The optional internal disk offers two benefits. The first is stiffness. With the disk installed the wheel will be stiffer which is very desirable on tracks with large jumps, high traction, high speeds or high ambient temperatures. The second benefit is balance and weight. With the disk installed dirt cannot buildup inside the wheel and throw off the balance and add unwanted rotating mass. Last but not least the new EVO wheel is 6.5% lighter than the previous AKA truggy wheel.
