I am a big fan of functional bike fit, i.e. give me a few wrenches and my arms, hands and legs to use as measures and I think I can set up pretty much any bike to work well for efficient riding in a matter of minutes. Yes, I know this is very old school and frowned upon, but that pretty much describes me!

Seriously, as far as saddle position, height and tilt a reliable final measure for me is balanced and controlled riding hands free. If I can't sit up and steer fairly relaxed hands at side, something is wrong with the set-up. It's a functional sweet spot for saddle position (road bike).

OK, I suspect this will be considered heresy by some on this board -- educate me as to why...
