    Short Cage D on Spitfire

    Just got my new Spitfire frame. I normally run a short cage 10 speed rear D on my AM bikes. Anybody know if I am going to run into troubles with chain growth?

    Medium cage front derailleur is a much safer bet.

    I rode a short cage X9 on 1 x 9 setup 32T front 11-34 cassette and it did not work. I removed the shock, cycle the suspension and everything was looking ok but on the trails it failed. As soon as I pedaled when the suspension was compressed the derailleur hanger broke.

    I also tried a 1x9 setup with short cage Sram X.9 derailleur with 11-34 cassette and 32T front ring on my Spitfire when I first got it and it did not work. To have enough chain slack with the suspension fully compressed, there was not enough tension in the highest gear. Mid cage X.9 derailleur has been working perfectly though.

    I've been running 1x9 on my bike for about a year now, with a short cage derailleur with no problems. None of the issues already mentioned.

    What range cassette are you using?

    Yep, ran short cage 9 and 10 speeds, single ring setups, no troubles at all. Don't think it's any issue with a single ring, thoughlikely trouble with a two.

    I have been running a short cage X9 on my Spitty for 18months now—no issues at all! I currently run it with an 11–34t cassette and a 34t front chainring with guide. Anyone having 'not enough chain' probably set it up incorrectly and had exactly that—not enough chain—nothing to do with the short cage d. I run my chain as short as possible to help minimize chainslap.

    Running a 32F single and a 32 rear with a short with no problems. Just take the shock off and make sure you have enough chain when fully compressed. Just like what was said above .

    With an air shock you don't even need to remove it, just let all the air out and make sure you compress the bottom out elastomer fully.
