Re:
would say DeltaV
Killer V got classic 1"1/8 headtube
In 95, the F1000, 700 and 600 were available in 2.8 series frame like Tinker Juarez or DeltaV. Cannondale adapted the Delta-Vdesign to no suspension frame called Killer V.
But in 96, the catalog showed the front suspension available with the "KillerV style". So, pending the built year of your bike, it would be a DeltaV or a KillerV
