Yep, 130x15.
It isn't a Strayer track bike. It was build for a speed record.
José Meiffret went 204 kph (127 MPH) behind a gull-wing Mercedes-Benz 300SL on the German Autobahn in 1962.
The bike was 40lbs and had wooden rims to withstand the heat.
By the way, Meiffret was a Trappist monk. He said,
“In case of fatal accident, I beg of the spectators not to feel sorry for me. I am a poor man, an orphan since the age of eleven, and I have suffered much. Death holds no terror for me. This record attempt is my way of expressing myself. If the doctors can do no more for me, please bury me by the side of the road where I have fallen.”
The guy crashed once at close to 80 mph and the newspapers announced his death but he lived. That's when he decided to become a monk. I know several Trappist monks and spend a little time now and then at the monastery near me. Those guys are hard as nails.
