I was cured of the notion that rubber under a clamp was a good idea in 1973 as I was riding down Highland Avenue into Hollywood to go to high school one day. My Soubitez bloc generator vibrated it's inner tube frame protector loose (teenage logic--a rubber shim under the clamp but still had the ground screw through it to make the light work) and my attention was drawn to the plinking sound of the two bolts on the generator's clamp bouncing off my front spokes. A safe and controlled stop was achieved before the wrong end of the Soubitez brought me to an airborne, uncontrolled stop! If a clamped part has any weight or load on it at all, I won't tape under it at all.
