An open-end wrench is a handy tool used in many mechanical applications, including bicycle maintenance. It is a manual wrench that has a jaw opening at both ends of the handle. This allows the user to grip a bolt or nut from two sides and turn it to loosen or tighten it.
In the context of bicycles, an open-end wrench is often used to assemble or disassemble certain parts such as the pedals, crank or axle nuts. Some bicycle components may require special open-end wrenches with specific jaw opening sizes to ensure a secure grip and prevent damage.
Open-end wrenches come in a variety of sizes and styles to meet different needs. They are an essential tool for bike mechanics and enthusiasts who perform their own bike repairs and maintenance. With a suitable open-end wrench, bike parts can be safely assembled and maintained to ensure the performance and safety of the bike.
