The Stan's NoTubes Flow MK3 27. 5in Boost Wheelset builds on the reputation of its rock-star predecessor, the Flow EX, to set the new standard for all-mountain adventures. Bursting on the scene with wider rims to better accommodate the shifting trend towards ever beefier tires, this wheelset pairs a loss of grams with increased stiffness and durability to weather whatever the trail throws your way. The Flow MK3's internal rim width puffs out from the EX's already generous 25. 5mm to an even wider 29mm platform built to pair with tire widths ranging from 2. 35 to 2. 8in. As expected with any Stan's wheelset, the Flow MK3 incorporates Stan's Bead Socket Technology (BST), whose notably low-profile sidewalls allow the tire bead to seat more effectively with less of the tire trapped behind the rim. This leads to a heap of benefits compared to standard rims that constrict tires with their higher sidewalls. The tubeless seal is more secure, and the tire can hold greater air volume, which 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. BST already makes the same tire feel plusher, but running the tire tubeless allows for a 30% reduction in PSI. That makes for even better handling, more solid cornering, and a more forgiving ride. These rims are also compatible with standard tubes, with the lower sidewall drastically reducing pinch-flat risk by reducing the amount of material present for the tube to pinch against. This means less time bunkered down in the dust wrestling with flats and more time shredding your favorite loops. The Flow MK3 rims are laced to Stan's new Neo hubs, which feature oversized, smooth-spinning bearings that glide on a strong, stiff, swaged axle. The Neo holds the bearings at a wider stance for a claimed threefold increase in strength compared to standard hub designs, and it utilizes four precision pawls that simultaneously bite into a forged-steel 36-tooth ra...
