From the viewpoint of cost and durability, most normal sprockets, except for some competition vehicles, use very heavy sprockets made of steel. In order to bring out the performance of your car, aluminum is the best material for sprockets. The weight is approximately 1/3 that of steel. Since it rotates at extremely high speeds, it is essential to reduce weight. The shape is designed to prioritize performance and design over cost, so you can expect it to dress up your car.
