ACB 6805 CC - 1" Angular Contact, Black-Oxide Headset Bearing - 27.15 x 38 x 6.5mm (36 x 45 deg)

Not all variants of stainless steel are equal in quality and performance. Enduro exclusively employs 440C stainless steel balls and races, offering extended durability and superior resistance to corrosion in settings that might not be ideal. Among the standard 440-series stainless alloys with high carbon content, 440C stands out for its exceptional strength, hardness, and wear resistance. This grade, being the most expensive within the 440 series, necessitates multiple rounds of heat treatment and cryogenic processes to attain its exceptional mechanical properties. Although stainless steel has a 20% lower load capacity and is marginally softer compared to our standard 52100 chromium steel utilized in most bearings, it serves as an excellent alternative, particularly in wet conditions, frequent bike-washing scenarios, or environments prone to sweat-related issues. Additionally, Enduro Bearings incorporates LLB-type seals and CRC Marine grease into these bearings to further waterproof them against external elements. The Enduro 440C stainless headset bearings are the same as those found in numerous renowned headset brands, some of which offer an impressive 110-year warranty.

Within the Enduro line of angular-contact headset bearings, the journey begins with Chromium Steel races treated with Black Oxide, progressing to full 440C stainless steel, and reaching the pinnacle with the top-tier, lifetime-guaranteed XD-15 aerospace-stainless (comprising races and balls). These bearings are consistently crafted with the largest feasible balls, featuring dual-lip seals travelling within a micro-groove (labyrinth) and filled to 90% capacity with high-pressure waterproof grease. This meticulous engineering ensures the ultimate defence against sweat and environmental factors. Furthermore, the design of Enduro Angular Contact (A/C) bearings guarantees an even engagement of all balls, distributing force across a wider surface area to effectively reduce wear and extend the operational lifespan.
