Stan's No Tubes Flow S2 Rim

The 30mm internal rim width is optimized for tires between 2.3 and 2.6 inches. This range provides a stable platform that balances sidewall support with the traction benefits of a wider profile.

The Flow S2 rear wheel is available with hub compatibility for both Shimano HG11 and Shimano Micro Spline systems. Please verify your current cassette type before purchasing to ensure a proper fit.

Stan's patented Bead Socket Technology is designed specifically to make tubeless setup straightforward. The rim shape allows the tire bead to snap into place easily, often requiring only a standard floor pump rather than a compressor.

Yes, the Flow S2 is built for durability. It features a 6061 aluminum construction with a sleeved joint and stainless steel eyelets, which reinforces the spoke bed against the high-stress loads typical of enduro and downhill racing.

The E-sync hub offers 8.18 degrees of engagement. This fast engagement provides immediate power transfer when you start pedaling, which is particularly helpful for technical climbs and navigating tight trail sections.

This wheel uses high-quality Enduro bearings, including a double-row freehub bearing. This setup is specifically engineered to handle the increased torque and side loads common in modern mountain biking, resulting in better longevity and smoother performance.
