Choose Holesom's California ABEC 7 Bearings Skateboard and Longboard Bearings for a great ride!
Holesom's California ABEC 7 bearings have a bearing spacer built right into them which extend slightly on the outside of the bearing so that you do not need speed rings either. There is an extremely tight feel between the bearings and the wheel. The energy between turns is absorbed by the wheel and not the bearing itself reducing impact and side load. Ultimately, you will have a bearing that will endure the demands of a downhill racer or any skateboard discipline.
