Industry defining rim design and unbeatable tubeless technology have earned Stan's NoTubes a place at the top of the heap of tubeless wheels. Built for the trail, the Arch EX 29in Wheelset brings this bombproof and reliable functionality to the most technical, aggressive runs. Borrowing the burly internal arch design of Stan's gravity focused Flow and the light profile of the XC speed demon Crest, the Arch EX is a versatile wheelset up for almost any terrain. Compared the original Arch, the Arch EX weighs in lighter, sits wider, and enjoys even more durability. The Arch EX utilizes Stan's trademark Bead Socket Technology BST, featuring low profile sidewalls that provide a better seat for the tire bead and allow for a host of benefits compared to the higher sidewalls of standard rims. BST provides a reliable tubeless seal, of course, and it also allows the tire to hold a greater volume of air than 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. 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 sitting in the dust wrestling with a flat and more time rocking your favorite tracks. The rims are already fitted with tape and valves. Stan's laces the Arch EX 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 more expensive Neo Ultimate hubs, the standard Neo still boasts four pawls and a...
