBSs will let you do an extended "real" test - do one of your normal rides of at least 20 miles if you can. When I narrowed my most recent search down to 2, both shops let me do this, although one (the one I ended up buying from) was much more accomodating about this than the other (I blame the new young manager who seemed to have little customer service experience
). After my test rides, I knew which bike felt soooo right and which one didn't quite measure up. Good luck and happy riding!
