hello, this post may be very old. i am too lazy to read through the 3rd page.

i have broken 3, yes THREE KMC chains. one was on my old IRO track set up, other two were on my tsunami track set up. both set ups were track frames, with track wheelsets, the spindle length was correct, the 1st crank was an IRO, crank on tsunami is sugino 75 with zen ring. the chainline was perfect. these chains were all broken running 47x14, sometimes 47x15 in hilly syracuse, ny. where i've been for the last few years. i am moving back to manhattan and don't want to eat **** after a link fails and wraps around and locks the rear wheel. anyone who has brooken a chain while starting a sprint up hill knows that it's pretty scary with traffic around. and it sucks when the chain goes through your spokes and a chainstay, so that you bend a few spokes in addition to twisting the chain.

i'll admit, in one case i forgot i had a half link on there which is most likely the reason it failed, but in the other two cases, i had a straight chainline and good tension and well cared for, lubed and cleaned frequently. all links were smooth (i know how to use a chain tool). in all cases i was not using a master link. maybe it was the salt they throw down after a snowfall, although i dunno if those chains contain any allu. does salt **** steel? i ride brakeless and have been for many year

i might just make a new post, but is there anyone on here that has broken multiple KMC or similar average grade chains, has upgraded to something absurd like the super toughness or DID and noticed a significant difference? once you get going any chain will do just fine. but it is the stops and starts that have ***** my kmc's. should i buy the $60 toughness or just buy a new KMC every 4months?

f-ucking fixed gear. this s-hits a ****-ing disease. mother f-uckers
