SUPER SMOOTH TiN CERAMIC BEARINGS: Nano-technology Titanium Nitride coated ABEC 5 Grade bearing races with Si3N4 Grade 3 ceramic balls. Lighter stiffer & smoother and will last longer than other ceramic and steel bearings.

SUPER LOW FRICTION X-SEALS: Patented technology uses Low Friction Dual Lip Seals housed in the Premium bearings and CNC machined alloy cups. This allows the seals to fit very precisely and allow for less contact between the rotating parts in order to reduce energy-wasting friction. In addition, the seals provide better protection for the bearings since there is less space for the elements to get past the seals.
