Best looking or best working? My comments will target function over form.

For my money, the best seventies side pulls would have to be the Shimano Dura-Ace stoppers. And, timely though this might be, I just got a set of Dura Ace side pulls in the black anodized finish. The brakes match the Dura Ace high flange black anodized hubs and go nicely with the black anodized Suntour Cyclone Barcon actuated transmission. Campy seat post, Stronglight 93 triple cranks - sorry starting to ramble cause I am excited about my new, but way too big, Holdsworth.

The best in the eighties, Campy's (don't even know what they are called but the pull is easy and the stopping power is above average)...



As far as looks go, those Campy stoppers are it!
