I purchased a 1988 steel Italian bike with Miche hubs and a Suntour 6 speed freewheel- the 2 prong type. The wheels are rough when spinning on the axle so I am working on servicing the hubs. I am wondering where I might get replacement cones as they are rough, one is very damaged, the other 3 are slightly marked where the bearing are supposed to roll. The cups seem to be ok. The cones are standard 5/16" and 3/8". I have seen some unbranded on ebay. Are they all the same size-wise, i.e. the angle of the curve etc.
BTW I am based in Europe.
