AC tubeless wheels take rim technology to the next level. Our mountain bikers are successfully riding and racing tubeless, and now this innovation is available for our AC road riders. Our tubeless wheels are set up with a base layer of AC fiber tape covering the spoke holes and two layers of AC honey colored tape to seal the rim. Next, install tubeless ready clincher tires and pump liquid sealant into the system through our proven AC valves. The liquid sealant replaces the conventional tube. You may ask how our tubeless system works. Bill Shook designed the rim with a bead barb running along the edge of the bead shelf. When installed, the tire firmly pops into position over the bead barb. The tire bead centers and tightly grips the circumference of the rim creating a sealed environment to hold the liquid sealant without burping.

The number one reason to run tubeless wheels is to avoid flat tires. In the event of a puncture, the sealant quickly fills and closes small holes in the tire preventing flats caused by glass, metal and other
debris. Pinch flats can not occur because a tube is not needed. Our tubeless system is about speed. It lowers wheel weight at the extreme outer edge of the rim resulting in lower rolling resistance
and better performance. In a traditional clincher set up, the tire and tube interface moves as the wheel rolls, creating friction and energy loss. With the AC tubeless set up, there is no frictional energy loss between the tire and tube because the tube is gone. Liquid sealant is lighter than a tube. You can ride lighter weight tires with our tubeless system because you don’t have to use tires made with heavy, inflexible puncture layers. Overall, our tubeless system is lighter and the wheel will spin up faster with less rider energy
output. And the best part is flat tires are past history.
