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