a picture is worth 1000 words, Shimano SG off 1991 marin
so questions, totally knackered or a little left ? why is wear so irregular ? is there an easy check for the chain (I don't have a specific chain wear tool) and this is off 7 speed and all the replacements I've seen are for 8/9 speed where I assume that the ring is slightly thinner to accomodate the narrower chain and hence less metal so wears quicker ? has anyone seen a good place for replacements ?
cheers,
