Should have said "before everything went V-brakes" You've always got those transitional periods where both techs are existing side by side.
I don't recall anyone being in a big rush to convert their canti bikes to Vs, unless you were one of those guys who couldn't get the hang of setting up cantis correctly

I held out because I had badass cantis; DiaCompe 987s with Straddle Rods on one bike and Control Tech "Jimi's" on the other
