Improving a wheelset that's topped the podium at multiple World Cup and World Championship events is no easy task, but Stan's delivers with the Flow EX 29in Wheelset. Featuring a wider profile and lower, thicker sidewalls for increased durability compared to its venerable predecessor, the ZTR Flow, this wheelset takes all-mountain versatility to a new level. The Flow EX rolls fast over the most technical trails, resists damage from big hits, and boasts Stan's unparalleled tubeless reliability.
Billed as a bombproof trail, all-mountain, and enduro wheelset, the Flow EX features a wide 25.5mm internal rim width and 29.1mm outer width to provide a solid platform for your tire of choice. The Flow EX incorporates Stan's Bead Socket Technology (BST), featuring notably low-profile sidewalls that allows the tire bead to seat more effectively. BST results in an exceptional tubeless seal while also allowing the tire to hold greater air volume than standard rims, so the tire maintains 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 bunkered down in the dust wrestling with flats and more time shredding your favorite loops.
Stan's new Neo OS hub set sits at the center of the Flow EX, featuring oversized, smooth 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. 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. Stan's builds in its new SealLock end caps for easy installation and Slip-Fit axle ends for easy conversion.
The Stan's NoTubes Flow EX 29in Wheelset comes complete with Stan's yellow rim tape and valves already installed for tubeless use. Each wheelset includes endcaps for both 15mm and 20mm axles. Please note that these endcaps are only compatible with the Neo OS hubs, and are not compatible with standard Neo hubs.
