Chain replacement 3 speed

[BarbelMaster]

Hi,
I'm currently restoring an old 3 speed Raleigh chiltern and i have been thinking about replacing the rusty chain, iv'e read somewhere about bad cassettes but as this is a sturmey archer hub will it be okay to fit a new chain? or would it cause any complications?

Thanks

Harry.

If your chain is warn or rusty you should replace it, just make sure you use the same type of chain.

There is only one rear cog. This or the front chain ring might be worn. Did you measure the chain for wear?
