The Stan's NoTubes Flow EX3 Wheel is a 29-inch rear wheel built around a 6069 aluminum rim with a 29mm internal width and a Tiebeam triple cavity design carried over from the original Flow EX rim. This construction targets enduro and downhill use, where rim strength under repeated hard impacts matters as much as weight.
The wheel builds around a Stan's E-sync hub with a SRAM XDR freehub, a 12x148mm TA rear axle, and a 6-bolt rotor mount, laced with 32 Sapim D-Light spokes and Sapim Polyax nipples. It ships tubeless ready with tape and a valve pre-installed, and pairs with 2.3 to 2.6 inch tires at recommended max pressures of 39 and 34 PSI.
