Fresh high-speed ball-bearings produced specifically for XRAY. ID x OD x depth (mm) = 10x16x4. Group of 2 pieces. Top-quality professional ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings are fitted with unique plastic covers, and tend to be also degreased and very carefully oiled with AeroShell Fluid 12 oil for optimum smoothness, longevity, highest threshold and maximum performance.
These ball-bearings have significantly more (and larger) balls in the cage compared to the regular ball-bearings, making them far more resilient under lots. The medial component covers are really easy to remove for fast and comfortable servicing. These ultra-high precision ball bearings are created to withstand all extremes within track under racing conditions and on occasion even merely fun battle. A "must have actually" device!
