Xray 309055
T1 High-Speed Ball Bearings 10mm x 15mm x 4mm (12)

New high-speed ball-bearings manufactured specially for XRAY. Top-quality professional ball-bearings for a super-free, super-smooth drivetrain. These highest quality ball-bearings are fitted with special polyamid blue covers, and are degreased and lightly oiled with AeroShell Fluid 12 oil for maximum smoothness, long life, highest tolerance and maximum performance. <br /> <br /> <br /> These ball-bearings have more (and larger) balls inside the cage than the regular ball-bearings, making them much more resilient under loads. The blue polyamide covers are easy to remove for quick and comfortable servicing.<br /> <br /> These ultra-high precision ball bearings are designed to withstand all extremes at the track under racing conditions or even just fun racing. A \&quot;must have\&quot; item!<br /> <br /> These new high-speed bearings are substitutes for 309053 HQ Ball-Bearing 10x15x4 Blue Covered (12), as these are already degreased and oiled for higher speed.<br /> <br /> This complete set of 12 ball-bearings replaces all 10x15x4 ball-bearings on your T1.
