The Evolution G3 diabolo from Sundia has a new center which is an upgrade from the original Evolution G2. The axle's center has a metal sting tracking center with hard anodized aluminum cups, making up the rest of the axle and this greatly reduces the friction on the axle. It also reduces string discoloration, as the anodized center does not blacken the string.

This Sundia Diabolo "Evo 3" offers a five bearing design, that improves over the triple bearing as it can handle more force and spin for even longer. 

What really makes this diabolo unique is that is has a teflon inserted ring added to the cup. This is done so the point at which the string touches the inside of the cup it hits this teflon ring. This ring is very slippery, making adjusting the angle of the diabolo with the string is easier. This is important when doing 2-3 diabolos at the same time. This diabolo also has an increased outer weight distribution. The outside edge of the cup is thicker pushing the centrifugal force of the diabolo on the outside edge more. 

This is by far the most advanced diabolo made, and really makes a difference for advanced players. 

Comes with no sticks.
