TwinCam ILQ9 Pro inline skate bearings are used on K2's highest end inline skates. Rather than being shielded on both sides, one side is open for reduced weight and ease of service and lubrication. Great quality rollerblading bearings with the durablity of TwinCam. The ILQ9 rating is similar to that of ABEC, but specific to inline skating as designed by TwinCam.
