The Grail Team Disc Wheelset is Stan's NoTubes' answer to the call for a versatile wheelset that can handle a wide variety of tire pressures and disciplines. Whether you're slicing through mud in a local 'cross race, attacking a road race climb, or embarking on a gravel adventure, the Grails are up to the challenge with Stan's renowned tubeless reliability along for the ride. These wheels utilize the BST R rim profile, a twist on Stan's signature tubeless technology that's compatible with tires ranging from 25mm to 40mm wide. The Grail's BST R shape was designed specifically to handle narrower tires and higher tire pressures for a resulting wider PSI range than standard BST rims. Similar to standard BST, BST R features low profile sidewalls that provide a better seat for the tire bead and allow for a heap of benefits compared to standard rims with higher sidewalls. When setup as tubeless, BST provides an exceptional seal while allowing the tire to hold a greater volume of air than standard rims that place the bead 2 4mm below the edge. This interface lets the tire maintain its full shape for a wider, more stable rolling platform than if the same tire were mounted on a standard rim. Pairing BST with the ability to run up to 30% lower air pressure than on a standard clincher wheel results in more stability, better handling, solid cornering, and better overall control. These rims are also compatible with standard tubes, and the lower sidewall drastically reduces pinch flat risk by reducing the amount of material present for the tube to pinch against. This means less time running to the pit with a flat and more time battling for position out on the course. Stan's laces the Grail Team Disc rims to its new Neo hub set featuring smooth spinning, oversized chrome bearings that glide on a stiff, strong, swaged axle. The Neo holds the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs. Though its ten degree engagemen...
