I just acquired this 1940’s model Paramount Racer, and although, I don’t know much about it, it does appear to have a special order geometry and in the team colors.
It’s unusual, in that the frame has a standard seat tube height, but with a very short top tube length.
The standard wheelbase for these models, was 40-1/2” axle to axle.
This one measures out at 38”
Because of the steep angle of the downtube, the fork has more rake than most track bikes of this type.
If a standard track fork had been used, the front wheel wouldn’t be able to clear the frame.
Someone’s personal preference?
It definitely seems to have been a custom order, maybe for a female rider, of a guy with a compact upper body?
Who knows?
I’ll add any additional information that I find out about it, in the future.
It looks like the team bikes that were used in the 48 London Olympics, so maybe a 48 model?
