Holy war: Chains and lubricant the ongoing story of the chain eating Sirrus

Since the original post I've engaged in an experiment. Ever wonder how good the lubricant found on SRAM chains is? Sheldon Brown extolled the virtues of this waxy grease called Gleitmo. I always kind of doubted what he was saying about it and like most would remove it after couple hundred miles.

On my last sprocket and chain change I left the chain lube alone. A lot of it had to do in part with just not having the time to tear everything down and go through the whole clean ritual that I would go through.

In the ever accumulating miles I didn't hear any squeaks or anything indicating that it needed lubrication so I just kept rolling. As of today's date I have over 800 miles on this drivetrain. Chain wear seems to be a whisker over .5 but not quite .75. I'm going to continue to roll with it to see how far I can go before the chain hits .75. I have a whole new drivetrain at the ready so I'm not concerned about wearing anything out (because I was expecting to replace everything anyway)

Factory chain lube seems to vary. First few KMC chains (Z33, Z50, Z72) I used to replace my worn Shimano chains, I just wiped down the outside plates and ran the KMC chains as-is to see how long they'd go without maintenance. Both ran for a few months with nothing more than occasionally wiping down the outside. When I finally relubed I just sprayed on Tri-Flow.

But the KMC Z72 I put on my road bike in June felt like it was packed in light grease rather than oil. The chain ran only a week or two before it began squeaking. Something was different. Maybe they were using rust inhibiting grease similar to RIG, which isn't noted for being a great lubricant.

Gave me an excuse to try wax, which I'd been curious about for awhile. Stripped the chain grease, dipping in hot paraffin. It's going on nearly a month and a few hundred miles, no problems. Very quiet and smooth. We'll see how it goes over the long run.

It seems like you are using some kind of chain checker, which have a reputation for inaccuracy. I would suggest that you use a steel rule to measure your chain instead, if you want to collect meaningful data.

If there's visible wear at 800 miles, either the measurement is wrong, the whole drivetrain is knackered, or it's a on a San Francisco cargo bike full of automotive batteries.
