JR.1.78 T
Those JR initials say it all. This is a frame built for Jan Raas which he used at the 1978 SKOL 6 day in London. He was riding with Gerrie Knetemann, who was the current world champion and was wearing the World Champion jersey. As they were teamed, Jan also wore the World Champion shirt. He went on to win the title himself in 1979.
