Need help with cones for Ofmega rear hub
I was repacking the hub bearings on my 1984 Bianchi Nuevo(a!) Racing, and found that the cones were destroyed both front and back. I was able to get some campy front cones for my Ofmega hubs (nine 7/32 bearings) but am having a devil of a time finding rear replacement cones. They are 10x26 with nine 1/4 inch bearings each side. I was told by a number of people that the Campy rear cones work, but the local shop had 3 or 4 different types of campy cones and none fit. All had the problem that the narrow end of the cone was too wide to fit inside the circle formed by the bearings. Looking at the original cones, the cone was ground such that on the narrow end it tapered almost to a sharp edge, whereas the Campys seem to have more meat and be larger on this end.
Anybody have experience with this? Are these cones really different, or did my local shop show me the wrong parts, and should Campys really fit?
If Campy's don't fit is there another solution? I don't want to just buy something off I'net or ebay and find that I have the same problem that I had at my local shop.
