When you get done, with your professional fitting don't expect a perfect fit..

It's such a personal thing.

I got fitted once, It was free with my new bike purchase. I carefully watched the guy do things, then he wrote down measurements where ever he could.
The PC churning away while I pedaled was kinda cool. It was charting this and that,,
Personally I think the PC was all show for me, he rarely looked at it,,If at all... LoL

Seat post height and Seat position Fwd/Aft was achieved with the good old Plum line over my knee cap down to the pedal axle with crank arms level,, both feet checked.

Handle bar width was simple,, He had me do a few push ups then measured the distance between my hands, center to center of my palms,,,
Told me this was best for opening up my lungs.

It all felt close, very close,,,but,,,
I raised the handle bars 3/4" and It was better.
I moved the seat back 1/4" and my knee's no longer hurt at all,, I could hammer all I wanted now

The cleats,,for me was Pedal axle 1/4" behind the ball of my foot.
I went back to the guy about this, didn't want to do damage to my feets..
He said It's fine because I ride Shimano's with a platform,,Mountain pedals ya know..

All these small adjustments I did for my perfect fit.. BUT I had The pro fitter's measurements to work from..
That was three bikes ago,,, I have not needed anyone's help fitting any bike since.

I Ride, I crash, I bleed, I heal, I ride, I crash, I bleed, I heal, I ain't no Roadie,, I do It In the woods as Nature Intended..
These days I crash much less, But Still,,, I love it so...
