Replacing your dried out or pitted wheel bearings with hybrid ceramic bearings has never been more affordable!
Lower your rolling resistance compared to standard bearings. You will be surprised at the reduced rolling resistance.
Increase your pedaling efficiency compared to standard steel 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 grade 6) 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.
