Can anyone recommend a supplier of race quality heavy duty primary chains please?
Member Ricky Racer, he's Classic Cycle City in the USA, he sells them, if you are in Europe try member Nippon, he's Classic city in Germany, you've also got CycleX in the USA they have a similar Heavy duty chain but with small holes in the rollers for a supposed better lubrication, I have the original ones from Classic Cycle city {without those holes} and don't see any need for the ones with the holes...
