Gear freaking in progress
The old three-bolt cottered cranksets found on lower-end Raleigh "ten-speeds" like the Record and Grand Prix used what, a 116 BCD? Most bikes came with a 52-40 rings or thereabouts, as I recall. Does anyone know what the smallest available ring would have been? I'm guessing at least a 38, and maybe a 36. Can anyone suggest a source for a ring of that size?
