After clocking up multiple World Cup and World Championship wins, any update to the legendary Flow would have to be perfect. Following input from the best riders in the world and countless hours spent sweating the small stuff, Stan's No Tubes developed a rim that is beyond what they thought was imaginable.
Redesigning the MTB Rim
The new Flow EX is, simply, better than ever. Featuring lower profile sidewalls for ultimate durability and incorporating Bead Socket Technology for superb tubeless performance, this Flow EX MTB Rim can take the punishment of the most violent and technical trails.
Stan's No Tubes kept the weight down despite increasing the sidewalls by 14% for maximum dent resistance alongside a 33% thicker spoke bed for increased pull-through strength. Beefing up the eternal rim width to 29.1mm and the internal rim width to 25.5mm gave room to reshape the bead socket to produce a tight seal. Overall, the rim is now more comfortable, durable, and stiff.
