Most racers cares about the speed of the cars; therefore, the materials of the parts becomes very crucial elements. We understand this demand and that is why we keep trying to make our products lighter, so the whole new idea is to trim off the surfaces of the ball in order to reduce the weight and without affecting the function of the pivot ball.
This special design was original created by our develop team, and the reason to do that is because to trim off the surfaces of the ball is also reducing the friction of the measure of area, so that will keep it smooth and easy corporate with other components.
Nylon is a great material because of the strength and stiffness and use it for the pivot ball will helps the structures to handle the possible impact. Aluminum is light and it reduces the weight effectively. For speed requirement, we develop aluminum parts to reduce the burden of the cars.
