New high-speed ball-bearings produced created for XRAY. ID x OD x level (mm) = 12 x 18 x 4. couple of 2.
Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These finest quality ball-bearings are fitted with original synthetic covers, and generally are degreased and carefully oiled with AeroShell Fluid 12 oil for optimum smoothness, longevity, best limit and maximum performance. These ball-bearings have significantly more (and bigger) balls within the cage versus regular ball-bearings, making them more resilient under lots. The medial side covers are really easy to expel for fast and comfortable servicing. These ultra-high precision ball bearings are made to withstand all extremes at track under battle conditions or just fun competition. A "must have" product!
