A newly developed speed sensor disc sends 18 signals per rotation of the wheel to the system and measures the speed 18 times more accurately than any other system available on the market. In this way, the system is able to react significantly faster and more dynamically to changing requirements and recognises acceleration even at slow speeds, e.g. hill starts.
The speed sensor disc sits snugly against the disc brake rotor. The product is the speed sensor disc only and not the disc brake rotor itself.
