i'm probably going to discuss my concerns this weekend. He also has my roubiax - which has yet to be fixed from the crash (needs new rear wheel - i have a spare)
I was think about $600-$800 based on the fact that I saw completed acution on e-bay for a XS one (otherwise identical) that went for $700.
It 's all orignal(look at the archive at Cannondale.com for specs) ,and has 73 miles(you also get a cateye computer, but no pedals)
