Crafted from high-grade 440C stainless steel, this bearing offers superior corrosion resistance and long-lasting strength, making it ideal for riders who demand reliability in challenging conditions. With dimensions of 40mm x 51.8mm x 7mm and a 45° contact angle, it perfectly fits DEDA\/FSA ICR headset systems, ensuring smooth steering and enhanced control.\u003c\/p\u003e\n\n\u003cp\u003eUnlike standard stainless steel bearings, Enduro uses only 440C stainless steel balls and races, which undergo rigorous heat and cryogenic treatments to maximize hardness and wear resistance. This high-carbon alloy provides a premium balance of strength and corrosion protection, especially beneficial in wet environments or for cyclists who frequently wash their bikes. Additionally, the bearing features LLB type seals combined with CRC Marine Grease, offering outstanding waterproofing to safeguard against sweat and the elements.\u003c\/p\u003e\n\n\u003cp\u003eEnduro’s angular contact bearings are designed to distribute forces evenly across all balls, reducing friction and wear while extending bearing life. The inclusion of large balls, dual-lip seals riding in micro-grooves, and high-pressure grease filling ensures optimal protection and performance. These bearings are trusted in many renowned headset brands and come with a reputation for longevity and reliability, making them a smart upgrade for any steering system.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It’s Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eProviding smooth and precise steering control in demanding riding conditions\u003c\/li\u003e\n  \u003cli\u003eResisting corrosion and wear in wet or humid environments\u003c\/li\u003e\n  \u003cli\u003eFitting DEDA\/FSA ICR headset systems for easy and reliable replacement\u003c\/li\u003e\n  \u003cli\u003eWithstanding heavy use thanks to high-quality 440C stainless steel construction\u003c\/li\u003e\n  \u003cli\u003eOffering long service life with low maintenance due to advanced sealing and lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat It’s NOT Good For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eApplications requiring higher load capacities beyond stainless steel limits\u003c\/li\u003e\n  \u003cli\u003eHeadset systems incompatible with 40x51.8x7mm bearing dimensions\u003c\/li\u003e\n  \u003cli\u003eSituations where extreme hardness of 52100 chromium steel is mandatory\u003c\/li\u003e\n  \u003cli\u003eRiders seeking bearings without any maintenance or lubrication needs\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWill this bearing fit my headset?\u003c\/strong\u003e\u003cbr\u003eThe ACB 4545 150M is specifically designed to fit DEDA\/FSA ICR headset systems with dimensions of 40mm inner diameter, 51.8mm outer diameter, and 7mm width.
