With multiple World Cup and World Championship victories already in the books, improving the legendary Flow wasn't easy, but input from the best riders in the world and countless hours spent sweating even the smallest of details has led to a rim that redefines what even Stan's thought was possible. The Flow EX is lower, wider, and meaner, offering a lower profile sidewall and redesigned Bead Socket Technology for maximum durability and tire seal on even the most punishing of technical trails.
Specific improvements from the Flow to the Flow EX include a 14% thicker sidewall for maximum dent resistance and a 33% thicker spoke bed for added pull-through strength. By increasing the outside width of the rim to 29.1mm and the interior width to 25.5mm, the bead socket can now be reshaped for a tighter seal and allows the internal rim arch to add far more stiffness to the rim structure. In short the Flow Ex is the ultimate trail wheel, but light enough to be used on small travel frames and even XC hardtails.
The Flow EX rim features Stan's wheels core rim design, Bead Socket Technology (BST). It allows you to run most standard beads, tubeless ready and UST tires in a reliable tubeless environment. BST has allowed the masses to run tubeless without the mega-weight of a UST style set-up. The spokes are DT Swiss 2.0/1.7mm in black anodized with silver alloy nipples.
The hubs are the becoming-legendary Stan's 3.30 HD variety with a 20mm thru-axle. If you need 15mm or QR call our sales staff at 800-627-6664 so we can convert them for you. Wheels come pre-taped and have a 35mm Universal valve installed.
