Bontrager's R4 Tubeless Road Tire offers a gloriously supple ride and virtually eliminates the potential of pinch flats. Because there is no tube, you can run lower pressure for amazing comfort over even the roughest roads. This trick tire boasts a 127tpi casing, folding beads and a slick tread for minimal rolling resistance and an awesome grip in the corners. Race it, train on it, ride it every day, the R4 is your new favorite tubeless tire.
Tubeless tires are compatible with tubeless and standard rims. When used with tubeless rims, the tire and rim form an airtight chamber, allowing the tire to be inflated without a tube. This lets you run lower pressure for optimum comfort and control without fear of pinch flats. When used with standard rims, the tire can be mounted and inflated with a tube.
