Stan's NoTubes Flow EX3 Wheel, 29'', 12x148, 6-bolt, XDR

The Flow EX3 wheelset is built for high speeds and demanding trails, proven in Enduro World Series and World Cup DH races. It combines the 29mm internal width and durable 6069 aluminum construction of the Flow MK3 with the strong Tiebeam triple cavity design of the classic Flow EX rim, balancing radial compliance with lateral stiffness.

The Tiebeam inner bridge enhances durability, resisting impacts that cause deformation and air loss, maintaining air pressure and structural integrity. The E-sync hub features a cromoly axle and double row Enduro bearings for strength, supporting eBike torque. Its 8.18° engagement provides quick response, suitable for challenging conditions.
