Have you noticed that short stems tend to feel good? SHO is one possible reason.

SHO stands for steering/hand offset. How far are your hands in front of or behind your bike’s steering axis?

In this diagram, the mostly vertical line shows the steering axis. That’s the imaginary line that passes through your fork’s steerer tube, through your headset cap and into outer space. If your head angle is 69 degrees, your steering axis is 69 degrees.

The horizontal line runs from the steering axis to the midpoint of the grips. This distance is SHO.

Your favorite SHO (if you have one) is determined by your riding style, personal preference or (most likely) what you’re accustomed to riding. If you have a favorite handlebar/stem combo, you might like the SHO they create.
