Athena only had Monoplaners in '94 and '95. Campag put groupset names on components from '95 and '94 Athena had black O-rings on the cable adjusters and one-piece brake blocks & wheel guides.
The only other groupset to have Monoplaners pre-'95 was Chorus: 1st Gen. had white O-rings and wheelguide covers; 2nd Gen. had black O-rings and "naked" wheelguides.
The shape of the ends of the caliper arms is also different between 1st Gen. Chorus and all other variants.
+£75 for Chorus, compared to around £50 for Athena. These have gone up a lot over the last year and good condition examples, like yours, are sought after; fast catching-up with Deltas, presumably because they actually work...
