Now flush-mounted Dif-pads! Full-size performance in a small yo! This polished aluminum Dif-e-Yo yo-yo is a scaled-down version of the Dif-Fly, measuring only 1-7/8" in diameter. With a KonKave bearing and Dif-Pad response, the Zzzip-Fly is 1.200" wide and weighs 58 grams; with the rim weight O-Rings installed it weighs 66 grams. The KonKave .500" diameter earing is .188" wide and keeps the string centered on the axle, letting the Zzzip-Fly stay extremely smooth with long spin times and making it great for multi-layer string tricks.
