Stans Rear wheel of Flow EX3 Sram XDR

The Flow EX3 aims for high speeds and the most demanding trails and courses. With a proven pedigree in the Enduro World Series and World Cup DH races, it's the most durable and high-performing wheelset available. The Flow EX3 rim combines an internal width of 29 mm and a durable 6069 aluminium construction from the Flow MK3 with the incredibly robust triple cavity Tiebeam design of the classic Flow EX rim. The result is a rim shape that perfectly balances radial compliance with lateral stiffness and sets the benchmark for durability and impact resistance. The Tiebeam inner bridge of the Flow EX3 rim allows it to withstand impacts that would deform most rims to the point of losing air and suffering structural failure. Even if you're using a tire insert, huge impacts can cause a fold in the sidewall of most rims, resulting in air loss and potential failure. But the Tiebeam reinforcement and the patented low sidewalls of the Flow EX3 resist this folding, maintaining air pressure and structural integrity better than any other rim. The E-sync hub is designed for strength and durability. Whether you're racing in wet conditions, tackling rocky gardens, or leveraging the climbing torque of an eBike, the cromoly axle and double-row Enduro bearings of the E-sync can take it. The 6066 alloy shell and heat-treated steel ratchet ring provide brute strength, but clever details like a ratchet angle that reduces stress on the bearings and a flange design that balances spoke tension make this hub even more durable. And with an engagement of 8.18°, the E-sync hub is as fast as it is strong. Available with a Shimano Micro Spline, HG, or SRAM XDR freehub, and a 6-bolt or Centerlock brake style, with options to fit all popular axle configurations. Tubeless-ready with rim tape installed. The Flow EX3 is the evolution of the Flow range for aggressive riding. Every World Cup DH victory and in the Enduro World Series, every hour of testing, riding, and improvement, it’s all here in the Flow EX3. This wheel removes the limitations.
