XRAY 941319 High-Speed Ball-Bearing 13x19x4 Rubber Sealed 2 Rubber Sealed Bearings
Groundbreaking high-speed ball-bearings produced particularly for XRAY. ID x OD x level (mm) = 13x19x4. Couple of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These affordable ball-bearings are fitted with unique artificial covers, and perhaps they are degreased and gently full of unique oil for optimum smoothness, endurance, best threshold and maximum performance.
These ball-bearings do have more (and bigger) balls into the cage compared to the regular ball-bearings, making them far more resilient under lots. The medial component covers are now actually a simple task to get rid of for fast and comfortable servicing. These ultra-high accuracy ball bearings are manufactured to withstand all extremes through the complete track under battle conditions and even just fun battle. A "must have actually" item!
