About the SUS 003 Transmission Cross Ratio
The Transmission Cross Ratio takes the SUS 002’s undersized philosophy into bimetal territory. At 51.94mm diameter with 76% of total weight in the stainless steel rim, the yo-yo generates spin power far beyond what its compact size suggests. The “close-ratio” name references automotive gear theory — optimized power delivery across a narrow range. Colorways follow a custom automotive paint theme.
