    SIR9 questions

    I'm 6'3 with 34" inseam - Currently riding a 21" Dambala with 120mm stem & FuBars, 180mm XT cranks, and a setback seatpost.

    Would I be better off with the Large or X-Large SIR9 frame?

    Anybody encounter foot strike or ground clearance issues with 180mm cranks on the SIR9?

    Thanks for your help!

    I would guess XL.

    I'm 6ft, 32" inseam and have been riding a Large with 90mm stem. They do have longer top tubes though, so you might want to see if you can get a test ride on a Large with a longer stem to see how it feels.

    i am 6' 4" on a XL MCR with 120mm stem.

    you are a little shorter than i am but i am a long ways away from a L. i would put you on a XL without question unless your arms and/or torso are quite short.

    I'm 6'1, 175 lbs and I ride a large MCR 9 if that helps.

    I'd say you need an XL.
