Now flush-mounted Dif-pads! The Sportster is polished aluminum sporting red/orange o-ring rim weights and is a "modified" version of the Wide Load for players that prefer a slimmer yo-yo design. It has the Dif-e-yo KonKave bearing and friction sticker response; the Sportster weighs 58 grams, and with the rim weight o-rings installed it weighs 65.5 grams. The KonKave .500" diameter bearing is .188 wide and keeps the string centered on the axle while at the same time allowing it to move when needed for response. This bearing shape is an improvement over the grooved bearing for even smoother play and long spin times; it's also great for multi-layer string tricks because it forces the string layers toward the center of the bearing, keeping the layers away from the friction stickers and side of the yo-yo halves.
