BaGearA Posted January 28, 2020 Posted January 28, 2020 According to this guy, XX1 & XO1 chains get you the same mileage, so that means XO1 is the best bang for your buck.Also according to this guy, XX1 & XO1 rob you of about 3watts because of the extra coatings leading to super tight tolerances, so probably not the best for race day if you're super competitive.https://cyclingtips.com/2019/12/the-best-bicycle-chain-durability-and-efficiency-tested/3 watts ? over say 3hrs ? i think you'd be better off just riding around more pebbles Wayne pudding Mol 1
Christofison Posted January 28, 2020 Posted January 28, 2020 imagine the size of that thing behind a 50T sprocket though haha. will get close to a 24" wheel lol. I already cant get over the dinner plates on back wheels of modern mtb's. it Just looks wrong this is where we are heading :No, this is where we are heading...https://www.pinkbike.com/news/shimano-gearbox-in-the-works-files-patents-on-hybrid-roller-chain-sequential-shifting-transmission.htmlhttps://www.bikeradar.com/news/shimano-gearbox/
W@nted Posted January 28, 2020 Posted January 28, 2020 (edited) got about 6500k on xx1 chain, replacing now. wont go any other route...What chain lube do you use? I tried wend wax for about 500km on my new gx eagle chain. Already approaching the 0.5 wear mark, so not impressed at all! GX eagle Cassette also done after 3200km. I am going to ride this chain and cassette moertoe and then put xx1 on. Edited January 28, 2020 by W@nted
Hamstring Posted January 28, 2020 Posted January 28, 2020 i have an GX cassette and xx1 gold chain that i put on sum time in 2018 after Epic but lets go just with 2019 7500km and to date 2020 734km. Wayne pudding Mol 1

W@nted Posted January 28, 2020 Posted January 28, 2020 squirt dry lube i do wash/clean drivetrain oftenThanks, I have moved back to smoove and regular chain cleaning.

manbearpig Posted January 28, 2020 Posted January 28, 2020 (edited) 2 x Chains rotated on one cassette and chain ring lasted about 8000km. The chain did start to jump off the chain ring on rocky descents though. Talking GX Eagle. Edited January 28, 2020 by manbearpig
love2fly Posted January 28, 2020 Posted January 28, 2020 GX Chain : 1000km TAYA Gold 12s : 300km XO1: 1800km XX1 : 500km and still no sign of wear. When fitted the Park Tool Chain checker wouldn't fit at 0.0% wear and it still doesn't. The XO1 eagle cassette has seen all these chains and all chaines were replaced at 0.5% wear. At this point the wear is visible because the chain starts to lift off the 42T and 50T sprockets about half way around the chain wrap. lesson: buy an XX1 chain. I don't know anyone who is using one that has replaced it yet. I even have on on my road bike nowCould not agree more. Have now done double the distance I got with GX chain and no wear, plus I weigh 110 kg so the thing works hard! Plus the gold looks lekker!
babse Posted January 28, 2020 Posted January 28, 2020 chain rotations...nah not for me thanks! DieselnDust 1

I'd be more circumspect when taking wattage claims with anything more than a pinch of salt.9. 0006 difference in friction coefficient x 0watts is still zero
Jehosefat Posted January 28, 2020 Posted January 28, 2020 I'd be more circumspect when taking wattage claims with anything more than a pinch of salt.9. 0006 difference in friction coefficient x 0watts is still zeroI'm not sure what your point is? The link pointed to actual tested wattage losses in a given set of conditions by a relatively independent team for a bunch of different chains. It'a not a theoretical friction coefficients calculation. (Obviously the testers are not completely independent because they do sell their own chains and chain treatments but as far as a Shimano vs SRAM comparison goes they seem to be reasonably independent)

The sample size is too small. They do not establish a norm so what is the baseline? Sounds sciencey but straight away I can see their BS
MrJacques Posted January 28, 2020 Posted January 28, 2020 https://www.vitalmtb.com/forums/The-Hub,2/SRAM-Eagle-chain-longevity-is-impressive,9934 Older post and no doubt the Sram chains have great durability, but if the chain checker doesn't fit when it's new, then doesn't it have an advantage to start with?

Sounds sciencey but straight away I can see their BS I didn't see any discussion of sample size there (unless I missed it). What I got was that there were 31 different models of chains and each individual chain was tested twice, no mention of how many chains of each model were tested. (And even then that section was specific to the durability testing rather than the efficiency testing). I'm not sure why you need a baseline when you are doing a relative comparison. If a system loses 5w between crank and rear hub and the exact same system with a different chain loses 10w, where else can the additional 5w come from?
