The smooth and self-centering KonKave Bearing manufactured by Dif-e-Yo. The concave outer circumference helps keep your string away from yoyo inner sidewalls to decrease friction. KonKave bearings are also relatively quiet.
• Standard (original) Stainless Steel
• Ceramic for those wanting that extra little "edge" in performance.
Either way, a sweet little upgrade for your yoyo.
Choose from popular sizes to fit your yoyo: • Dif-e-Yo/YoYoJam Size: .25 x .5 x .188" (also known as Large "Size C") • Duncan Size: 5x10x4 mm (also known as Small "Size A") • Hspin Size: 5x11x5 mm
As always, please ask questions and confirm proper bearing for your yoyo if you are unsure about which size is correct.
