Chain's I usually buy off ebay, the RK XSO 110L on the bike now was $70 shipped I think. I'll probably replace it in spring just because of all the salt and shit this winter, probably close to 12k on it and its not really wearing at all, same with the sprockets.
Never run out of ideas, traction, and real estate at the same time...
