Have never known an exact year for this change. Have thought of it as taking place in the mid-'80's. From what have observed would make guesstimate of ~1983-84 for the transition.

The manner of the cycle's kitting is a bit of a dog's breakfast. A nominal KAS team bike would not have left the works with anything like this kitting. Some of the obvious non-original bits are chainset, stem/bar set, saddle pillar. From what can be seen in photos chainset appears to be a Zeus Gran Sport or Criterium triple while one would have expected a Zeus equipped machine to be fitted with a Zeus 2000/2001 double.

Rear mech looks to be Campag SR while front mech appears it may be Campag NR. Yet headset appears to be Zeus Gran Sport (part of Criterium road ensemble). Machine wears a MAVIC sponsor's transfer yet MAVIC was offering a full road ensemble by this date.

One possible explanation for the odd assemblage of bits could be that someone obtained it as a bare frameset and built it up with parts to hand.

Frame constructed of BOCAMA Competition 78 lugset.

Forum may have some members who recall details of the KAS team machines of this time who will be able to post.
