Afaik the Carbone '9' refers to 4 off seat stays (constructed in two sections) 2 chain stays and 3 main tubes. Alloy forks were Vitus's 'thing'!!
Also the bottom bracket is probably chamfered at 45 degrees to take a Mavic/Vitus sealed bottom bracket. I remember we had a tool to do this in the shop, but that was a very long time ago...
