Bike Headset Bearings- All Sizes - Blueseal Bike Bearings™
ABEC 3 as Standard
Most non-bike specific bearings are ABEC 1 as standard. Blueseal Bike Bearings™ are all ABEC 3 Rated, this higher class of bearing runs smoother & last longer.
Max. Fill Premium Grease
Standard bearings contain a small amount of basic bearing grease (Approx. 20%) which offers little protection towards corrosion and rain and dirt ingress.
Blueseal Bike Bearings™ contain the maximum fill of Mobil waterproof grease possible without compromising the function of the close-contact rubber seals.
Designed For Bicycles
Specially engineered bicycle bearings. Designed for maximum efficiency, they outperform standard bearings.
Close Contact 2RS LLU Seals
Blueseal Bike Bearings™ have top-quality LLU 2RS close-contact rubber seals. The tighter the seal is to the inner bearing race the harder for water and dirt to get in and the grease to get out!
