So I am in search of my first road bike. I've been to a few shops and have been measured- I have short legs and a longer body- so I'm looking at a 51cm from what I've been told multiple times. I've ridden a few bikes and feel like I'm shopping for a car- whatever price range I give them, they always seem to start me well above that. I'm trying to spend under $800- I'm looking to get a taste for cycling and I'm afraid that I won't catch the bug so am not ready to invest $1000's yet. I've ridden a Giant Defy, and Jamis Sport and a Raleigh- not sure of the model- and I was just looking for recommendations from the community. I know that I should go for carbon in the forks if possible and that I need to be comfortable with the shifting componentry, but please, point me in the right direction. If you were just starting out and had $750 to get up and running, what would you do?
