I confess that fifty years ago I believed the hidden hub rule and the saddle-nose-to-handlebar fingertip rule until I discovered that, for my anatomy, on my bicycle, it was impossible to find a comfortable position that reconciled the two.

How upright do you sit? How long are your arms? How long is your torso? How long are your femurs? What is the rake on your fork? What is the head angle? How much bottom bracket drop?

These old rules of thumb came about because they seemed to work for many people, but there are many exceptions to these rules.
