have to go much earlier than that. Klein had early production bikes in 1975, I test rode one. There was a Bicycling! Article in 1974 about his MIT project track bike. There apparently were other students with the same solutions.
‘the problem was 1973, an image in Competitive Cycling showed an oversized welded aluminum tubed bike and its unique construction was noted and attributed.
Lots of prior art.
