Campy Delta brakes were about the worst component Campy ever made. Uselessly complex, poor performing and a nightmare to set up. Avoid at all costs. The Record Delta bakes could be made to work with enough time and expertise. The lower line Deltas were hopeless.

The Chorus single pivots (These are "Monoplanar" if I interpret the picture correctly) are as good (or bad) as any other single pull. They work ok but new double pivot brakes are better.
