>>>>The old Sedis chains always shifted very well and are still available as Sachs. There are other good chains, but I found these to be inexpensive, last a long time and shift really well, so they're my favorite. Stevan Thomas Alameda, CA<<<<<
I second that emotion.
The PC 48 and PC 58 chains are inexpensive, work very well and look appropriate as well. And you don't have to use the snap-link if you don't like the look. I have used them successfully on many vintage bikes.
Anyone remember back when Winning magazine used to do a double-page picture and profile of a pro team bike each month? They would list each component and, more often than not, the chain would be the lowest-cost Sedis! I sold many a basic Sedis chain by picking up a Winning mag and saying "see what the pros use".
