Per my earlier post, I'm pretty sure the Original DA centerpulls were the first part to bear the Dura-Ace label. Also pretty sure they came out before the group, probably 1971 or 1972. I don't believe they were ever sold as part of the DA gruppo. They may have even been discontinued when the DA gruppo with its SP brakes appeared. The only bike I know of that came with them was the Schwinn World Voyageur, although there may have been others. Actually, discontinued may not be accurate, maybe more like relabeled, since, as someone pointed out, later CP's labeled Tourney seem to have been nearly identical.

Bob, all I can do is defer to the master, Sheldon Brown. His site even has the pages reprinted from the book I got!! But, he has the 73 catalog link on his site (and above). The brakes in the 1973 catalog are Dura-Ace and sidepulls. So, the actual pair of Dura-Ace calipers that you have that are identical to the Tourney center-pulls have me stumped. I'm not familiar with Shimano center-pulls enough to really comment. Lou Deeter, Orlando FL

Hi Lou, Does your information happen to indicate when Dura-Ace had used (and then discarded) their "Center-Pull" brakeset?
I have a 1974 catalog which shows the Shimano center-pulls as "Tourney" components: [model B-110 = 47-65mm... Model B-120 = 57-75mm]. However, I also have an actual pair of Dura-Ace calipers, which were identical, and those did not appear with the '74 listings.
Thanks!
