American Classic 2016 Sprint 350 Tubeless Road Wheel Set
Sprint 350 Tubeless are great for climbing and fast rides, everyday or race use. Responsive, smooth and easy to spin up to speed. No gimmicks, hidden nipples or unusual spokes. Comfortable for long rides without compromising stiffness or acceleration. The Sprint 350 Tubeless rim is one of the lightest traditional aluminum road clincher rims in the world. Bill Shook used his design skills and geometry to make the Sprint 350 Tubeless semi-aero rims strong and light with a rim profile of 22.6mm wide × 24mm deep with a large inner width of 19.7mm. These wide profile rims translates into crisp accelerations, faster rolling on the flats and decisive cornering.
Bicycling Magazine said the Sprint 350’s are the, “lightest-per-dollar everyday wheelset we’ve ever found. They excel as race wheels too-not only because they spin up as quickly as you’d guess a featherweight would, but because the deepish rim wall gives just enough aero advantage for sustaining a long solo break at the threshold and despite its wispy weight and radial lacing up front (3-cross rear) the wheel doesn’t noodle in the corners.” Maximize your riding potential with Sprint 350 Tubeless.
Can be ridden with tubeless ready tires and sealant or with regular tires and tubes.
WIDE RIMS IMPROVE CYCLING PERFORMANCE
Everybody is talking about wider rims for both road and mountain bike. What does it really mean for you, the rider? There are a few wide rim profiles on the market but they are either heavy, or too light and flexy. Bill Shook used his mathematical abilities to design our revolutionary wide rims, attaining the goal of being light, stiff, strong, aerodynamic and wide, all in one rim. To start, wide rims mean riding lighter, smaller performance tires with cushiony, high air volume and firm surface grip. Larger width tires offer more air volume but they are heavy with a sluggish ride quality. The desired combined wheel and tire qualities are achieved by stretching out the smaller tire casing on a wide rim and effectively making the tire bigger. Also, smaller tires on wide rims reduce tire roll on the rims. With a narrow rim and a wide tire, the rim floats from side to side on the tire. Using a wider rim with a smaller tire minimizes float for improved handling, confidence and control. The rim is lower weight at the extreme outer edge of the wheel decreasing rolling resistance and boosting speed. Our wider, lighter rims translate into crisp accelerations, firm ground control, faster rolling on the flats and decisive handling for the extra edge needed by competitive athletes.
AC ROAD TUBELESS TECHNOLOGY
THE NEXT LEVEL
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 as the tube is not part of the system.
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.
