I have read a lot about bike fitting and I still don't have a clue about how to fit a bike to a rider. Are there any threads on here where a short video of a rider is posted and then analyzed by qualified fitters. This would be helpful and maybe then I could at least have a few clues about what to look for in a fitting.

I know that the fitness of the rider has a lot to do with how any bike fit will work for the rider so maybe several videos of various riders would be helpful.

My bike fit probably needs to be tweaked and I would like to know what to expect if I raise the saddle too high or if I have it too low. All I can do at this point is to make a small change and ride for a while to see if I like the change. It just appears to me that this bike fitting is an art and not a science and trial and error is the only way to make any progress.
