I got a Serotta pro bike fit a long time ago from Bert at High Gear Cyclery. Maybe 9 or 10 years ago? Was right after getting the Ridley Excalibur that I still ride and its about 11 years old now. Was around $120 if I recall but took flexability into account. He flipped my stem up and put the saddle back as far as it will go. Only change is flipping the stem back down after I got more comfortable with it. Was worth the money, I think. Should ideally get it done again, but have been too cheap to do it. Single income supporting wife and child also has something to do with it.
