[Q]uantum

Top Yo - Quantum

Quantum combines a 7075 aluminum body with a stainless steel inner rim.

Quantum is machined from the standard 6061 aluminum, and sports an inner rim made of 7075 aluminum; an unusual combination for bimetal yo-yos these days. The body size is considerably large for its width, making this a "tall" class yo-yo. It pulls every ounce of power from its 67 grams of mass. While 7075 aluminum doesn't have the same density as stainless steel, it is denser than 6061, and has a noticeable effect on the yo-yo's weight distribution. The resulting body shape creates a unique sense of stability that feels well balanced with its profile.

The contrasting metals also make for a beautiful effect.
