With the Flow rim, tubeless protagonist Stan's already has an all-purpose product for all-mountain riding on offer when it comes to giving a bike a light, stable wheel for wide tires. For lightweight riders or riders with high riding skills, this rim even extended into downhill use. Sabrina Jonnier, for example, repeatedly stood on the downhill podium with a bike fitted with such a flow rim.

Large rim width
The American manufacturer Stan's is now launching an adapted version of the Flow Ex rim and is clearly shifting the area of application towards enduro biking. "Flatter and wider" was the motto: the new rim is 8 millimetres less high than the Flow version, but the inner rim width - i.e. the mounting point of the tire bead - has increased from 22.6 to 25.5 millimetres. On the outside of the rim, the Flow Ex rim now measures 29.1 millimetres, 1.1 millimetres more than its all-mountain counterpart.

Less bumps
In order to be prepared for the rough gait of long-stroke fullies, Stans's has given the Flow Ex 14 percent thicker sidewalls on the rim flank, which should provide better resistance to dents. The flatter but wider profile also allows an even tighter fit of the tire in the rim and at the same time increases the air retention of the tubeless system.

26", 29" and 650b
The new product has nothing to hide when it comes to weight, with the black 26-inch model weighing in at 490 grams. In the black 29-inch version, the aluminum bow weighs 545 grams, while the 650b model weighs 520 grams.
