My dad emailed me this scan he made of a glass plate slide taken way back when.
It is thought that the bloke on the left it is my great-grandfather’s younger brother Alf. He was a gun cyclist in the area and the family still has a gold watch chain that he won in a local race. He was killed in a horse drawn vehicle accident before WW1
Check out the monster chainring and crazy fork rake
The cog is pretty big too, the gear isn’t stupidly high (for a racing bike)
Don’t forget they raced on dirt roads, more stable geometry was an advantage and that fork rake is matched to a very relaxed head angle.
Inch pitch chain is very stiff laterally (so won’t throw it) and tight chains slow you down.
