Fresh high-speed ball-bearings produced especially for XRAY. ID x OD x depth (mm) = 8x14x4. Couple of 2 pieces. Top-quality expert ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings are fitted with original plastic covers, and are also often degreased and carefully filled with special oil for optimum smoothness, longevity, greatest tolerance and optimum performance.
These ball-bearings have significantly more (and bigger) balls within the cage than the regular ball-bearings, making them even more resilient under loads. The medial side covers are really very easy to eradicate for quick and comfortable servicing. These ultra-high accuracy ball bearings are made to withstand all extremes at track under race conditions or even merely fun racing. A "must have" product!
