Based on the legendary Flow EX, the new EX3 rim features Tiebeam, an internal reinforcement that offers unmatched impact resistance and the best air retention of any tubeless rim. The Flow EX3 combines the incredibly durable Tiebeam design of Stan's classic Flow EX with the 29mm internal width and 6069 aluminum construction of the popular Flow MK3 to create an entirely new rim built to handle today's faster, heavier, and more capable enduro, downhill, and e-bikes.

• Reinforced 29mm width rim shape optimized for 2.3-2.6” tires and built to handle AM, DH, Enduro, and anything else
• Designed, tested, and raced to victories on the World Cup DH and Enduro World Series circuits
• Tiebeam triple cavity 6069 welded aluminum rim resists dents and air loss during impacts
• Patented Bead Socket Technology offers easy inflation and the most reliable airtight seal
