One for all.
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 engagement is twice that of the Neo Ultimate hubs on the more expensive Grail Pro model, the standard Neo still boasts four pawls and a forged steel 36t ratchet ring for responsive engagement while punching out of grassy corners or remounting after obstacle-laden run-ups. If this were a mountain wheelset, we'd probably want the lower engagement angle of the more expensive hubs, but for skinny tire applications, the standard Neo's ten degrees are more than sufficient.
The hubs are finished with Stan's new SealLock end caps for easy installation and Slip-Fit axle ends for easy conversion, and the rims come complete with Stan's yellow rim tape and Presta valves already installed for tubeless use.

- Q & A
Not adequate for cyclocross
- Familiarity: I've put it through the wringer
These wheels are fine for pavement, gravel roads, and smooth dirt trails, but don't even think about racing cyclocross on them. These things are much more fragile than the Iron Cross. Mine were destroyed after Gloucester. It's surprising that Stan's markets these as cyclocross wheels, because they aren't.
Seriously, a $745 wheel with 32 spokes can't support a 201 pound rider?
