Brompton Stem expander bolt size?
Does anyone know the size and length of the expander bolt on the brompton stem? I'm at work at the moment and cannot find a replacement or size info online.
I have an idea for using a bmx hollow stem bolt to run dynamo wires up through the fork tube. But need to know if I can find a compatible bolt size and length.
