thats what i had heard before, and why i asked about just putting it up front. i also happened to pick up a gt for $5. i think it was some sort of a hybrid bike with 700 wheels, but wider and knobbier tires. swaping the front wheel will be a piece of cake. i'll probably wait until i start noticing a problem though (hopefully the first problem won't be a major one).
