    Sizing for 29er

    I have a Question. If you ride a large size in 26" wheelbase, What would you ride in a 29er? Someone mentioned to me today that you should go down a size? I could not understand why? Any thoughts?

    Fit is fit. Not all "large" frames--26" or 29"--have the same fit spec. You need to look at the geometry and test ride.

    The trouble with common sense is it is no longer common

    If your large 26" fits you the way it should be, compare the standover and top tube length to the 29er frame you're looking at. Its usually one size smaller.

    Rode a Medium 26er FS. Ride a Large Niner EMD. Definitely agree with Shiggy

    Even within the same manufacturer, the geometry is different. ie, Redlie Monocog has a longer top tube vs a Redline Monocog Flight. 17" MC TT = 19" MCF TT

    Test ride if you can. I am going from a 17.5" Full Suspension 26" to a 19" HT 29er
    Enjoying the trails one pedal stroke at a time...

    I'm curious about this too. I'm going to be receiving a Tomac Flint 29er frame shortly and am getting parts for it as we speak. (still need a fork!) I'm 5'8" and ride a medium FS 26er. The smallest the Tomac comes in is a medium. I'm alittle worried it might be big. The stock spec is a 90mm stem, should I be looking for an even shorter stem?? Should I also make sure I have a straight seat post? (not set back) (by the way if anyone has a 90mm 31.8 stem let me know!!)

    My 19" Giant 26er was actually smaller overall than my new 18" Kona 29er.
