Rex Wax

Black Diamond Bearing Oil - 1.0oz

Rex Wax Black Diamond Bearing Oil is a purpose-built, low-viscosity lubricant for fast-spinning bicycle bearings where heavy grease can add drag. Packaged in a precise 1.0oz bottle, it targets the small bearing systems found in hubs, derailleur pulley wheels, and other rotating bearing applications—helping maintain smooth rotation and reduce wear under regular service intervals.

• Bearing-specific oil weight - Designed for spinning bearing applications where minimizing friction and resisting “sticky” feel matters
• Hub and pulley-ready - Well-suited for common service points like hub bearings and derailleur pulley wheel bearings
• Ceramic and steel compatibility - Safe for both ceramic and traditional bearing systems for broad workshop and rider use
• 1.0oz size - Practical quantity for routine maintenance without committing to a large bottle
