that ad is terrible.
full frame dimensions would help.
more and better pictures would help. detailed pictures to show condition of components and detail shots of the lug work etc... at least a complete bike pic where parts aren't being cut off the image.
has the bike been tuned/overhauled? dents/dings? rust? tube/tire condition? clincher/tubular? stem? chain? freewheel? speeds? pedals? dust caps on crank missing? different rims? have you shipped a bike before? who will be packing it?
