Using FRX5 wheels in the Hammer Fest downhill event on Vancouver Island this spring, pro rider Dharma Fontaine hit a rock that flattened his rear tire early in the race. “At the finish line, after I stopped shaking and rattling, I checked the wheel expecting to find massive damage,” he said.
Made of DuPont™ Zytel® nylon, trail bike wheel withstands sharp impacts that cause permanent damage to conventional wire wheels.
“I was stoked to see a very small insignificant ding beneath the destroyed tire. These wheels really are bombproof!” Severe impacts like that usually cause permanent rim damage to traditional wire spoke wheels, according to Fontaine.
Other advantages of the FRX5 over traditional wheels include fewer flats, reduced flat spots and less maintenance. It never requires truing, tension or alignment procedures needed for wire spoke wheels, according to George Kotzeff, president of TAG Wheels.
To make its innovative new wheel, TAG Wheels relies on DuPont™ Zytel® 8018. “Extensive testing in the lab and in the field, shows that this material gives us just the right combination of impact resistance, strength, stiffness and moldability,” said Kotzeff. The resin consists of PA66 polymer modified with advanced DuPont toughening technology and reinforced with glass fibers (14 percent by weight).
The FRX5 is an innovative, one-piece design that optimizes structural strength, impact resistance and functionality. Wall sections vary in thickness to provide additional strength and stiffness where needed. Each spoke has an internal rib. The hub shell is a robust, thick-walled construction, and it is keyed to optimize shear resistance and torque transfer, according to Kotzeff. The design minimizes pinch flats with a relatively thick, flat-topped bead and a resilient rim. The rear wheel has an integral chain-catcher feature to combat chain binding.
TAG Wheels manufactures FRX5 wheels using a patented lost-core molding process that makes possible its complex geometry and strong hollow structure. The manufacturing process starts with molding a metal mandrel from a low-melt-point alloy. This mandrel is then over-molded with Zytel® 8018. The mandrel, or core, is then melted out leaving behind the hollow-formed composite wheel. TAG Wheels supplies FRX5 composite wheels with high-quality DT Swiss 440 hubs.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
