New high-speed ball-bearings manufactured specially for XRAY. ID x OD x thickness (mm) = 12 x 18 x 4. Set of 2.

Top-quality professional ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings
are fitted with special rubber covers, and are degreased and lightly oiled with AeroShell Fluid 12 oil for maximum smoothness,
long life, highest tolerance and maximum performance.

These ball-bearings have more (and larger) balls inside the cage than the regular ball-bearings,
making them much more resilient under loads. The side covers are easy to remove for quick and comfortable servicing.

These ultra-high precision ball bearings are designed to withstand all extremes at the track under racing conditions
or even just fun racing. A "must have" item!
