Thanks all. Wheels mfg. doesn't appear to have what I need, though Loose Screws has a complete axle. That, of course, implies shipping, and though that worked well when we were in Merida, mail to the pueblos seems to simply disappear. [MENTION=190941]jimmuller[/MENTION], I tried bigger bearings, with poor results. I could change out the entire hub, but that would mean re-lacing the wheel. That is likely the route I'll go though. No idea what became of the original cones; most likely trashed like every other bearing on the bike, except the cups seem to be in decent shape. Even the cartridge bb fell apart upon removal. The PO is an avid cyclist, with a bike in Italy, and others throughout the world, so I naturally thought it would be well maintained. The headset bearings were dust. Etc.
Thanks again for reinforcing what I was trying to find a way around. No time like the present, eh what?
