Brand new high-speed ball-bearings produced particularly for XRAY. ID x OD x thickness (mm) = 6x13x5. 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, as they are degreased and lightly oiled with AeroShell Fluid 12 oil for maximum smoothness, long life, highest threshold and optimum performance.
These ball-bearings have significantly more (and bigger) balls in the cage compared to the regular ball-bearings, making them much 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 designed to withstand all extremes at the track under racing conditions or simply fun racing. A "must have" item!
