Howdy folks.

I think there is more than one version of the Competition, but I am wondering about the ones that look just like 2000s and about 2000s. Would they have been in use in the early to mid-70s? Perhaps a better question, would they fit it/make sense with a Stronglight 93, Simplex Super LJ and Retrofrictions (the older sun style) and Normandy Luxe Competitions? I have a Bertin that I think is from the early to mid-70s and was going to use Racers, but now I have both Competitions and 2000s and wonder about using them instead. Thanks :^)
