How do you alter a bicycle safety helmet to fit different sizes of head?

Answer:

Depends. Some have padding in the inside that can be either removed or added to adjust size. Some have a strap at the rear that can be used to adjust for head size. In extreme cases parts of the inside shell can be sanded down to match the lumps on the rider's head for a custom fit.
