This is the signature yo-yo of Hajime Miura, who has won six consecutive world championships, and in 2018, won two categories simultaneously.Inspired by his unparalleled career in the history of yo-yos, in which he controlled two yo-yos in the two categories in which he won, Yoyorecreation took on the challenge of simultaneously developing a bimetal and off-string yo-yo of the same shape. This is the Bi-Metal version.The result is a yo-yo that can compete in competitions with one or two of each.In the double-handed division, where a slightly narrower width is considered mainstream, Yoyorecreation adopted a width that they believe is the maximum value that can withstand use in competitions. As a result, they settled on specs that overlap with the core of various single-handed styles.It feels moderately heavy enough to support long combos, but not sluggish, allowing for supple movements.Specs:Weight: 66.5g/2.35ozWidth: 43mm/1.70inDiameter: 56mm/2.2inBearing: Size C (12.7x6.35x4.76mm)Pad Size: YYR Size C
