👉 Bike fluid, often referred to as chain lubricant or derailleur fluid, is a specialized lubricant used to keep the mechanical components of a bicycle's drivetrain in optimal condition. It is typically applied to the chain, cassette, and derailleurs to reduce friction and wear, ensuring smooth and efficient gear shifting. This fluid forms a protective layer over metal parts, preventing rust and corrosion while also minimizing the noise caused by grinding or clanking. Regular application of bike fluid is crucial for maintaining the longevity and performance of a bicycle, particularly in environments with high humidity or frequent use.
