BST designs the tooling, molds, wheel and hubs, then manufactures them in its state-of-the-art factory. Precision cutting machines, like those used in the aeronautical industry, ensure that the process is repeatable and meets the highest certification standards. BST uses only the finest “prepreg” carbon fiber, which is embedded in a top-secret resin matrix epoxy. Carbon-fiber layup is done in a dust-free and temperature-controlled “clean room.” The wheels are cured in a superheated steam oven, or autoclave, at 260 degrees and 85 psi. This produces the best material compaction and smoothest surface finish. Every step of this process is logged, the entire history of each wheel is stored and stamped with a unique serial number. To ensure the highest quality manufacturing processes and components, BST’s entire operation is managed under strict, new ISO 9002 standards.
BST works with it's suppliers to ensure we get the best and most advanced materials for our wheels. Since December 2011 BST has been using carbon from Umeco Structural Materials (USM) that is impregnated with the EF1808 resin system explained like this:
"The EF1808 resin formulation resulted from a dedicated research program undertaken by USM to develop a significantly toughened epoxy prepreg resin with improved flow and handling characteristics, but without the reduction in temperature resistance that so often results. The development of the epoxy prepreg resin and the way it interacts with the continuous reinforcement fibers necessitated investigation of the resin polymers at the molecular level where measurements are made in millionths of a millimeter. This detailed understanding of the resulting composite structures was the key to achieving significant improvements in the product’s performance."
The new system in its fully cured condition displays improvements
of more than 30% in both damage tolerance and fracture toughness
(as measured by Compression Strength After Impact and G1c Fracture Toughness respectively) whilst maintaining its temperature
90-Degree Valve Stems
All BST wheels come with aluminum 90-degree valve stems that are not only easy to access, but keep centrifugal force from opening their Schrader valves and deflating tires during high-speed operation. Track tested up to 274 mph.
BST products have undergone decades of research, development, testing and the most stringent certifications processes. They’ve been flogged at Rim Technology, Eurotype Test Centre and have passed all lab and street tests for certification from Germany’s TüV to the U.S. Department of Transportation, with flying colors.
BST wheels have been proven internationally at every level of FIM Grand Prix roadrace competition and in winning 12 championship titles around the world.
The hubs are attached to the wheels using a unique fastening system that combines high-tech aerospace fasteners, mechanical locking mechanisms and super-high-strength aerospace adhesive. In the event of rim damage the hub can typically be salvaged and the carbon rim replaced at a substantial savings over purchasing a new wheel.
