    KMC X10.93 10 Speed Chain
    Sram chain didn't have as much longevity in published tests in a German mag.

    I haven't broken it. And it has solid plates. But what are you doing when your chains break? Are you certain you haven't cut them too short? I shift under some but not full pedaling tension when climbing. Technique impacts chain breakage.

    The 1st time I broke the chain I was pedalling hard downhill, while the 2nd time I broke the chain which is 2 days ago I was pedalling uphill. I end up walking 15km to get back to my car.

    The lbs are the one who installed the chain, but this time I will do it myself.

    Kind a hard for a shop to screw up a KMC chain install considering they use master links. The only chains I have seen fail due to installation error are Shimano chains when the Shimano pins are used instead of a master link.

    One chain breaking, I'd chalk it up to crap happens. 2 chains breaking in a short time period I'd suspect rider technique is a possible cause for chain breakage.

    the chains may have been too short.

    That's a possibility for sure, but I have my doubts since it happened with him going downhill as well.

    Who knows for sure.

    The sl version is not stronger than the lower priced ones, just lighter and better coating, hence more expensive

    I like my SRAM chains. I would suggest getting some Quick-links/Power Chain connectors and a Master Link plier and throw it in your backpack. So you can fix your chain on the trail instead of walking 15km back to your car.

    I'd suggest giving a Shimano chain a try.

    He said he was pedaling hard downhill, meaning the chain was under tension. Suspension can compress and cause chain growth (depending on suspension design) in either case, putting large peak loads on the chain.
    I weigh over 200 lbs and have ridden kmc sl chains for at least the last 5 years, including on my SS, and never broken one. I even have one with two missing links in it.
    Doesn't mean it wasn't the chain, just sayin.

    There's a chain test chart floating around that i couldn't quite find, but here's a similar one:

    http://www.connexchain.com/data-live...ier_080306.pdf

    Naturally the brand doing the testing came out on top, go figure... The one i saw also had KMC chains in the mix, and they were solidly in the middle. SRAM was at the way bottom and Shimano didn't do much better.

    So i run the KMC 10.93--$22 shipped on Amazon, they seem to last a long time, and they shift great.
