I bought a bike a year ago...never got it fitted. I hear it is a good thing to have done.

In terms of riding position, what should I look for? Does anybody have a diagram to reference, or is more of a comfort thing? I'm interested in angles i should look for....like how much my knee should bend etc.

The only real issue i have is that my levers are a bit of a reach when im in the drops (and i have to lean a bit more than necessary when im holding the horns)....which makes me conclude i need a shorter stem.

How much shorter though is my question? From this, arise other questions like are my shoes aligned properly etc etc, seat too far back?

Any advice (I'd rather do it myself...or at least understand what to look for)

Does that make sense? Or did i just ask a ******** question?
