In the late 1980s, at a time when Campagnolo was still hanging on to their woefully outdated derailleur designs and losing the technological battle to Shimano and Suntour, a new component line was introduced. Dubbed "C-Record," this gruppo was perhaps the pinnacle of Campagnolo's fanatical devotion to aesthetics.
Perhaps the most unique component on the new C-Record gruppo (released in 1986) was the Delta brakeset, named for the shape of the housing covering the complex inner mechanism. Inside the housing was an articulated parallelogram mechanism that moved the brake shoes toward the rim by expanding outward and pushing one the upper portion of the brake arms.
(Note: Although Delta brakes were first sold in 1986, they were originally shown to the public in 1984--for about an hour. Prototype Deltas were unveiled at a trade show that year, but were quickly taken down and removed from public viewing.)
