●Straight Edge Frictionless Shields- pop off resistant - holds oil in, dirt and moisture out- easy to clean
●Micro Groove Raceway Surfaces- linear micro-groove surfaces improve bearing lubrication, speed and spin
●Max Impact Cage Design- non- distortion custom cage keeps the balls precision spaced & oil circulating
●Balls Out Technology- eliminates shield and cage contact on impact for a go fast, stay fast bearing
●High Speed Ceramic Oil- nano-ceramic compounds for wear protection . moisture, rust, corrosion resistant
●Factory Fresh Quality- nitrogen flled shrink wrap, reduces metal & oil oxidation until ready to be ridden
