Tom and the Supersport

This is a shot of Tom and Jim Clark doing a chain repair on the Supersport while on a trip. You will note the rear wheel on the bike, its a cast spoke wheel. It's been argued that AEE was the first to produce these for the chopper aftermarket. As I understand it they did 50 wheels on the first run but I have no info beyond that. Interesting as at that time cast wheels were not on production bikes.
