>>1093767>Are quick release links worth while?Yes, much better than fucking about with chain breakers (there are still times when you'll need one, but there are times when you just need to remove the chain without shortening it).
>What do I need to check when buying a new chain?Just match the speeds, that's pretty much it. Same goes for the quick links. Certain chain sizes will cover multiple speeds with older lower speed drivetrains, for example 6 and 7 speed use the same chain and I think 8 and 9 do too.
>Any suggested places to buy bike stuff online in Australia?Ebay, Amazon, Chain Reaction Cycles. As a Britfag I also use Tredz, Wiggle, and Planet X/On-One but can't be arsed to check if they deliver to Aus.
>Does anyone have any ways of getting pins back into a chain after it has come all the way out?Lay the chain flat on a sturdy surface (wood would be best), hold the pin with pliers (probably needlenose), line the pin up with the hole and give it a tap with a hammer to get it started. Good luck, if you can't manage it you'll probably be fine shortening the chain by a link (one inner and one outer) so you can try again not to drive the pin out too far.
