Rule of arm, so to speak
 
I just learned this, and I wonder how useful it is to others.

I put my arm put on the saddle and touch the crank. If my the tip of my middle finger is about at the crank spindle, the saddle height is just about right.

What? Can it be that simple?

The average person is as tall as they are fingertip to fingertip. If you are average, your measurement might be useful to a lot of people. If you are like me (over 6' between outstretched fingers and only 5'10") not so much.

Hehe - I read not long ago that if the distance from your saddle tip to your handlebar is elbow to fingertip, your reach is about right. I think these "rules" are so generic that they're hard to prove or disprove.

I know this one doesn't work for me.

I'm not saying people ought to live by the rule of arm. I'm saying that it can be -- CAN BE -- useful for some of us, some of the time.

He who lives by the force of arms will perish by the same!
