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 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. Keeping the weight low, but the new EX offers 14% thicker sidewalls for maximum dent resistance and a 33% thicker spoke bed for added pull-through strength. Increasing the outside width of the rim to 29.1mm and the interior width to 25.5mm the bead socket was reshaped for an even tighter seal and allowed our internal arch to add even more stiffness to the rim's structure. The new Flow EX: the strongest, fastest rolling, and best sealing tubeless rim available for 26-inch, 29-inch and 650b tires sizes just got even better.
Bead Socket Technology rims are designed to match the shape of your tire's bead to create a safer and more secure air tight interface. Unlike the secure "socket" of a BST design, conventional rim shapes drive the bead of the tire down deeper into the rim, putting pressure on sidewalls that causes friction, restricts tire volume, and keeps the interface from forming a sufficient seal for tubeless use. BST rims secure the bead of the tire, not the sidewall, creating an air tight seal while allowing the tire's sidewall to expand to its true, more round, more effective profile. The result is more traction and less rolling resistance. With lower-profile, less vulnerable sidewalls, BST rims are also lighter and stronger by design, and accelerate more quickly.
