do aftermarket chains do anything special
when i bough my bike the previous owner had given me two slightly used aftermarket chains. he said an O chain and then some other type. he also said that the current one has the Master chain link or something. he said it was something needed to put new ones on.
i could be mistaken and false on what he said. but is there a point to put one of the more flashy looking chains on it? or just keep the stock one on?
