So many moons ago that no-one, even at the factory, seems to be able to put a definitive date on it, they did make a brake that has some things in common with a centre-pull, in that it had two pivots and a straddle - but the straddle was two solid arms, with a central pivot, pivotted to the two brake arms, rather than cable. There is a solitary piece in the old reception hall at the factory. I don't even know if it was ever a production item - it may have been a prototype for something that was never commercialised in that form ...

I'll try and remember to ask next time I am there. The only person likely to know, though, is Valentino Campagnolo, Tullio's son ... and although he's in the factory most days, he's not a man you just casually drop in for a chat with!

The way that brake works is in contrast to how the Delta works, which strictly speaking is not a centre-pull but a type of para-pull, where the vertical compression of a diamond-shaped set of four linkages pushes two horizontally-opposing pivot points outward. The brake arms are pivoted to these horizontal points of the daimond and below the diamond such that the brake blocks, at the far end to the pivot, are forced towards one another ...
