    Sram 971 snapped 3 times in one night.

    I have never had problems with sram chains, but I bougt a bike and it had a 971 chain. It was not beyond the srtretched point. A couple nights ago, the master link broke while riding. So, I put the chain back together and then the next night it broke in two other different places not close to the master link I put back in. Obviously, I'm replacing the chain. My firiend bought the same bike and it had the 971 with no problems. (They were demo bikes so they were sold as is.)

    So, is this just a chain from a bad batch?

    My question is, should I get the 951 or the nashbar brand chain. I have always used these, my theory being they may be heavier and have stronger pins. Is my theory flawed, or should I replace with the 971?

    I suspect either a bad chain or user error. If it was a demo bike who knows what happened to that chain before you got it. For example a jammed chain could have bent the chain.

    I have used 971s for a few years and have never had a problem with durability.

    Replace with whatever you like. I like SRAM chains because they are easier for me to work with. Your results may vary.

    something is stressing the chain - look for a snaggletooth on your chain ring or something to damage the chain
    I also know I've lost a chain to a simple green soaking for a few days once before.
    I trust both SRAM and Shimano chains- SRAM usually last me a year while Shimano will last me 12 months.

    That may be the case. When the master link broke, I was going uphill. When the other two breaks happend, I was going from a start on a flat street.
