Question to all: When did the Campy SL pedals with the black aluminum
cages first become available? Old race photos might give an idea,
although pedals usually are hard to see. Of course, as Chuck pointed
out, racers might have parts that might not go on sale to the public
for a few years.

So why did Merckx/Colnago go to Pino Morroni for this stuff, when it appears Campagnolo/OMAS were working on similar projects already in Italy? I don't doubt any of what you say, but I wonder who inspired whom... Of course, it also was "in the air," as the 1970s lightweight fashion was getting under way. Ocana used a ti Speedwell in an early 1970s Tour, didn't he? So it might not surprise if two people work on similar projects. -- Jan Heine, Seattle Editor/Publisher Vintage Bicycle Quarterly c/o Il Vecchio Bicycles 140 Lakeside Ave, Ste.
