I had a custom Seven Ti built about six years ago. The fitting experience was amazing and I even spec'd out the ride I wanted (they used different diameter tubesets). I also had a custom paint job. I got a CF bike three years ago and now ride it most of the time. The two have almost identical geometries and the rides are close. The CF is lighter, feels snapier on sprints, and seems to climb easier. This is when I used the same wheels on boats.

It made me realize how most people don't need custom, unless your body dimensions are unusual. Custom sounds nice but the reality is it's not necessary. Plus technology keeps changing. I know I wouldn't want by best bike to be 10-20 years old considering what has happened with cucling over the last 10-20 years.
