Groundbreaking high-speed ball-bearings produced specifically for XRAY. ID x OD x depth (mm) = 6x13x5. Band of 2 pieces. Top-quality specialist ball-bearings for a super-free, super-smooth drivetrain. These finest quality ball-bearings are fitted with unique artificial covers, as they are degreased and gently oiled with AeroShell Fluid 12 oil for maximum smoothness, stamina, greatest limit and maximum performance.
These ball-bearings do have more (and bigger) balls in to the cage set alongside the regular ball-bearings, making them significantly more resilient under lots. The medial component covers are now an easy task to eliminate for fast and comfortable servicing. These ultra-high precision ball bearings are created to withstand all extremes through the entire track under competition conditions or just enjoyable rushing. A "must have actually" item!
