Victory gruppo. Often pooh-poohed as not as good at NR and the like, but good stuff nonetheless. I think the calipers are the same as the upper level Campy for this time period. Clean it up and you will have a nice ride. The BB is Cinellli. I would rather have the Victory than 105, but that is my preference.

EDIT: FWIW, I have seen only one other Gib and that was a time trial bike on display in a bike shop located in Silverdale, WA
