My 94' Specialized catalogue shows all the MTBs with QR seatpost bolts. Why not just get a nice anodised/polished nut and bolt if you don't fancy QR? Doubt there's a bike specific binder bolt out there that'll bridge the gap (other than the pitlock above!)
edit: Pro-bolt do nice looking stuff for motorbikes - might suit.
