Thanks Ladies for the info! I had no idea the TT would be longer than the dolce's 54"! In any case- I went ahead and bought the bike...and hope the top tube isn't too long (or that I can make enough other adjustments to make it work). I did a quick test ride- and for the most part it seemed ok. I found the bike on craigslist and it was such a good deal that I knew I couldn't wait or it would be gone.
I can't wait to take it on a ride!!! I'll report back after I make adjustments and get a ride in. I'm so happy to have a new road bike- so far I love it! I showed it to a friend and she instantly had bike envy.
