Shimano 105 5600 hubs refurbishing
I bought a pair of 105 5600 hubs cheap. Now I see why.
The cones are pitted.
It isn't readily apparent how to find replacement cones. It also appears that the replacements that can be found are prohibitively expensive.
Can a generic part from another company be used to replace?
It also appears that it may be that with good greasing I can make it somewhat acceptable.
Thanks guys.

I'd take the axle and a cone to a bike shop (once they're open for walk in service) and have them see if they have a cone that matches. What are the hub cups like?

I bought a new hub on ebay when I needed cones for a 6700 hub.

Although I rate this as a desperate measure, you can attempt to grind the cones by spinning them using an electric drill and some sandpaper wrapped around a round object like a pencil or appropriate sized drill-bit. See here:

Only thing is--you are still using the same diameter ball bearings. So the surface is smooth but it may be too large now?

Do a google search for the terms "repair pitted bicycle cones" and read the many posts about this process, including those that say this is a terrible idea. But in answer to your question - no, the cone's bearing surface radius should remain the same so the same ball size is retained.

So the contact with the ball bearing and the other side will be looser because there will be a fraction more space.

I'm having the same issue with an Ultegra 6700 rear hub. I took it apart and found the bearings and races to be in awful shape. I'm planning to take it into my LBS once they open, it's not critical as I have other wheelsets I can use, but I'm hoping it can be fixed.
These wheels were like $300 and purchased at least 5 years ago, so I've gotten what I wanted out of them, but would be nice if there is a cheap fix.
