Hiper parts

[Fralick #81]

Anybody know where to get parts for hipers at? Ive searched and just cant seem to find anywhere that has o-rings for hiper wheels. I would get one some where else but im not sure on the size, anybody know what size o-ring it takes for a 10 inch front wheel?
Thanks,
Jon

Have you tried to call Hiper ? I think the # is 1-800- GOHIPER
