American Classic Argent Tubeless Wheelset

By - In THE DOUBLE DIAMOND



Riders are obsessed with tubeless technology and we’ve unleashed the world’s fastest, most advanced deep tubeless road wheels for racing and training. Driven by vision and created by hard work, Bill Shook designed this breakthrough Argent tubeless wheel system emphasizing durability and stiffness in a concept Bill calls, “multi-plying lightness.” The wide aerodynamic rim is 22mm wide x 30mm deep and only 390 grams. Bead barb technology hooks on the tire bead to secure the tires in place without burping. Ride smaller, lighter tires because they spread out across the wide rim. Low spoke count Series 3 lacing for torsional stability and stiffness. Hand built Argent’s are championed for their quick accelerations, solid cornering, fast climbing and descending. When seconds count in the relentless pursuit to win, Argent wheels deliver the ultimate technological advantage.

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.

THREE GROUP SPOKE SYSTEM BALANCE OF SPOKE TENSION
Bill Shook obsessively engineers every wheel system to its optimal “sweet spot”, the balance of spoke tension, hub flange width, spoke angle and selection of the appropriate materials. After years of research and development, Bill Shook designed the American Classic three group spoke lacing for our 24 spoke rear wheel systems to build the strongest, stiffest and lightest road rear wheels in our line. We call this advanced system Series 3 for our 420 Aero 3, Magnesium, Road Tubeless, Aluminum Tubular and Carbon wheels. These good looking, hand built three group spoke wheels are at the forefront of performance, aerodynamics, comfort and durability.

 
The concept behind this lacing pattern is to create equal spoke tension for the drive and non-drive sides of the rear wheel, a state that cannot be reached in traditionally spoked wheels. Mathematically, this unique balance of spoke tension occurs on 24 spoked rear wheels. To achieve this balance, the rims are drilled in groups of three spoke holes. The spokes are laced to our finely crafted American Classic high-low 24 spoke hub, two on the drive side of the wheel to one on the non-drive side. The result is more spokes on the drive side where the wheel needs to be strongest, and fewer spokes on the non-drive side. Bill Shook calculated the optimal position for the non-drive side hub flange to create the ideal bracing angle of the non-drive side spokes. “The three group spoke design is a better use of materials achieving the balanced use of the spokes with equal spoke tension on both sides of the rear wheel,”says Shook.
 
The wheels are stiff and light to decisively dive into corners and power out, accelerate repeatedly, climb and descend with ease and hold speed on the flats. There are no broken spokes. No flexy feeling out of the saddle. When winning is your goal, the time-tested three group spoke wheel system delivers.
