Description

Detailed Specifications: Use : The lock nut is used in the bottom bracket assembly of a bicycle to secure the bottom bracket shell. It is typically employed in threaded bottom brackets, where it holds the adjustable cup in place and ensures the bottom bracket doesn’t loosen during use. This ensures consistent, smooth pedaling and reduces wear on the crankset and spindle. Material : Made from steel , which offers durability, strength, and resistance to wear under pressure from regular riding. Steel is chosen for its long-lasting properties and ability to handle the stress of continuous pedaling. Color : Chrome finish, which provides a shiny, polished appearance. Chrome not only enhances the aesthetic of the bike but also offers a layer of protection against rust and corrosion, particularly important for components exposed to moisture and dirt. Brand : AltaLine , a brand recognized for high-quality bicycle parts, especially in the custom and vintage cycling community. AltaLine offers components that cater to both restoration projects and modern custom builds. Additional Information: Compatibility : The bottom bracket lock nut is compatible with bicycles that use traditional bottom bracket systems with adjustable cups. It fits most threaded bottom bracket shells, especially in older models or classic bike designs. Function : The lock nut works in tandem with the bottom bracket spindle and cups to maintain proper alignment and secure the assembly. This prevents loosening due to vibrations, pedaling forces, or uneven surfaces. The Bottom Bracket Lock Nut Chrome is compatible with bikes that use a threaded bottom bracket system .
