I've had a couple. The first one I got was a standard 5min bike shop KOPS job. Second one was with a guy that worked with US postal back in the day.

First fit was meh. Second fit made me super, super aero which was great on flat ground, but pushed me so far back that I couldn't generate power in the saddle any more, which meant I absolutely could not climb. It was worth the money & a season of bewildered frustration though, because he took the time to go over all my biomechanical inefficiencies and tell me ways that I could improve on them. I've since changed my position back to just about where I had it, but kept the 130mm stem he put on (was riding a 120). I've also kept up with the work he gave me (stretching, isometrics, etc) and that has helped me tremendously as far as my pedal stroke goes.

I'm not really sure what my point is. I like pie? Yes, that will do.

I do like pie.
