If you want to improve drivetrain efficiency and component longevity, the XRAY 941016 high-speed 10x16x4 mm rubber-sealed bearings are a practical choice. Their sealed design helps keep grit and moisture out, preserving smooth operation across sessions.
These bearings use a denser array of slightly larger balls within the cage compared to typical units, which raises load capacity and reduces wear under racing loads. The factory application of AeroShell Fluid 12 aids in lowering rolling resistance.
The side covers are removable for easy servicing, so you can clean and relube bearings without specialised tools. That makes upkeep simpler whether you are at the track or running local practice.
