I brought home my new 2013 7.7 this week. *I bought the 54cm but when I got it home I was very surprised it was about 2 inches shorter end to end than my 2010 7.5 (20inch model) *The salesman set me up on the 54cm looked like the right fit for me and it felt ok on my test ride, but when I got home and saw the difference it really confused me.
*
I always thought the old bike fit me wonderfully - not that I know much.*But I know I was always comfortable.

Anyway because of rain this week, I only rode it once for 10 miles. *I did wonder if the new madone frame and all makes it so that the bike is shorter, or did I have too big a bike last time, or do I need to go back in and try the 7.7 in the 56cm size.
