that's my purstuit. i LOVE the way it handles. and when i say LOVE, i mean i would have sex with this bike if there was a suitable orifice.

you can't tell from the pic, but the top tube DOES slope, and the front wheel IS smaller than the rear...also it's about a 50cm seat tube, so the slope isn't all THAT dramatic...definitely not as dramatic as that other bike...i should really get taller frames...

oh wait...yeah, the topic...umm...650 rear/700 front would be bad. very bad, yes, unless the frame was built for it...maybe some nice builder would put it together for you on the cheap...then again, probably not. it also wouldn't be legal to ride on the track, but you probably don't care about that...even 650c fronts aren't legal anymore...stupid UCI...
