Yes: C-Record as a whole, was Campag's answer to Shimano's AX groups.
However, the feature that differentiates Monoplaners from standard single pivot brakes, the intersecting caliper arms, was an attempt to resolve the problem of flex when the brake was applied.
Just to add to what agent Orange wrote:
- '88-'91 Chorus series 1 (white cable adjuster o-ring and wheel guide rubbers).
- '92-'93 Chorus series 2 (black cable adjuster o-ring, "naked" wheel guides, shape of the end of the caliper arms revised, brake block holders inherited from Record/Croce D'Aune).
- '94-'95 Athena (as per Chorus series 2 but with an all-in-one, rubber brake block/wheel guide).
- '95-'97 Veloce (as per Athena, but with an all metal cable adjuster in '95 only and cartridge style brake holders in '97)
- '96-'97 Mirage (as per '95 Veloce, but with a domed rather than pointed nut to secure the caliper arms).
NB From '95 Campag labelled all components with groupset names.
The "false" Athena Monoplaners, Agent Orange referred to, are D500 and pre-date Monoplaners. Although the shape of the caliper arms is the same as Monoplaners, the arms sit one on top of the other instead of intersecting; ie they are conventional single pivot brakes.
