This is really neat Philippe Cross bike. It was built for and raced by Steve Larson who was a great pro racer. I don’t know if it’s true but I was told that only 4 of these were made. It has a curved seat tube to allow a really short chain-stay length. The best I can tell this is about a 1985 bike. The person that picked out the setup on this bike really knew what they were doing and it really shows a professional and knowledgeable cyclocross build for it’s day.
