Yes very nice, I loved the earlier pink blue and white Chateaux d'AX version. I think a special seatpost is needed for these frames.
Yes I must admit , i have a soft spot for the team pink/bluey purpley/white colour scheme . They do occasionally come up in those colours on Ebay , but normally blocks of the purple on a pink frame, not the fancy angular team paint job I prefer . The seat post from what I remember fixed the same way as a quill stem I think . It looked a lot neater than the conventional way .
Recall going to the 1990 Wincanton Classic in Brighton , the first team car I saw was a Chateau D'Ax Citroen CX estate
with a roof full of the lovely bikes .
