Bearing 61803 Coated

Engineered for unparalleled low friction and ultimate durability, optimizing power transfer and efficiency with enhanced protection in high-performance cycling components.

The CeramicSpeed Bearing 61803 Coated is a premium precision ceramic bearing, meticulously designed to provide the absolute pinnacle of performance and longevity for your bicycle's rotating parts. Featuring high-quality CeramicSpeed balls and robust steel races, this bearing dramatically reduces friction compared to traditional steel bearings. The "Coated" version includes an additional metallic layer applied to the races, making them 75% harder than hardened steel, significantly extending bearing life and further reducing friction, especially in corrosive environments. Its precise 17x26x5mm dimensions make it compatible with various cycling applications, offering the ultimate upgrade in ride quality and component lifespan.

• Coated races provide 75% increased hardness over hardened steel for ultimate durability and reduced friction.
• Standard CeramicSpeed balls for ultra-low friction and enhanced efficiency.
• Precise 17mm inner diameter, 26mm outer diameter, and 5mm width for specific component compatibility.
• Optimizes power transfer and minimizes mechanical drag in rotating parts.
• Ideal for upgrading hubs, bottom brackets, or other bearing-dependent cycling components where maximum performance and longevity are desired.
