A few days ago some dude came into the bike shop with an older road bike (possibly 80's or early 90's) with some really nice and unusual looking Campagnolo brakes. Of course They were very elegant looking, But the thing that was most characteristic of these brakes was that the head of the pivot bolt on both front and rear brakes was shaped like a small spike, I presume to make the brakes more aerodynamic.

Does anyone know what I'm talking about?
