2RS: Literally means the bearing has Two Rubber Seals. There are many types of seals. On most other bearings 2RS means that the seal is made from rubber and has one sealing lip rubbing on any flat part of the inner race. Enduro’s seals are usually either LLU (usually the MAX type bearings) or LLB (better for hubs).

Mobile HP 222: This grease is another high pressure grease for maximum protection and constant lubrication. This synthetic grease holds up under all conditions and will not break down.
