Upgrade your bike with the ACB 3645 3544 SS 1-1/4 angular contact headset bearing, crafted from high-quality 440C stainless steel for exceptional corrosion resistance and durability. This bearing features 35mm x 44mm x 5.5mm dimensions with a 36° x 45° angle, making it a reliable choice for demanding cycling conditions. Known in the industry as AC3544 or ACB3544H5.5, it is designed specifically for enduro and mountain biking, offering long-lasting performance in wet or harsh environments.

Constructed with 440C stainless steel balls and races, this bearing provides superior strength, hardness, and wear resistance. Enduro only uses 440C in their bearings to ensure longevity and corrosion protection, especially in challenging conditions. The bearings are sealed with LLB type seals and lubricated with CRC Marine grease for enhanced waterproofing against water, mud, and debris.

All Enduro stainless steel headset bearings come with a limited lifetime warranty. The performance levels range from entry-level with Black-Oxide treated races and a two-year warranty, to premium models with full lifetime coverage. Designed with large balls and dual lip labyrinth seals, these bearings maximize protection and lifespan. The Angular Contact (A/C) design ensures load engagement across all balls, distributing force evenly and greatly extending bearing life.
