With multiple World Cup and World Championship victories already in the books, improving the legendary Flow wasn't an easy task. It called for input from the best riders in the world and countless hours spent putting even the smallest of details under the microscope. The result is a rim that redefines what even Stan's NoTubes thought was possible. The new Flow EX is lower, wider, and meaner, offering a lower profile sidewall and redesigned Bead Socket Technology (BST) for maximum durability and tire seal on even the most punishing of technical trails. The new Flow EX offers 14% thicker sidewalls 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, Stan's was able to reshape the bead socket for an even tighter seal and allowed for an internal arch to add even more stiffness to the rim's structure.
