    Ride from morning to night.

    Built tough enough to pedal all day without weighing you down, the Stan's Notubes Flow S1 27.5 Boost Wheel tags along on challenging rides with no shortage of support, stability, and responsiveness. The Flow was developed from rims ridden in Red Bull Rampage, which explains its 1.6mm-deeper profile and reinforced rim walls to offer greater impact-strength with only a minor weight gain, while the wider-set hubs deliver added clearance and a stiffer build for more response and stability out on the trail.

    The Flow S1's 6061 alloy construction serves an optimal strength-to-weight ratio that rips trails all day without substantially sapping leg energy, while the faster-engaging, CNC-machined Neo hubs with 10-degree engagement help you get up and over obstacles and through tight sections quickly and easily. The 29-millimeter internal width keeps up with the industry's push towards wider tires, ideally fitting trail and all-mountain tires from 2.3 to 2.8 inches—all without deforming the tire into a bulbous or bell-like shape that's more susceptible to slashes and burps.

    Bead Socket Technology (BST) boastsnotably low-profile sidewalls that allow the tire bead to sit more effectively and leads to a handful of benefits that don't come in standard rims with higher sidewalls. BST results in an impressive tubeless seal while also allowing the tire to hold greater air volume than standard rims that place the bead 2-4mm below the edge. This interface enables the tire to maintain its full shape for a wider, more stable rolling platform compared to the same tire mounted on a standard rim.

    Well done Stan

    Stan's Flow's continue to be the answer for the best bang for your buck wheelset out there. Decent weight, tubeless ready, super easy to set up tubeless. Plenty strong. And you can just about consider them disposable at this price! The Neo hub is surprising loud if your are into such things, and have very little drag. One thing worth noting is that the s1 does not come stock with valve stems.
