Alchemy YoYos Catalog:

 

The CU is a sub minature yo-yo with the characteristics of a full sized yo-yo.

 It is only 1.5" in diameter, making it equal in diameter to the Tom Kuhn Pocket Rocket, and the smallest performance yo-yo on the market today. 

It is a rim weighted yo-yo made of stainless steel and has no protrusions from the center of the hub.

Even at it's small size, it's 66 gram weight makes this yo-yo eminently playable. The lack of the hub nub allows ample room for thumb grinds

FHz Hub Stack Kit Upgrade
Price: AU$15.00ea

The FHZ Stack Kit adapts a Freehand Zero, and many other yo-yos that use a 4mm bolt to use YoYoFactory Hubstacks. It does not come with bearings, plastic stacks, or o-rings.

The kit comes with two threaded axles of different lengths, two FHZ Stack nuts and four shims. Since plastic yo-yos are slightly inconstant, depending on the yo-yo you have, you may need to use one of the shims under each the nuts to allow the stacks to spin properly.
