what about this?

the wheels are a little off - they should take up pretty much the whole box. but for a 58 cm, the head tube to the rear dropouts should be about 39", so it'll fit. that leaves 6 inches, which only leaves enough room for one wheel, if any at all... I'll have to actually put it together to be sure.. should be able to rig something up from a used bike carrier box.
anyone tried this?
