Duncan Cold Fusion
The Cold Fusion is a must-have for any serious player, collector, or enthusiast. It uses a special, high-speed ball bearing, and features Brake Pads for smooth, reliable response.
The Cold Fusion Yo-Yo is made of aircraft-grade aluminum and features a ball-bearing axle. It is one of the longest spinning yo-yos in the world. Holder of previous World Records for spin time, the Cold Fusion is capable of a spin time of over 10 minutes. (Remember that you’ll probably need months and months and months of practice to pull this off.)
