Re: Will these handlebars hold up?
I'll try to explain simply how the lead shot works. Vibration is motion. Think of it as quick up and down motion. The lead shot has mass to it. That will serve to slow down that upward motion. Then when the downward motion starts the lead shot will rise. Think of a falling elevator. If it goes down faster than the force of gravity would cause it to, the shot will apply force on the upper surface and retard that motion. This will continue with every cycle of the motion. The shot will move as it's mass is affected by the vibration, but it will retard the next return motion by it's mass contacting the top of it's space resisting the return motion.
