That KMC X8.99 looks good. The mushroom rivets with dimpled ends should be more precise and secure than the lower priced KMC chains with plain rivets and peened ends.

If I'd noticed it earlier I'd have used that on my errand and foul weather bike. I just put on a new KMC Z33 chain and Missing Link II. I actually had to splice together a pair of Z33 chains to make the 122 link chain needed for my errand bike -- it has a long wheelbase and chain stay so the standard 116 link chain isn't long enough.

Get a good chain tool with adjustable anvil -- it should work with any bike and chain you ever buy. There are several on Amazon from $10-$15. Venzo includes a good shop grade chain tool with their tool kit but I don't see it sold separately. There are other similar models.

And KMC has good tutorials. There are several good video tutorials on YouTube as well.

Incidentally, don't be in a big hurry to over-clean the KMC chain and strip out the original lube. Before I put a new KMC Z51 chain on my mountain bike in September I wiped the outside with a shop rag dampened with mineral spirits -- just enough to remove the excess without stripping the oil completely, so it wouldn't attract too much grit and still wouldn't rust. So far, so good. I've ridden hundreds of miles on gravel and gritty rural asphalt and chip seal, some light rain, and have only wiped down the outside of the chain with a dry shop rag. I haven't used a chain cleaning tool with solvent or needed to re-lube the chain. It still runs almost as quiet as when new. I'll wait until it's really grungy from riding in rain or mud before doing a thorough clean, which is easier to do with the chain off the bike in a container of solvent, then re-lubing and wiping down.
