    Busted rear derailer, 1st run!

    Any one else every have a brand new Saint rear derailer break within the 1st 5 minutes of actual ridding (excluding the ride around the block test ride),Didn't hit any rocks, crash or snag any sticks, typical WTF moment. Wasn't exactly JRA, hit a few jumps and drops a typical DH run, nothing too techy.

    No. I've had a Saint for over a year on my DH bike.

    Weakest part of the current bike for sure. Chain to short?

    No chain was ok, Either MFG defect or maybe was because I was running a short cage with a lage sized XC type cassette.

    yeah? hasn't on mine, i'm at 2+ years on the same der, its pretty scratched and fycked looking, but it still shifts perfectly. I'm not real easy on gear either.

    Sounds like you hit an off line. I guess that edge of being semi out of control and wrecking yourself or the bicycle is part of what makes mountain biking fun, and every once in awhile you'll go over the line.

    If your bike has significant chain growth when the suspension is compressed and you're running a short cage with a large cassette and a too short chain then yes, that could be the problem.

    Some useful information in this thread.

    I've been running a short cage with large cassette for years on my old bike with no problems. Guess my luck ran out.

    Bummer dude.

    Get a smaller cluster in the back and get another Saint. You'll be sound as a pound.

    the others pretty much hit it on the head.

    just hit your drops/jumps in a smaller cog gear.

    i run a 11-32t cassette since we gotta climb to ride out here. i just make sure to jump or hit drops in an appropriate gear.

    There's the outside chance that something like a stick got caught in your wheel, ripped your drlr off, and by the time you stopped to look it was gone, but...

    most likely your chain is too short for your combination of bike and cassette.

    Best way to know the right length.
    1. Remove the spring from your shock and reinstall the shock.
    2. Fully compress the suspension and tie it in place with a old toe clip strap. Strapping the rear wheel to the seat tube is usually easiest.
    3. Shift the rear drlr into the biggest gear.
    4. Wrap the chain through the full system including over the biggest cassette gear and through the drlr.
    5. Your drlr should be pulled forward, but still have a bit of slack.

    It's really easy to underestimate how much extra chain a DH bike requires. 8"+ of travel makes for a lot of chain growth at full compression.
    Can't keep track anymore - Giant, Santa Cruz, Pivot, Yeti, Norco, Salsa, Intense - if it rolls on dirt I like it :thumbsup:
