ENDURO BEARINGS Acb 3645 cc sxd - xd-15 ceramic (angular contact) - 30,2x41x6,5 (36x45°)

Upgrade your bike with the high-performance ACB 3645 CC SXD internal headset bearing, designed with XD-15 races and balls to ensure lifetime corrosion resistance. This durable bearing is the ultimate choice for demanding cycling conditions, offering unmatched longevity and reliability. Inspired by recent Enduro developments, these full XD-15 bearings deliver performance and corrosion resistance comparable to ceramic-hybrid bearings used in hubs and bottom brackets, but with enhanced impact resistance thanks to stainless steel balls. Enduro testing in saltwater environments for months confirms that these bearings resist corrosion better than any on the market. We are so confident in this material that we guarantee these bearings for life against corrosion. This size is also recognized in the cycling industry under part numbers: 27287-1046-004, HSS0130K, TH-873E, MR-122. Our Enduro line offers two performance levels: the entry-level bearings with premium Black-Oxide races and a two-year warranty, and the premium 440C stainless steel bearings with a lifetime warranty. All bearings feature large balls and dual-lip labyrinth seals for maximum protection against dirt, water, and sweat, ensuring smooth operation over time. The angular contact design allows all balls to engage load evenly, spreading force across a larger surface for extended bearing life. Specifications:

• Static load: 935 lbf / 4.15 kN
• Weight: 19.2 g
