I’ve got an Eisentraut A frame bike that I bought way back during my college days in 1977 at Champaign Cycle in Champaign-Urbana, IL. It’s mostly DuraAce (crankset, brakes, hubs on a pair each of clincher and sew-up rims, Crane derailleur) and Campy pedals. It has sat virtually unused since the early 1980’s and, although it is certainly okay to ride now, I’d like to tune it up a bit. I’m not a serious biker/racer, mostly just recreational riding.

One problem is that the front chainrings are more appropriate for flat Illinois than hilly Anchorage (51 and 42 teeth). Can you still get chainrings for a 1970’s era DuraAce crankset? Or does the entire crankset need to be replaced?

The rear freewheel also is original and may need replacing, but I don’t think it will accommodate more than 5 gear rings. Are these still available?

And the pedals probably need to be replaced. I think they were near the top of the Campy line at that time, but they are pretty beat up and I got rid of my old-fashioned cleated cycling shoes long ago.

The fellow at a local bike shop here wasn’t very optimistic about working on it (he actually suggested that I hang it up on the wall as a memento of past bikes I’ve owned), but the frame is really nice and the bike has a lot of nostalgic value for me. I’d be grateful to get feedback from other readers on the best way to tune up this bike.
