What some of our recent buyers are telling us about upgrading to our ceramic bearings:
Our ABEC 5 bearings feature chrome steel races which are harder and lower friction than stainless steel.
The balls are high quality Si3N4 (silicon nitride balls) and nylon cages, filled with Shell Alvania RLQ2 grease.
Rubber seals are pliable with just the right amount of preload to keep dirt out and rolling resistance low.
Kit includes sizes: 6903-2RS (3pcs), 608-2RS (1pcs) 609-2RS (1pcs) Includes freehub outer ball bearing (609-2RS); Total (5) qty bearings.
The seal color can be blue or black depending on stock. The performance is ideal for both color and the bearings can't be seen inside the hubs when istalled.
Tip on how to determine which bearings you need: The bearing number is listed on your seals, in most cases. Pull the front axle adjuster nut to verify and check the bearing number. Rear axles vary less consisting of one 6903 and one 608 bearing.
