I see the clear winner was made by the factory the test was done in, hmmm.

What did you expect?

Another test done by someone else. Connex came up on top.

From that article-

Kerin's durability testing isn't the first in the space, and not long ago Wippermann Connex conducted its own such test to find the most durable chain. Some of those results line up with what Kerin found, but there are a number of obvious discrepancies (especially related to KMC and SRAM chains).

....

If the durability of SRAM's 11-speed XX1 chain was impressive, then the results of SRAM's high-end Eagle chains are simply mind-blowing. The top-tier X01 and XX1 Eagle chains both beat Kerin's 5,000 km test and only recorded 70% of the allowed elongation wear at the time of doing so. Extrapolated out, these chains would likely have hit 7,000 km with the terrible control chain lube. They're so durable, in fact, that they had started to wear through the cogs from pure abrasion before measuring as worn. Keep in mind that the control lubricant was intentionally abrasive, and so you can expect great life from your SRAM Eagle drivetrain if you keep it clean.

Sram xx1 is tops.

last. Why does the data show the sram xx1 chain lasting a very short time if its so good?

Different testing and/or measuring methods. I mean, if you design your chain to perform well on your particular testing apparatus with your particular measurement methods, of course it makes sense that if someone uses a different method to test and/or measure wear, then your chain might not perform quite as well.

Also, as shown here, Connex chains appear to be just a touch short to begin with, so they start wearing at a different point.

i thought jb welds quotes were from the article. They are from another test that i perused earlier. So sram chain life is not great in this test.

fwiw. I get about two months and 600km from my pc-x1 chains. But im dropping 500-1000w of load into them during interval training. (260lbs)

¨¨ And perhaps the biggest takeaway from all of this testing is that no matter how durable a chain is, the lubricant you use will play the most critical role in drivetrain durability. Kerin toasted an endless number of chainrings and cassettes in his testing, and basically, any chain that lasted over 2,500 km ripped through the cassette and chainrings through nothing more than abrasion from the gritty lubricant.

As always, run a good lube and keep your drivetrain clean – that’s the real trick to getting the most value and performance from your drivetrain components.¨¨

If the test is apples to apples then the differences between wear is consistent and fair to everyone. So sram high end to low end chain is telling.
