To me, fitting is all about comfort..everyone has their formulas they use...none of which means anything unless youre comfortable.
At first, people will start off with a more up right position...have the stem flipped up and have the hoods higher..once you get a better core, you can stretch yourself out, get more Aero.
I know its tough to watch these guys riding the in the tour and all...but these guys have YEARS in the saddle...yes, their seat it 4 inches above their handle bars, but can we do that? I cant...thats for sure...
Just ride...standing up, sitting down, RIDE...
cept road...man road is boring to me...sorry...i did try it though, i did it for a few months....i was just WISHING for a jump, some dirt, and some more jumps.
