Pros do a lot of things I would never do. Just because "a pro" who rides 20,000+ mi/year is comfortable in a certain position does not mean recreational (or even local racers) who ride maybe 5,000 mi/year will be. Fit is an individual thing and generalizations are decent starting points, but in order to truly develop the best fit, you must work with a fitter in person. Not over the internet and not by looking at pictures of "euro pros." Plus, it has been mentioned that pros generally ride frames that are "too small" for their heigh meaning they use very setback posts and long stems. If they sized up, they could achieve the same position with less setback and shorter stems.
