It just keeps going.

Tough enough to handle some of the most demanding trails, yet light enough to ride all day, the Stan's Notubes Flow S1 29in Wheel eats all-day, challenging rides for breakfast, lunch, and dinner. Developed from rims ridden in Red Bull Rampage, it's no wonder the Flow S1 has a 1.6mm-deeper profile and reinforced rim walls to deliver greater impact-strength with only adding a little bit of weight to your ride. Then, the faster-engaging, CNC-machined Neo hubs help you get over obstacles and through rock gardens quickly and easily. 

With longer rides in mind, Stans gave the Flow S1 a 6061 alloy construction to ensure an ideal strength-to-weight ratio that crushes trail all day without draining leg energy. The 29-millimeter internal width supports 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. Meanwhile, Bead Seat Technology (BST) brings you a proper seal and secure fitment for added peace of mind when you're roosting berms at high speeds and navigating steep, rocky descents.

  • Robust wheel ready to rip technical trails for hours on end
  • 6061 alloy sheds weight without compromising strength
  • 29mm internal width supports tires from 2.3 to 2.8in
  • Bead Socket Tech (BST) enables secure tubeless set-up
  • Tubeless-ready with rim tape and presta valve
  • Neo hub with responsive 10-degree engagement

Broken Spokes

  • Familiarity: I've put it through the wringer

I've broken three spokes on this wheel in a month. The last one I didn't hit anything. All the spokes are breaking at the nipple which is odd. The rim is fine but the build seems inadequate.


  • Familiarity: I've put it through the wringer

Put this wheel on a rigid single speed to help me get use to riding rigid. I have made some BAD mistakes, going off jumps and landing flat like i'm on a downhill rig, slamming in to roots, night riding with bad lights and rim striking on who knows what... but this wheel shows no signs of wear. It's a little heavier than other options but corners great and can't be beat for the price.
