Update: The Tear-Down
Given this bike’s (rough) condition, it obviously needs every last part assessed for usability and, at a minimum, a thorough cleaning. That means stripping the bike down completely.
The previous owner had noted that the seatpost was stuck. Not just stuck, but “stuck since a few months after I got it”. That’s literally 29 YEARS of stuck. My worst case scenario on this was that it would have to be cut and reamed (or line-bored) out of the frame.
Well, an afternoon out with über-pro Mike at Black Mountain Cycles (and his bench vice, some penetrating oil, and some good local ale) and it popped free without too much drama. Sadly the once very nice Campagnolo Super Record post is probably not re-usable with this much corrosion/pitting (and some cracking on the head parts).
The even better news is that the frame appears free of any really serious rust or other major damage. Just about all the issues are cosmetic. No water or giant piles of rust came falling out of the tubes. No hidden dents. There’s not even any real chainsuck -- probably owing to the double (not triple) chainring setup.
Steve Potts -- whose shop is just down the street -- happened to stop by while we were doing the teardown. He concurred with the positive outlook although it pained him to see his once-beautiful DuPont Imron paint job in this condition. He’ll check over the frame and fork a little more carefully in the coming weeks for alignment and any more subtle issues that might need addressing.
One reason the bike probably held up (functionally) so well is that Steve knew this customer. He designed and built this bike knowing what kind of riding it would get. Evidence of that is how heavy this is for such a relatively small (18”) frame:
Frame - 5lb, 12oz (2.61kg)
Fork - 2lb, 2oz (0.96kg)
Stem - 0lb, 8oz (0.23kg)
- Clean and review every single last part
- Figure out what stays and what goes
