Kmc x10sl – snapped!
Nope, well not in my experience. Every KMC chain I’ve had has snap regularly, multiple times per ride sometimes. The frequency of chain snapping greatly reduced when I switched to SRAM chains, and is now zero, so far, since I’ve gone 1×10. I buy the cheap SRAM 10 spd chains and replace when the chain checker tells me to – about 2 to 3 times a year. I could probably stretch that out a bit if I did more frequent and better chain maintenance. I basically do nothing bar a quick wipe down and spray of 3 in 1 before every ride.Posted 3 years ago
3 week and 50 mile old x10 sl has just snapped on me when shifting rings on the front.
I was climbing so it was under load and when I shifted from the middle to granny on the front, one of the outer links has snapped and bent a couple of others at the same time.
Question is, was I just unlucky? Was shifting under load too much to ask of it? I’m assuming the lightened outer links just aren’t up to the job.Posted 3 years ago
Thought on going for a regular x10 or just a good old xt?JamieMember
i’ve never had a KMC chain snap, on the MTB, CX or road bike, but then i try not to change gear under load
The last kmc I used snapped twice under non shifting load. I’ve snapped shim/sram before. I’m no powerhouse and mindful about gear changing.

Never had issues with KMC, but then I’d also not bother with the SL version. Buy cheap and replace often is my advice with chains.
Have snapped 3 chains in almost 20 years of riding. 1 Shimano, 1 SRAM and 1 Wippermann (which was almost new, and I repaired it twice and it snapped again twice!). Never a KMC.
KMC make a huge amount of chains for both Shimano and SRAM (just like Giant make bikes for Trek and numerous other makes), so I’d certainly not write them off. There’s over a hundred links in your average bike chain, each an opportunity for failure. When you consider how many chains KMC will sell, if one chain in 1000 snaps prematurely, that’s 1 in 100,000 opportunities, which is pretty bloody good!
Changing chainrings under load though… Can’t really blame the chain for that one I’m afraid!Posted 3 years agoesher shoreMember
before putting your new XTR chain on your bike, have a good look at the transmission specifically the chainrings and cassette and make sure you don’t have any damage to teeth or burrs that caused the KMC to open up and fail
seen this too many times…
KMC aren’t known for snapping without an external issue like poor fitting (using a chain tool with a damaged pin) or damage somewhere in the drivetrain
most modern chains will withstand abuse without issue including bad shifting under loadPosted 3 years ago
Was a new XT cassette (11-36) that went on at the same time. The ring (24/32) aren’t new but I didnt notice anything too bad on them wear wise.
Will give them a good check over though. I did want to switch to a 24/34 or 26/36 anyway, so new ones might not hurt.Posted 3 years agocolournoiseSubscriber
Snapped three KMC chains in the last four months or so having not snapped any chains in the previous four years. Single ring up front. All three have gone putting in a power pedal on short techie climbs. All were fairly new at the time they went and running on newish cassettes.
Worth trying SRAM again (what I was running before), or are they really just rebadged KMC?Posted 3 years ago
