Ultegra chainrings 52T & 36T plus derailleur RD-R8000-SS (short cage, max 30T) used. It come from a road bike 2022, used for about 2000 M. They will come in original boxes with the new items (the derailleur has a medium cage box). I replaced the drive train completely as I am using a bigger cassette now for better claiming, with a medium cage derailleur.
