About the Act
The Act was SUS YOYO MECHANICS’ first dedicated 3A design, created for Yo-Yo Store REWIND instructor Shotaro Matsuda. Where the Trial uses an inner rim, the Act uses an outer stainless rim — placing maximum weight at the outer edge for longer spin times across the demanding multi-yoyo sequences of 3A. At 56.97mm diameter and 42mm width, it provides a slightly larger catch zone than the Trial while remaining narrow enough for 3A string management.
