About the Trial
The Trial is a competition bimetal developed by SUS YOYO MECHANICS for Yo-Yo Store REWIND instructor Yuki Takami. Unlike conventional outer-rim bimetals, the Trial uses an inner-rim stainless steel construction that positions the added mass closer to the axle, producing a different spin character suited to 3A pair play. The rounded rim profile accommodates the hand-contact demands of 3A combinations.
