The 6800 bearing (10x19x5mm) is one of the most common individual hub bearings across road cycling. Our Grade 3 silicon nitride ceramic version replaces a single steel bearing with a unit that's harder, smoother, and more corrosion-resistant. ABEC-7 tolerances ensure precise fit. Order the quantity you need — most hubs require 2 per position.
