I am a novice, but getting a crash course. Have done a bunch of reading in the last couple days. Your help would be appreciated.
Started riding my ~30 year old, 10sp, mountain bike in lieu of running till an injury healed. Bike manufacture unknown, as I stripped and painted it as a kid. Busted the chain and not certain what to do. Measured stretch of no more than 1/32” over 10”, so I would guess this chain is still GTG if I can put it back together “properly”. I believe this is the original chain on Shimano cogs and SunTour derailers. It is a bushing-type chain. Width of pins is 7.8mm. Width between inner links is 2.5mm. There are markings on some of the chain outer links, but not all: “W S”, “TAIWAN”, and “4-3” on a single link. There is a single “master link” on the chain already, one side only. LBS sold me a clip-type master link to repair this chain, but it is too wide for the rear derailer, if not the cog spacing.
Some posters indicated in threads I read these older chains suffer little weakening by reusing pins and links. Should I straighten the bent outer links and simply reassemble? Purchase a proper “master link”/PowerLink/Missing Link/etc? If so, not certain which one. Advice? Thanks.
