i fitted a new SRAM PC951 Chain on my GT Avalanche tonight. The bike has only done 40 miles, but I am paranoid about the chain snapping as I am a big guy and wanted to fit a strong chain. The bike originally had a kMc HC-53 and has Shimano hg30 Cassette and An FSA dynadrive Chainset.

The New chain is so noisy, it sounds like its almost grinding, like a chump I also split the old chain 1 link behind the quicklink, as I couldnt figure out how do remove it until I got it off the bike. . . .

so my Qs are, why is the new chain so noisy and will it be OK to fit the old chain back on with a link missing?

arrrggghhhhh! :roll:
My biggest fear is that should I crash, burn and die, my Wife would sell my stuff based upon what I told her I paid for it.

    Sounds like you have not fitted it correctly.

    Hi cheers, but I dont see how it can be fitted incorrectly, its not fouling anything that I can see, its just much much louder then the old chain, I measured the same lenght etc somthat is all the same. :cry:

    Inspect the routing in the rear mech.

    What an absolute Donkey. spot on nicklouse, I cant believe i missed that, the chain was the wrong side of the guide on the arm. I am blaming it on trying to fit a chain late at night on a cold garage floor on my knees. . . .v. :oops:

    I wouldnt mind but I'm a bloomin Engineer. . . .Doh :roll:

    Very common.....

    Good practice for getting it right when on your hands and knees by the side of a trail working by just the light from another riders lighting though........me last Wednesday!

    Sometimes argue on trails where one or more will insist it should be routed the wrong way, rubbing against the mech guide. I can see how you think it should go that way. I did that myself early on until it was pointed out to me it was wrong! Do it the right way, and suddenly that noise is gone! D'oh!

    I re-greased the jockey wheels on the rear mech in an ignorant effort to reduce the grinding noise, before realising the same mistake. Doh! :D
    If at first you don't succeed, spend some more money on kit!

    Just take the saddle off and use an old fashioned steel post as support!
