NoTubes say:flow ex

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.

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 we thought was possible.

The new 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. We kept 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 let us reshape the bead socket for an even tighter seal and allowed our internal arch to add even more stiffness to the rim’s structure.

DCR says:

This is a hugely wide rim, great for taking really chunky tyres. NoTubes are among the great pioneers or wider rims. Their shallower beds and sharper hooks also make their rims ideally suited to tubeless systems. Their welded joints help to keep the weight down as well as carefully optimised profiles. 490g isn’t that heavy for a rim generally but considering the applications this rim is capable of undertaking, it is remarkable.
