The last thing you want to worry about when flying through your favorite, flowy singletrack is an inopportune pinch flat getting in the way of your ride. Keep rolling with unbeatable tubeless reliability with the Stan's NoTubes Crest 27. 5in Boost Wheelset. These wheels are built light and fast, but their low weight profile is stiffened with the addition of Boost hubs. The Crests utilize Stan's trademark Bead Socket Technology BST, which 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 sitting in the dirt wrestling with a flat at the side of the trail and more time out on your favorite loops. The rims come equipped with tape and valves already installed. Stan's laces the Crest 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 forged steel 36t ratchet ring for responsive engagement.
