A bar is only as good as the quality of its parts and processes. We use thermoplastics primarily used for the production of precision parts using the injection molding process. The colorless, semi-crystalline polymers are characterized by extreme rigidity, low frictional resistance, and amazing dimensional stability. Titanium is as strong as steel but 45% lighter. This gives titanium the highest strength-to-weight ratio of all known metals. Plus, titanium is impervious to salt. For these reasons, we've used titanium for the control bar truss, as well as the quick release and bar end grub screws. Marine-grade A4 stainless steel is used for the remaining metal components. The higher proportion of molybdenum minimizes corrosion and delivers years of reliable performance. Only the best stuff goes into the Sensor 3S.
