Well I didnt get what a freewheel was until today when my grandad explained (he's not that old) but we couldn't work out what a front one would actually do, also lie I say im having a pain taking the gears of my phase could I just run a rear freewheel instead of a single speed kit ? Or would I have to have both or would it be better using one of these front freewheels? It's all very confusing
