XTR M9000 with KMC X11SL chain?
« on: April 16, 2015, 06:11:06 PM »
Hey all, quick question. Upgrading the wife's bike from 10 speed XT to 11 speed XTR, and discovered that the KMC X11SL chain seems too narrow for the top jockey pulley on the XTR M9000 derailleur. Anyone else try this combo? I know I can go to an XTR chain, but I've run the KMC X**SL chains for a while now with great results, and they're damn light. Might try the slightly wider 10spd chain and see how that goes.

Sorry, I can't help you.  I had a KMC chain on my last 9-spd.  Seemed like a good chain for the money.

Thanks - measured things, and the pronounced teeth on the XTR pulley are 0.87-0.90 mm thick, with the inner plates of the X11SL chain measuring anywhere from 0.85 to 0.87mm wide. See the problem? I put a 10spd chain on her bike, and it's golden. I saw that the biggest cog is offset inboard to allow the wider range of gears, so that might be why a road 11 speed chain won't work. 10 speed chain was fine - she raced the bike in that setup today - and no problems.

Amusingly enough, the 11 speed chain fits the 1x10 drivetrain of my fat bike just fine, because the XT jockey pulleys have the more conventional low profile "teeth"... so I get a free weight-weenie upgrade on that bike! :D

Sorry for the hijack, but it is about XX1.

KMC mentions in their marketing, some racers using the X11 SL on XX1.

I tried but it didn't work well.
As soon as there was a climb, a "clic-clic-clic" noise was coming from the chainring(a SRAM 28T at that time),
The noise becoming stronger with the climb.

Anyone has tried it successfully on an XX1?

Cool to see Sabine Spitz listed, KMC must be a sponsor. Sabine is my wife's favorite racer. Stirneman was crazy strong in the XC Eliminator, really sorry to hear that they cut those for this year. They were fun to watch.

Thought I mentioned but I guess not - heard that the spacing on the MTB 11 speed cassettes is the same as 10 speed, and a buddy who works in the industry said he knows that the SRAM 11 speed road and MTB are incompatible, so that might be why. Could be the X11SL only works well on the narrower road 11 speed stuff.

So the question now is what I'm gonna do with four extra X11SL chains - I tend to stock up on wear items. :)

Absolute Black recommend the KMC X11 SL chain on their website.
KMC's message is somehow misleading by saying it works on XX1.

Thanks for the list, I now have a series of potential upgrades :)

Can't speak to XX1... yet, but I've got X1 on my bike and could never get the stock chain to run completely silent. Chain just started to show some wear, so I swapped it out for the X11SL and am happier with that. Amusingly, looking at the specs on my bike, the stock chain is listed as a KMC X11L.  ;D All along I thought it was a SRAM chain. Even funnier that swapping the X11L to an X11SL made things better. Must be the extra S that fixes all the things.  :D

Strange, I didn't have any issues with my XTR M9000 with the KMC X11SL chain. I was also using the one up 45 t cog without issues.

I can confirm no problems as well, M9000 with X11SL going on together flawlessly.

I've ride about 75km with a KMC X110SL chain when it broke. It broke after a corner when started pedaling, flat surface. So, for me no SL chain anymore.

I broke one once, the only time I didn't lube before riding.
Not sure why but I prefer the shifting(crisper?) of the KMC 11 SL than the XX1 and X1 I tried.
