ENDURO BEARINGS CERAMIC HYBRID - High-performance ceramic balls / steel rings.

• Grade 5 silicon nitride ceramic balls
• Double-lip labyrinth seals for excellent resistance to water and dust.

“Ceramic Hybrid” and “Zero Ceramic BO” ceramic bearings deliver optimal performance when they are properly maintained.

 These bearings must be serviced every six months by a professional mechanic (watch the video). Failure to follow this instruction will void the warranty. Proper bearing maintenance involves thoroughly cleaning them and re-greasing them with Enduro XD15 Speed Grease (part no. GR-011).
