I thought I wanted a Trek and even convinced Trek to send one in my size to my bike shop that I could try. Brought it home for a week and just never felt much for it. I discussed my concerns with the shop owner, but he knew more about what I needed than I did and never really listened. I tried a cannondale, it was okay. I tried the specialized and liked it. I wonder how much it had to do with the fact that I ride past this shop all the time and the owner was familiar with me. He really listened and spent a lot of time fitting me. He also listened when I said I liked the bike but something was missing. I knew when I threw my leg over that sweet steel ride of his that I was in love. Everyone said I was crazy but I spent every cent I planned to on a steel bike. I haven't regretted it for a minute. Funny thing is, when I starte dbike shopping years ago this same person tried to steer me towards the steel.
I guess what I'm saying is find someone who knows the industry and is willing ot get to know you and your riding style.
