I'm 5'11 and this is a 56 (although I took off the sticker), same as on my old trek. I don't know where that would put you. I main reason for this bike is that I ide rough roads, like to go fast (and can get pretty fast) and probably do about a century a month. If I didn't ride 100 mi or more I might have gone with something different, but I love the all-around nature of this. If I didn't say that my back gets tired at mile 80 or 90 sometimes I might have ended up without any spacers, and may still take some out. Which I think is really cool. No way I ride a Sott addict without spacers...
