Still have 4 out of a half dozen Sedisport ultra 7 chains that I bought for something like $7 apeice years ago before I stopped riding. I replace them every 2 years. They make a 13-25 ultra 7 freewheel in Taiwan somewhere that I bought for cheap. Some of the reviews on it are critical of the QC / quality but this one seems to be alright for my old steel bike. Will replace them both this winter.
