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.

Two versions:

• 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.
