hi, I have a 1997 Cannondale Killer V700 and I’m looking to swap the fork. If I want to install a conventional 1 1/8" threadless fork, will this specific reducer work for my frame? Also, is the reducer the only part I need for this conversion, or are there other components required?"

You would need these reducers, and then a traditional External Cup 1-1/8 Headset. So long as the fork you are putting on there has a Straight Steerer Tube (Likely on a 26in V 700), you'd be all good.
For headsets you can use, try the following in the description for a traditional External Headset: EC34/28.6 - EC34/30

The Problem Solvers Head Shok Reducer reduces the Cannondale SI cups down to work with a EC34 1-1/8" headset and will not work with a tapered fork because the lower Cannondale Cup is technically 1-9/16" although it is sometimes referred to as 1.5"

I ordered this for a friend to replace his no longer serviceable Headshok. The adapter still uses the original Headshok cups, but the bearings come out very easily with no special tools, then these slip in allowing a conventional 1-1/8" headset to be pressed in. At first I was concerned with so many joints and the added height, but he's had nary a whimper in weeks of hard riding.
