The 31.8 clamp X 4.5" risers in the middle there are for sale.
I might build this thing up and ride it just because I'm too curious. Its somewhere between a DJ and street frame built around a 405mm fork. This might be my new 26" skatepark bike or I might sell it if it turns out too small (22.5" top tube). It will probably need some 7-8" bars.
