The ORIGINAL string centring bearing that changed yo-yo bearings forever.
The KonKave bearing by Dif-e-yo features a grooved centre so that it keeps the string centred and away from the sides. Provides incredibly smooth play and is often regarded as one of the best bearings on the market to date.
Rather than just repurposing bearings for yo-yos, Dif-e-Yo bearings are manufactured to custom tolerances from high quality Stainless Steel specifically for your yo-yos.
This bearing is Size C.
