Neutral Axis Brake Caliper

The Neutral Axis Brake Caliper (NABC) is a new concept of brake caliper combining the characteristics of fixed- and floating calipers. In the NABC the brake pad is connected to the fork leg via a strut. Moving the braking forces outside the caliper allows for making it lighter, simpler (perfectly symmetrical) and open on the sides, thus improving ventilation and pad cooling. As a consequence, stronger and longer brake torques can be sustained by the caliper, eventually leading to replace twin disc brakes with single disc brakes.
