29" ALLOY FRONT WHEEL ONLY
The Flow EX3 rim combines the 29mm internal width and durable 6069 aluminum construction of the Flow MK3 with the incredibly strong Tiebeam triple cavity 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 Flow EX3 rim’s Tiebeam inner bridge lets it withstand impacts that would deform most rims to the point of air loss and structural failure. Even if you use a tire insert, huge impacts can cause the sidewall of most rims to fold, causing air loss and eventual failure. But the Tiebeam brace and patented low sidewalls of the Flow EX3 resist this folding, maintaining air pressure and structural integrity better than any other rim.
Based on the legendary Flow rims that have won World Cup DH and Enduro World Series events, Flow S2 wheelsets are a great upgrade for riders looking for better tubeless performance and excellent durability. Patented Bead Socket Technology means easier tubeless inflation and more confidence on the trail. An emphasis on durability means a reinforced and eyeletted spoke bed, a quality sleeved joint, and 6061 alloy construction. A 30mm internal width makes the Flow S2 ideal for 2.3-2.6” tires.
The E-sync hub is built for strength and durability. Whether you're racing in wet conditions, attacking rock gardens, or putting down 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 smart details like a pawl angle that removes stress from the bearings and a flange design that balances spoke tension make this hub even more durable. And with 8.18° engagement, the E-sync hub is as fast as it is strong.
Available with a Shimano Micro Spline, HG, or SRAM XDR freehub. Tubeless ready with rim tape and valve stems installed.
The Flow EX3 is the evolution of the Flow line for aggressive riding. Every World Cup DH and Enduro World Series win, every hour of testing, riding, and improving, it’s all here in the Flow EX3. This wheel erases limitations.
