Bike fit / correct riding position

I don't know what that means. I think for my height I have fairlong long body parts hanging off my barrel torso. Basically, 165mm cranks are mean your knee doesn't go so high at the top of the pedal stroke so for me it reduces hip squish. I have illiac artery endofibrosis but not bad enough to go for surgery so short cranks are good for anyone getting into TT positions, aero road tucks or generally riding faster/flatter. Upright touring bike scenarios need not apply.
