Might be in the same boat with a Campy Record wheelset w/Suntour Winner Pro. Tried to remove using a 2-prong remover and broke one of the ridges on the freewheel. Soaking in penetrating oil currently, and will have a go with a 4-prong remover (once I get one). Would like to save the freewheel if possible, but need to get it off and definitely save the wheels/hubs over the freewheel.
