Checking chain wear?

Righto, I've just got myself one of the Park Tools Chain wear indicators (CC3) and understand that you just put it on the chain to see if it fits or doesn't to determine if you need to change your chain.

One thing that isn't clear is what gear should you be in when you do this? Or doesn't it matter? It's looking like my chain needs replacing anyway - but just wanted to check for my next chain. Thanks!

    It doesnt matter what gear but you should press lightly on the peddle to ensure you take up any slack in the chain and hook the concave end of the gauge in a link on the top run of the chain. If the other end of the gauge also hooks in then the chain is *****ed.

    Thanks Careful, that's exactly the sort of tip I was looking for. My chain failed the test, so I've ordered a new one and won't ride the bike till it arrives as I don't want to damage the cassette anymore than I may have already. From a clean and inspection - I think it looks ok.

    Thanks again.

    I have found the park tools to be pretty conservative. Changing the chain right on the 0.75 mark isnt always necessary, more likely better closer to the 1% mark.

    Thanks for your message. My chain comfortably failed the 1% test too but I'll note your comments for the next one. My Aussie mate in Melbourne reckons I'm fine to keep riding the current chain till my new chain tool arrives - so I'll probably do that. I had been worried about damaging the cassette.
