Hi, I am 6'0 and right now i am riding a 56 cm IRO which fits me just fine. My friend who is 5'11 1/2 has a surly road bike which is 54 cm: granted he has a longer stem and higher seat post then me.
The reason why i am asking this question has nothing to do with my friend's bike or mine; I am curious about frame sizing because recently i saw the Macaframa DVD again and i noticed how many of the riders were riding frames which just barely fit them (their knees were like very close to the fork and they all had seat post (which came damn near eight inches out of the seat tube) uncomfortably high.
What am i missing? Is it that their geometry is so aggressive that the short length of the top tube is compensated by the low reach to the handlebars? On my bike my knees have at least 2 - 3 inches clearance from the handlebars but the riders in the video have like little to no clearance yet they all seem comfortable on their bikes.
Someone please explain this!? I mean i could fit on a 53 or 54 cm bike which would mean my knees would be mashed up against the handlebars and then hips would be so low on the seat tube, that i would need such a high seat post as well and my arms would be jammed up as well which is also quite silly.
