I was able to purchase this track bike from a German collector. It is a brand new Chris Chance Pista bike, with Campy Record Pista parts. Never ridden since it was built in 1984. Stem and bars are Cinelli, as is the Seat. The rims are Nisi "for professional use only". It has a silver plated head badge and two other badges. One with a signature and one with the text "34-84, Bi-Ex 50". Not sure what it means, but from what I have been told Chris made this bike for a friend.
