Brand new high-speed ball-bearings produced particularly for XRAY. ID x OD x depth (mm) = 5x10x4. Group of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These finest quality ball-bearings are fitted with special plastic covers, and tend to be degreased and lightly oiled with AeroShell Fluid 12 oil for optimum smoothness, long life, highest threshold and maximum performance.
These ball-bearings have more (and larger) balls within the cage compared to the regular ball-bearings, making them alot more resilient under lots. The medial side covers are really easy to remove for quick and comfortable servicing. These ultra-high accuracy ball bearings are created to withstand all extremes within track under racing conditions and sometimes even simply fun race. A "must have" item!
