    SIR rear dropout crack issue resolved?

    Cautiously considering buying a 2012 SIR. I had a 2009 MCR that cracked at the rear dropout. At least 6 other riders in my area had their frame crack in the exact same spot, and there are threads showing the exact same crack: Broke my Niner... then fixed it!. In other words, this is not a one-off thing.

    Did Niner address this with later models or would I be set up to eventually have the same problem?

    Thanks in advance.

    The new Sir9 has 142x12 Through axle & not an open drop out, so mush stronger there.

    I think he is asking about the Standard Headtube frame. I know Niner doesn't, but most of the vendors label them as 2012 and the redesign as 2013.

    With that said, I'm not any help on this topic, but would be interested to hear input since I am building a "2012" Sir 9 right now.

    That's right -- 2013s have the 142x12 Maxle, 2012s have the 135x9 QR dropout.

    The dropout was changed as soon as they reallized there was a problem. The area the hanger bolts on was made a bit thicker and it no longer had cracking issues.
