The Catalyst Stacked by YoYoFactory was part of the final run of the Catalyst model. 100% made in the USA, the Stacked Cat is sandblasted on the rims, while the bowl is polished. Engraving is minimal, with the Catalyst logo on the rim and YoYoFactory in the bowl. Weighing in at 72.4g with Z-Stacks installed, the Catalyst also ships with regular stacks.
The Catalyst uses CBC slim pads and a standard C bearing.
