The folks at China-based KC Agent (you remember, two Chinese National Champions who released that 7075 yoyo with titanium rims) are back with a new yoyo, this one designed for 4A!
KC Agent spent a full year and many prototypes developing the Core, a 4A yoyo with fully interchangeable parts to allow for easy replace/repair of any components that take too much of a beating. And for 4A yoyos, it ALL takes a beating.
Check out more pics, specs, and a video featuring Chen Zhao below. The Core is available direct from KC Agent right now, and should be hitting other retailers soon.
