Material Upgrades

Black Oxide Coating

  • Enhanced Corrosion Resistance: Black oxide provides a protective layer that helps prevent rust and oxidation, which can extend the life of the part, especially in humid or corrosive environments.

  • Reduced Wear: The coating reduces friction between metal surfaces, which minimizes wear and tear. This is particularly important for bearings, as they are subjected to constant motion and load.

  • Improved Durability: By forming a stable layer on the surface of the metal, black oxide increases the part's resistance to fatigue and mechanical damage.

  • Reduced Service Time Less likely to fuse to the frame and headset housing allowing for easy replacement when the time comes.

Stainless Steel

  • High Chromium Content (16-18%): The chromium forms a protective layer, making the material highly resistant to rust, corrosion, and oxidation.

  • Corrosion Resistance in Wet Conditions: 440C stainless steel performs particularly well in poor, wet, or marine conditions, where moisture can cause rust in less resistant materials.

  • High Hardness: After heat treatment, 440C can reach a high level of hardness (Rockwell hardness in the upper 50s to low 60s), making it suitable for applications requiring wear resistance.

  • Reduced Service Time Less likely to fuse to the frame and headset housing allowing for easy replacement when the time comes.

About Blueseal Bike Bearings™   

Stumpjumper Headset Bearings - Specialized - Trailvision - Bicycle Bearing Suppliers

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 LLB Seals

Blueseal Bike Bearings™ have top-quality LLB 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!

Smooth turnaround for new headset bearings

The guys from Trailvision got my new headset bearing for my Giant Trance to me quickly in smart recyclable packaging. Happy to support an independent business at this tricky time. I’ll definitely be using them again. Thanks
