Built up as a 1992 with first generation Shimano XTR parts.  The frame is New Old Stock and had never been built before we got it.  The Valkyrie uses smaller diameter tubes which will absorb impacts better than one large diameter tube.  The elevated chain stays eliminated chain suck and allowed the chain to be removed without cutting.  The WTB roller cam brake was modified to allow for smoother cable routing by moving the rollers to the underside of the brake arms.
