A flawed concept. But beautifully executed.
Nostalgia has a funny effect on how we choose to remember things. And, as I have said before, there are some things in this world that are so beautiful to behold that we forgive the fact that they didn't actually do their job all that well. In my nostalgic, cyclocentric world, Campagnolo delta brakes have been a shining example of this.
The following are what I understand to be the 5 standard incarnations of the Campagnolo C Record delta brake calipers. Missing from the lineup are the 2nd generation calipers with the Campagnolo logo etched into the faceplate (see my previous post).
2nd generation (printed logo on faceplate has faded)
The first generation delta calipers appeared in 1984/5 but were soon pulled off the market after reported failures (in the interim, they were replaced by the Cobalto brakeset). Delta calipers then reappeared in 1986/7 and lasted until the end of the C Record era in 1994. More information in my first post (2008).
An iconic piece of cycling history.
