I've got a 1985.9 model year
Hi.
Finished the headset, with new balls and grease, and it's nice not to have that moving.
Also did the bottom bracket Saturday, and took it for a ride on Sunday. That also feels good, and checking post ride I didn't have any play in the cranks the way I previously had.
Is there some trick for getting the fixed cup really clean without removing it? I felt pretty good about how it ended up, before regreasing and reassembly, but it was a pain.
And, I don't know how common it is to the Ironman family, but my bike with an N6... Serial number, and SIS shifters, has the Tange bottom bracket listed for 1985 models. As far as I can tell, everything else lines up with the 1986 components in the Ironman spreadsheet.
