IQON

The Iqon bearings are specially designed for the D3COD3 frames of the same brand. As they are smooth on the inside due to their multiple wheel assemblies, it is the bearings that have the inner treads raised towards the outside to adjust with the frame and keep the wheel separated from the frame without rubbing. We can use these bearings in other brands of frames with the same system as the Ones Skates slides or even for some wheels in Yoyo frames. 
People who have tried these bearings recommend them, that's a good sign. 
You can find them in different formats of 12, 16 or 20 units, although we also sell them loose in case you don't need so many.
At the moment there are two models, stainless steel and ceramic.
