Golf is a good analogy. An average pro who can generate 115mph clubhead speed with driver and can hit the ball 300 yards. There are pros even stronger...but that average pro...if he plays with a regular stiffness shaft in his clubs, he will hit the ball all over the golf course. Most pros play with XS shafts to control the power they can impart to the golf ball. Stiffness is many things. If you can't flex a bike frame than getter stiffness doesn't matter.
