I bought this bike in Dec. Not really thinking about the fact that I wont be racing cross this year. My foolish impulse purchase is your gain.
I have ridden it once, maybe about 10 miles in the snow. Otherwise it's brand spanking new. Size is 49cm but the top tube is closer to a 53cm, at 5'7" it fits me really well.
here are the full specs http://allcitycycles.com/bikes/archive/nature_boy_853green
Take it off my hands for $1900 obo
