Brand new high-speed ball-bearings produced especially for XRAY. ID x OD x depth (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 synthetic covers, and they are degreased and gently full of unique oil for optimum smoothness, stamina, most readily useful threshold and maximum performance.
These ball-bearings have significantly more (and larger) balls inside the cage compared to the regular ball-bearings, making them a lot more resilient under lots. The medial part covers are actually an easy task to remove for fast and comfortable servicing. These ultra-high accuracy ball bearings are manufactured to withstand all extremes through the entire track under battle conditions and on occasion even simply fun battle. A "must have" product!
