    Problems fitting an XO crankset to my 950 Element .

    For my 2012 950 Element 29'r , I just got an XO 2x10 crankset to replace the stock X9 unit .
    The big ring on the XO is a 42 while the X9's is a 38 .
    The XO's 42 is touching the front derailleur cage and wont
    fully insert into the BB .
    Do I need a different derailleur or just a smaller big ring .
    The XO's and X9's sprockets are not interchangeable either .

    SRAM has specific FD's for every chainring combo(26/39 and 28/42). They also have specific top and bottom pull FD's in the same direct mount version. It makes ordering a coffee at Starbucks a simple process by comparison.

    And they have a horribly complicated chart if you are changing between SRAM cranks.

    Flow Chart Maddness LOL
    So can I make this 42/28 crank work in place of
    the 38/24 unit ?
    If my derailleur was a clamp on , I would just raise
    it and it would fit but its a direct mount .

    Yes, you would need the SRAM S3 low direct mount FD for the 42/28 crankset. And you'd have to make sure you got the bottom pull version.
