Oh, they are fine just now, but I'd just like to know, for future reference. An ounce of prevention and all that... I repack my hubs before anything goes wrong, then there's no damage to the races. Once grit gets in, or water, it's all downhill, but with regular servicing they can last ages. I just wondered if the same was true of the new BB's, or if they are just disposable like the cartridge BB's. I don't like disposable stuff.
