High-speed ball-bearings manufactured specifically for XRAY with low radial play. ID x OD x thickness (mm) = 6x10x3. Group of 2 pieces. Top-quality professional ball-bearings for a super-free, super-smooth drivetrain. These best quality ball-bearings are fitted with unique plastic covers, and therefore are degreased and lightly oiled with AeroShell Fluid 12 oil for optimum smoothness, endurance, greatest threshold and optimum performance. These ball-bearings have significantly more (and larger) balls inside the cage than the regular ball-bearings, making them a whole lot more resilient under lots. The side covers are really easy to remove for quick and comfortable servicing. These ultra-high accuracy ball bearings are created to withstand all extremes on track under racing conditions and sometimes even simply fun racing.
