Thanks, Juvela! It didn’t look like any sort of Campy associated product. I wonder what it says though??
I’ve rebuilt all of the bearing surfaces ( with the exception of the headset), and fitted a new chain. Planning on a short ride tomorrow to see how it all works and feels. I’m not going to push it too hard on the ancient sew-up tires though.... Does anyone have a recommendation on inexpensive replacement tires I might fit to replace these?
