I don’t want to spoil this vid, but a lot of the video is spent talking about other-than-SRAM chain compatibility with SRAM drive trains.
All speed factors quoted for cleaned & lubed chains (not factory grease)
($$$$)SRAM XXSL → Speed factor comparable to Axis Road Red, not as good as Campy, Shimano Ultegra, Shimano Dura Ace
($$$)SRAM XX → Speedfactor same as XXSL
($$)SRAM XO → Speed factor better than XXSL, XX. Same as Ultegra/Dura Ace
Haha I’m so grateful to him for all he does, but I think he’s the only youtuber that has ever made me consider starting my own youtube channel. It would literally just be 5 minute summaries of his videos, released a few days after each of his. I’d aim to be to him what Lanterne Rouge is to the full broadcast of a world tour race
Graph summary: Campagnolo or YBN chains are the fastest!
I watched some of the video.
Conclusion for an SRAM rider: don’t use a different chain because the AXS system sprockets are designed to fit with the flat top chain’s larger rollers. A Dura Ace or other regular chain would see the Sram sprockets like worn out sprockets and you might have skipping.
The more expensive Sram chain was the fastest Sram chain.
And, don’t ride on factory lube if you care about watts. Properly lubed/waxed, the fastest Sram chain was as fast as Dura Ace / Ultegra.
