Wow. I figure if I get 10,000 on a ring I did real good. Some of the cranks I use you take what rings you can get and they last a lot less.
My wife had an old set of Campy Nuovo Record rings she used for 35 years. Rode very regular and rode all weather but all short distances around town. She also weighed under 100 pounds most of those years, with a max of maybe 105. They looked maybe 1/4 used up. I took over those rings and they were done in a season. I can't ride as if I weighed 100#. Also never met anything that lasted like old Campy.
