Built for aggressive all-mountain action, SRAM's Rail 50 wheels balance the strength and stiffness you need with the lightness to climb quickly back to the top. Lean it over and carve corners on the 28mm outside rim width that makes big tires feel even bigger. Ditch the tubes with full UST tubeless compatibility, and reap the rewards of excellent traction, control, and fewer flats. And, the Rails are packed even more great features, like the Solo Spoke design that uses one spoke length to fit the entire wheel and 15 and 20mm through axle endcaps that can be interchanged without tools.
Universal Standard for Tubeless (UST) rims are compatible with UST tubeless, tubeless-ready, and standard tires. When used with UST tubeless tires, the tire and rim form an airtight chamber, allowing the tire to be inflated without a tube. When used with tubeless-ready tires, a sealant (sold separately) must be added to the tire to create an airtight seal. For standard tires, a tube can be used. With the tubeless setups, you can run lower tire pressure for optimum traction and control without fear of pinch flats.
