    I lay down too much power

    I snapped my new Dura-Ace chain on the final hill climb of today's 86 km RR.

    That is all.

    given a chain is rated for 2866 lbs of force I think you improperly installed the chain or the rd,

    That is all

    That's only about 4800 watts, though, at a 50 RPM hillclimb. I don't know what the OP is bragging about; I thought everyone could put out that kind of power.
    Reacting is mind candy; it requires no thought. Thinking is tedious.

    I snapped a dura ace chain at the end of a ride a while ago. I think it had to do with it not being installed properly. One LBS put it on, I took a trip somewhere, and another LBS put a SRAM chain on. The second place said that if you don't do the right thing with a certain gizmo (link pin) then you can end up with problems.

    Sounds like a case of massive Guads, have you measured them?

    I snapped one the other week. I seriously thought I was the strongest eprson alive when I did this.
    I was on the flats, on a recovery ride after a race, and I stepped a little hard on the pedals, and the Super-Duper pin that it comes with snapped right in the middle. Granted, the chain had 3,500-4,000 miles on it, but it shouldn't have broken like that. One half of the pin was still inside of the chain.
    I'd like to tihnk I'm that powerful.

    It was a Dura-ace chain that failed me during a full on sprint last June and put me hard on the ground. My fault im sure. I used a park tool to install and remove links instead of the recommended shimano tool. Seemed ok for a while...

    Still, i'm sticking with Park tool compatible SRAM chains with masterlinks from now on. I've been using SRAM and Sachs for eons with out fail. I shoulda never bought the D/A chain.

    7801 chains have a slightly different diameter pin to them and require the proper chain tool. Using an older 9 speed specific chain tool means you'll create a weak spot. Also, if you don't get the 3 clicks when pushing the chain pin through during the install, you're in for something bad (that's how you rip your rear derailler off the bike), and also make sure to install the chain pin sans pressure. Its a pain in the ass and they don't really explain it well, but it does work quite well if done properly. For those that can't/won't 7801s still shift best on DA drive trains, just get a KMC super link.

    Park's works well for the HG chain. It's also better than using the $120 HG tool, though the tool is awesome.

    DuraAce chains are pure crap because they're made from low quality foreign carbon fiber.

    And here my LBS told me this steel chain was a Dura-ace.

    Man, I'm such a sucker.

    Well done. You need to yell out a big "YARRRRR!!!!!" right before you break your chain. Then when people see it sliding down the street and look up at you, you can just point to your guads. It's quite intimidating.

    If you're strong enough, you can just put on your rear brake and then lay into your pedals and snap any chain though your frame will flex to the drive side before that happens. If you have a cheap frame (under $5000), consider it toast.
