    GT size their frames, or they used to at least centre of botom bracket to centre of top tube.
    My frame is a 14.5" but would be a 16" or small by "Normal standards"
    hope it helps

    Ok, so if my size is small, what would that be as compared to a brand like Giant?

    Depends on the model whether it is road, Mtn., or hybrid. Look at the decal on the frame for one. Then pull out a tape and measure it, or go to the Giant web site and see what they say.
    Bike manufacturera vart in how they measure sizes. Some like KHS, Kona, and Iron Horse on the upper end MTB measure form center to top of seat tube. GT measured from center to center. It goes on and on.

    Why do you size MTBs by their height. These days they all have standover clearance to spare. Sus versions may have variable height, some bikes dont even have seat tubes, and those that do, the design clearance may vary between models.

    Surely you should size them by the length, horizontally from seat tube/seatpost to head tube.

    Michael,
    The GT Avalanche 1.0 is a hardtail. Yes suspension models are sized differently. However I do not know at this time any manufacturer who sizes the bikes from seatube to headtube. Also given the fact there are those who may not be symetrically built "normal" this way of sizing will not neccesarilly work.

    I measured my frame size. It's small, and when I measured from the bottom of the frame to the top of it( where the saddle pole quick release is), it's 16.5", so I guess it's just right for me.
