Brand new high-speed ball-bearings manufactured particularly for XRAY. ID x OD x depth (mm) = 5x8x2.5mm. Set of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These best quality ball-bearings are fitted with original synthetic covers, and so are degreased and gently oiled with AeroShell Fluid 12 oil for optimum smoothness, long life, greatest threshold and maximum performance.
These ball-bearings have significantly more (and larger) balls in the cage compared to regular ball-bearings, making them more resilient under lots. The medial side covers are actually an easy task to remove for fast and comfortable servicing. These ultra-high precision ball bearings are made to withstand all extremes at track under race conditions or even just fun race. A "must have" item!
