>>1959891Should be fine with good cleaning, scrub it with a brush too. So many bike from the 80's that are still running their original chains lol.
Only thing to consider is the wear on the chain itself, which is checked with picrel (chain wear tool). If your chain is worn, it'll wear on the cassette and front chain rings faster, which will be more things to replace. But if you were gonna replace it all anyways down the line, I'm sure you can just use it all as is.
