Radial-laced 24-spoke front, 28-spoke rear and 26mm wide "all-mountain?" I don't think so.
Wrong wheels for AM. Check out Mavic Deemax's .
Radial lacing = silly idea (at least IMHO).

Depends what your definition of all mountain is. I'd agree with the others that Roval set isn't quite it, but perhaps could work for your riding if the price were right, but hard to know since you don't describe your riding or budget. Deemax is overkill for AM riding (plus it's a proprietary type factory wheelset, I wouldn't recommend one at all). Might peruse some of the "AM" choices at bicyclewheelwarehouse.com, too, for a good standard wheelset with a good build at a good price...
