A reasonable piece of advice, but you left out half the information that would make it useful. Anyone on this forum could be a bike fitter if they wanted to. There is no such thing as a licensed fitter, so how do you separate the people that really know what they are doing from the people that don't? People shouldn't assume professional fitters know what they are doing just because they charge money for it. Some of the computer based fittings require the fitter to attend a few day class and pass a test, but that hardly means they are qualified. There is more to fitting than just putting someone in the position the computer tells them to. The computer needs accurate data. That data includes the information the software designers input which is unlikely to include every possible scenario for every individual to ever ride a bike. It is based on averages, and not everyone is average. The fitter will need to know how to apply some theory behind the fit they offer, because the computer fit may not work. This is what separates a good fitter from a bad one.

What makes you think you are helping him and the others were not? It is pretty arrogant of you to assume that only your post was helpful.
