It combines chromium steel races from Enduro's ABEC 5 range with Grade 5 ceramic balls made of Silicon Nitride (Si3n4). This mix results in a ceramic bearing that is lighter, more efficient, and cost effective, making it ideal for hubs and bottom brackets. The low contact LLB seals ensure protection against water and dirt without adding friction. Bearing Code:
