Professionally polished and then clear powdercoated. Powdercoat has helped keep the polish overall pretty good, but heel rub etc has taken it's toll... What might be better is to take the powdercoat off and just keep them polished with autosol or the like... SS On-One chainring is in fine nick, these are stainless steel I think, so last forever... asking £50 posted for these
