I've already adjusted the chain by standard method to the max so I'm guessing the chain itself has stretched out. And I've seen guides on removing links in it but they're done with a special tool by breaking off a particular (master?) link or something that is obviously different from the rest but I see no special link. Can I still do this or should I buy a new chain? I haven't used too much I don't think, at least enough to warrant a replacement so if possible I'd like to try to double the life of my chain. Any ideas? Thanks
