Dobo,
Yeah they both the the flatend top tubes, which actually makes quite alot of difference when carrying.
And the cables are all underneath the down tube, and then go through a cable guide on the bottom bracket shell. (apart from the rear brake cable with goes onlong one side of the top tube)
Now Which is Best……..
The Cyclo-X is slightly lighter due to the carbon rear end, but there's not much in it. However because of the carbon rear end there is a bar that goes between the seat stays just behind the bottom bracket for re-enforcing. This sacrifices mud clearance, and because the X-Wing doesn't have the bar it is better (in my opinion).
Geometry is exactly the same, and they feel pretty much identical to ride, but for some reason i always go for the Red X-Wing first…
Hope that helps,
Josh…
