Sedisport was the
#1 chain on the market, at least for all but low-level bikes, for many years. It worked with everything that was current at the time, including 5, 6, 7 and 8-speed applications.
Sedisport chain wears well, which further increased it's popularity with serious riders, and seemed to get along well with every style of cog teeth prior to HG.
Sedisport chain did not work properly on the new HG cassettes (that first appeared in 1989), and Sachs/Sedis' subsequent updated road and mtb chains seriously lagged Shimano's chain developments in performance for over a decade until Shimano's patents apparently expired in the early 90's (after which SRAM's 8 and 9sp chains started featuring bulged sideplates in the style of Shimano's).
