    frame sizing factors

    1) does height of the individual really matter that much?
    2) what other factors should one consider?
    3) the range seems narrow...not as critical as a MTB sizing. is this true? so what is actually changing? the wheelbase?

    i am 5'4" and was probably going to get a 20" frame...but what is so different than a 21" frame? would it hinder me in any way to have a 21"?

    Your frame should suit the type of riding you do and your size and style...



    Since your 5'4 i would get a 20.5" tt nothing bigger.

    if you got a frame that was too big, it would be harder to do things on your bike that you sould normally be easy on a bike that fits you (manual, jump). The 21"tt would be too long for you, I agree with kinetikbiker that 20.5" would be as long as you should go.

    The longer the frame is, the longer your wheelbase becomes, and the more stable the bike gets (to a point). Shorter riderds have less leverage against a longer frame and taller riders sit higher between a smaller wheelbase on a short frame.

    Other factors to consider are things like HT angle and rear triangle length. Like a mountain bike, road bike, anything, head tube angle translates directly into how quick or stable the steering is. And a short rear triangle puts your weight further over the rear tire...making steering and front wheel moves trickier but rear wheel stuff easier.
