you'll probably find that any rubber ring will do as long as the size (ID 
and OD) are correct. the reasoning behind this will most likely be because 
of how it calculates how far it's gone. it's like the speedo in a car, if 
you go from normal size tyres to low profile tyres, your speedo will be out 
unless a) u get the speedo reset, or b) you get the correct proportional 
sized LP tyres.
