Based on the legendary Flow EX, the new Flow 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.
• Designed, tested, and raced to victories on the World Cup DH and Enduro World Series circuits
• Tie-beam triple-cavity rim design resists damage and prevents air loss under impacts
• 29mm internal width optimized for 2.35 to 2.8 Trail, All-mountain, and DH tires
