These Root Industries bearings are genuine ABEC-11 rated & certified, and are double sealed to protect them from dirt and dust. The nature of scooting means that a lot of sideways pressure is applied to the ball bearings. The Root Industries ABEC 11 bearings have been specifically designed to withstand more of the pressures that scooting puts on bearings, so if you're serious about speed, or just want to glide forever then these are the bearings for you.
