4 Bolt Shimano Chainrings (5800/6800)
Posted: 07 Feb 2020 21:13
Anyone got any 4 bolt 110bcd Shimano chainrings for 105 (5800) or Ultegra (6800) lying around? Don't mind too much about ratios, ideally 52/36 but happy with 50/34 or 53/39 as well. Simply for a cranklength test for bike fitting purposes... Cheers
