High-speed ball-bearings manufactured particularly for XRAY with low radial play. ID x OD x depth (mm) = 6x10x3. Group of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These best quality ball-bearings are fitted with unique plastic covers, and so are degreased and gently oiled with AeroShell Fluid 12 oil for maximum smoothness, longevity, greatest threshold and maximum performance. These ball-bearings have significantly more (and bigger) balls inside the cage compared to the regular ball-bearings, making them even more resilient under lots. The inside covers are really an easy task to eliminate for fast and comfortable servicing. These ultra-high precision ball bearings are made to withstand all extremes on course under racing conditions and/or simply fun racing.
