B 543 2RS MAX - 1 1/2" MAX-Type Headset Bearing - 1 9/16 x 2 x 9/32 inch
1-1/2 Full-Complement, Max-Type Bearing tailored for Internal Headsets boasts 52100 High-Carbon Chromium alloy races combined with grade 10 balls.
The range of Enduro headset bearings initiates with Chromium steel races treated with Black oxide, progresses to complete 440C stainless steel, and reaches the pinnacle with XD-15 aerospace-stainless races and balls, promising a lifetime guarantee. These bearings consistently integrate the largest possible balls in their design, incorporating dual-lip seals that traverse a micro-groove (labyrinth). They are filled to 90% capacity with high-pressure waterproof grease, ensuring unparalleled defence against sweat and environmental elements. The engineering of Enduro Angular Contact (A/C) bearings focuses on achieving uniform ball engagement, distributing force across a broader surface area, thereby reducing wear and extending the bearing's lifespan.
