Uhmmm.."cross" frame??.....I wonder if it was crashed, causing that crack and maybe destruction of it's fork. What's ironic is, it would probably have been more repairable (by outfits like Calfee) if the damage was with it's CF tube(s).
It's a nsaty crack that already went two directions. I say it's toast....but there are really interesting details on that frame that it will make a nice wall ornament.
