More revs

A worn belt goes furthur into the pulley, so the front pulley has to turn more for a given distance. Of course this is difficult to see due to the variable ratios, but, will be more noticed at high speed when the front pulley is at it's limit of travel. It will degrade high speed performance. Let the belt get excessively worn and your belt will slip and the RPM's will be really high for your speed.Or you might not move at all.
