I ride a 1998 cannondale f400. I came across another one on craigslist that is an f400 from about the same era with the same paint scheme except it has a v type frame. I looked all over and couldn't find any specs about the v frame bike on bikepedia or vintagecannondale. An f400 killer-v is mentioned in a few forums but I can't find any official reference. Can anyone help shed some light on this for me? I attached a picture of the f400 killer V.
