Amazing high-speed ball-bearings produced designed for XRAY. ID x OD x thickness (mm) = 5x9x3. Set of 2 pieces. Top-quality professional ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings are fitted with original synthetic covers, and therefore are degreased and carefully oiled with AeroShell Fluid 12 oil for maximum smoothness, longevity, best threshold and maximum performance.
These ball-bearings have more (and larger) balls inside the cage compared to the regular ball-bearings, making them more resilient under lots. The medial side covers are really easy to remove for fast and comfortable servicing. These ultra-high accuracy ball bearings are manufactured to withstand all extremes at track under competition conditions also just enjoyable rushing. A "must have actually" product!
