Headset Bearing Enduro 6808 SS 40x51x6.5 (36x36°)

Enduro 6808 SS headset bearing is a premium angular contact bearing featuring 440C stainless steel balls and races for outstanding corrosion resistance and long-term durability in harsh conditions.

This version differs from standard 6808 bearings with a slightly smaller outer diameter and 36° / 36° chamfers, originally specified for bikes such as Trek Madone and Domane.

Enduro uses high-grade 440C stainless steel to ensure excellent strength, wear resistance, and longevity. While slightly softer than chromium steel, it is ideal for wet environments and protects against sweat and moisture.

The bearing features LLB dual-lip labyrinth seals and is filled with Almagard high-pressure grease for superior protection against dirt and water. The angular contact design distributes load evenly across all balls, reducing wear and maximizing lifespan.
