ketjuöljy

Ketjuöljy, or chain oil, is a lubricant specifically designed for bicycle chains. Its primary function is to reduce friction between the moving parts of the chain, which include the pins, rollers, and plates. By minimizing this friction, ketjuöljy helps to ensure smooth gear changes, prevent excessive wear on the chain and sprockets, and improve overall drivetrain efficiency.

There are several types of ketjuöljy available, generally categorized by their viscosity and composition. Wet lubes are thicker and more durable, designed for riding in wet or muddy conditions. They adhere well to the chain but can attract more dirt. Dry lubes are lighter and create a drier film on the chain, making them ideal for dry, dusty environments as they are less likely to pick up grit. There are also all-condition lubes that aim to provide a balance between the two. Some ketjuöljyt contain additives like Teflon or ceramic particles to further enhance lubrication and reduce wear.

Proper application of ketjuöljy is crucial for its effectiveness. The chain should be clean before application. A small amount of oil is typically applied to the rollers of the chain while rotating the pedals backward. Excess oil should then be wiped away to prevent it from attracting dirt. Regular cleaning and re-lubrication of the bicycle chain with ketjuöljy are essential maintenance practices for any cyclist.
