RC jr. Was on facebook looking for a source of double chain. It seems to be out of production these days. I offered my old one for display but it's too short and obviously not up to snuff for a twin or triple.
I was surprised when I measured mine it's more like a 520 than 530. About 1/4" between the plates, the 530 is closer to 3/8", does anyone have old stock or a source?
My rear sprocket is apparently magnesuim, it's pretty eaten up from corrosion or I might try to install it on something.
