Review on Bones Reds High-Performance Skateboard Bearings (Set of 8 with 4 Spacers) by David Garnic

Bearings roll smooth and quiet. The red stamp looks good. They also run fine. The local rink owner advised me to lift the clear plastic ball holder on the back and add a drop of oil. Had he not done so, he would have been denied the lease prematurely. But he's never seen a mistake with a drop of oil. It can be difficult to get the balls back in place if you lift the plastic holder too high. After that, they're much quieter, they don't spin for as long, but you don't notice that when driving.
