Groundbreaking high-speed ball-bearings produced specially 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 synthetic covers, as they are degreased and gently oiled with AeroShell Fluid 12 oil for optimum smoothness, endurance, highest limit and maximum performance.
These ball-bearings do have more (and larger) balls into the cage set alongside the regular ball-bearings, making them significantly more resilient under lots. The medial component covers are now actually an easy task to get rid of for quick and comfortable servicing. These ultra-high accuracy ball bearings are created to withstand all extremes throughout the track under competition conditions or simply fun rushing. A "must have" product!
