Why choose Blueseal Bike Bearings™

Blueseal Bike Bearings™ are bike specific bearings, designed by bikers who understand what is required to endure adverse biking conditions. The only bearing to use in bicycle headsets.

High Quality & Low Friction Close Contact Seals - Keeps the muck out and the grease in.

Max. Fill of Mobil XHP 222 Waterproof Grease - Premium grease with the highest wash out resistance.

Highest Quality - Strong composition and super smooth.

Bearing Seal Design

All Blueseal Bike Bearings™ posses top quality close contact rubber seals. The tighter the seal is to the bearing race the harder for water and dirt to get in and the grease to get out! This is the most important feature for a bike bearing.

Highest Quality

Blueseal Bike Bearings™ are made from the highest quality materials, this higher class of bearing run smoother & last longer. 

Premium Bearing Grease

Blueseal Bike Bearings™ contain the maximum fill of Mobil XHP 222 grease possible without compromising the function of the close contact rubber seals.

Mobil XHP 222 is a marine specific grease that boasts high wash out resistance and is designed for use in wet & dry conditions. This means the grease stays in the bearing for longer and offers the best protection against dirt, rain and muddy water.

Standard stock bearings are designed for use in machinery and contain very little amounts of non specific bearing grease (Approx. 20%) This offers little protection against rain and dirt ingress.
