Whats a good hardy chain to get?
thanksDepends on what you mean by best.
The better quality the chain is the longer both it and your sprockets will last.
Of course, if you look after it well you can get very decent life from a lesser chain. I've only used ERV2 and ERV3 in the past ten years so I can't really comment on any others.
I think the stock chain is their 530VM?
It'll be stamped on the chain links.
