Brand-new high-speed ball-bearings manufactured specially for XRAY. ID x OD x level (mm) = 5x8x2.5mm. Group of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings are fitted with exclusive synthetic covers, and so are degreased and gently oiled with AeroShell Fluid 12 oil for maximum smoothness, long life, best limit and maximum performance.
These ball-bearings do have more (and larger) balls in the cage when compared with regular ball-bearings, making them more resilient under lots. The medial side covers are actually a simple task to get rid of for fast and comfortable servicing. These ultra-high accuracy ball bearings are made to withstand all extremes at track under battle conditions and sometimes even just fun battle. A "must have" item!
