Most recent. I wanted the old style chainring on it so found a free set in great condition. Also found a nice 70’s seatpost bolt with the “S” on it to install.
I was having trouble with the seat post slipping so cleaned the tube of grease, cranked down on the post but it still slipped on a ride. Pulled the 25.4 alloy post which was the same size as the steel original. The ID of the seat tube was 25.6 to 25.7. Found a manufacturer shim in my parts bin and put the whole thing back together. Nice and tight! No slipping. Will probably order a 25.6 if they make it.
Got the post ordered and it has arrived. Always want to get rid of shims if I can.
