WHEEL TETHERS
Safety in motor racing sport leaves no room for compromise. As a leading manufacturer, Cortex Hümbelin AG develops and produces wheel tethers for all the reputable teams - from the junior racing classes through to Formula 1 and LMDh. An excellent performance-weight ratio combined with extraordinarily high cutting resistance is the basis for this success. With our expertise and many years of experience in development and production, our FIA homologated wheel tethers offer the highest degree of safety even in the event of serious accidents.
