New high-speed ball-bearings manufactured particularly for XRAY. ID x OD x depth (mm) = 5x8x2.5mm. Set of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These finest quality ball-bearings are fitted with unique plastic covers, and therefore are degreased and gently oiled with AeroShell Fluid 12 oil for optimum smoothness, long life, greatest threshold and optimum performance.
These ball-bearings have significantly more (and bigger) balls in the cage compared to regular ball-bearings, making them far more resilient under loads. The medial side covers are really easy to remove for fast and comfortable servicing. These ultra-high accuracy ball bearings are designed to withstand all extremes at the track under racing conditions and on occasion even just fun racing. A "must have" item!
