Boasting Boost axle widths for an extra hit of power transfer and tracking consistency, the Stan's NoTubes Arch MK3 27. 5in Boost Wheelset gains inspiration from Stan's XC speed demon Crest's rim profile and gravity-focused Flow's burly internal arch design. With a revamped rim profile, this versatile wheelset clocks in stronger, wider, and lighter than its revered predecessors. The MK3's internal rim width bumps out from the EX's 21mm to a beefy 26mm platform designed to pair with 2. 25 inch to 2. 5 inch tire widths. As with every Stan's wheelset, the Arch MK3 utilizes Stan's Bead Socket Technology (BST) with its notably low profile sidewalls that allows the tire bead to seat more effectively, which brings a heap of benefits compared to standard rims with higher sidewalls. BST results in an exceptional tubeless seal while also allowing the tire to hold greater air volume than standard rims that place the bead 2-4mm below the edge. This interface allows the tire to maintain its full shape for a wider, more stable rolling platform compared to the same tire mounted on a standard rim. The ability to run up to 30% lower air pressure in the tubeless system than a standard tube setup paired with all those BST features results in exceptional tire stability, better handling, confident cornering, and overall improved control out in the dirt. For riders not quite ready to make the tubeless leap, these rims are also compatible with standard tubes, with the lower sidewalls drastically reducing pinch flat risk by limiting the amount of material present for the tube to pinch against. This means less time hunkered in the dust wrestling with flats and more time ripping your favorite loops. Stan's Neo hub set sits at the center of the Arch MK3 with oversized, smooth-spinning bearings that glide on a stiff, strong, swaged axle. The Neo cradles the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs and utilizes four precisio...
