Enduro 686 LLB Zero Ceramic Bearings

Like Ceramic Hybrid, Zero Ceramic use a combination of ceramic (Silicon Nitride - Si3n4) balls and steel races, except they are of higher Grade 3 quality. The races are also black oxide treated and ground toa mirror finish which prevents corrosion and provides near perfect efficiency and tolerances.

Bearings Seals

LLB Seals

Enduro's most popular light contact seal. LLB seals are comprised of Nitrile material rubber with a steel insert and ideally suited for constantly spinning bottom bracket and hub bearings. Rather than one thick 2RS seal lip rubbing on a blunt surface, LLB type utilizes two razor thin sealing lips riding in the bearing race groove. The outer lip keeps the water and contaminants out, while the inner lip retains grease for smooth function and longer intervals between servicing.
