ChrisTrials2012 Posted July 20, 2012 Report Share Posted July 20, 2012 I snapped a KMC singlespeed chain in just over 2 hours today. It was brand new, with no split links. So I reset it by shortening it another link, and put it back on. it snapped in 5 minutes. The plates also appeared to seperate on the second snap. is it to do with chain tension, or was it simply not strong enough? Quote Link to comment Share on other sites More sharing options...
Jake. Posted July 20, 2012 Report Share Posted July 20, 2012 Maybe too much chain tension, maybe you didn't use the chain tool to put it back together right. Pics? Quote Link to comment Share on other sites More sharing options...
Sam Nichols Posted July 20, 2012 Report Share Posted July 20, 2012 Yeah, that definitely sounds like you're doing something wrong. Whack some pictures up, maybe connect up what you have left of the chain (off the bike) just so you can take a snap of where you have joined the chain up.

ChrisTrials2012 Posted July 21, 2012 Author Report Share Posted July 21, 2012 I think it was a case more of lack of tension plus static loading that made it die. I always use a tool for it, cause I find punches and a lump hammer are too fiddly. Also, the pins head may be deforming when i push them through using the chain tool, causing the plates to separate. I'll try and get a pic of it, but it won't be easy. Quote Link to comment Share on other sites More sharing options...

ChrisTrials2012 Posted July 22, 2012 Author Report Share Posted July 22, 2012 You're doing it wrong. You sir have won the internet. But it was infact the chain, as I got another, and I snapped a plate. Therefore the chains as a rule aren't strong enough. And I was gapping at the time which gave me a nice few scrapes and gashes, as I was thrown six foot on to my face. Quote Link to comment Share on other sites More sharing options...
ogre Posted July 22, 2012 Report Share Posted July 22, 2012 (edited) what condition is your chain tool? if it's worn/damaged etc then it won't join chains right and they're more likely to fail. no offense but are you familiar with joining up chains? you need to be prety analy about it in trials cause its not a forgiving game when it comes to chains...

ZeroMatt Posted July 22, 2012 Report Share Posted July 22, 2012 If its just separating check the chain line isn't too far out. Quote Link to comment Share on other sites More sharing options...
konstant Posted July 22, 2012 Report Share Posted July 22, 2012 It can happen. I've snapped a Z610 on its first outing, verified by Tarty to be not be due to faulty joining. Since then I've been running bigger chains without problems, though I've just put on a new 610, so I guess I'll see... Quote Link to comment Share on other sites More sharing options...
konstant Posted July 22, 2012 Report Share Posted July 22, 2012 On a side note I far prefer chains that come with a C-clip style joining link to the powerlink style link that came with my recent KMC branded Z610. The former should be no less strong than a normal link, plus is super easy to remove, even under tension. Quote Link to comment Share on other sites More sharing options...
ChrisTrials2012 Posted July 23, 2012 Author Report Share Posted July 23, 2012 Its the chain, as I load the drivetrain like a muthaf**ka, and the ones I had were simply rebranded 9 speeds by the looks of things. I just got a k710 kool and its holding up, so its all good in the end Quote Link to comment Share on other sites More sharing options...
