  The Mechanism and Maintenance of Bicycle Chain Lubricant

Chain Components and Their Functions


Bicycle chains are comprised of several interconnected metal links that form a continuous loop around the chain rings at the front and rear cassette at the back. The inner links have hollow spaces that fit over pins connecting each outer link. At the core is a row of tightly packed bushings and rollers that allow the chain to smoothly rotate under pedaling power.


The outer chain links are what can be seen when looking at the moving chain. They alternate between inner links that have hollow spaces and outer links that are solid with protruding pins. The pins fit into holes in the inner links to connect each outer link and allow the chain to flex as it wraps around gears.


Situated inside the outer links of a Bicycle Chain Lubricant are bushings and cylindrical rollers. The rollers are the components that actually come into contact with the chain rings and cassette sprockets, as they rotate the chain around the gears. The bushings separate each roller and help reduce friction, allowing for efficient power transfer from the pedals to the rear wheel.


Proper Chain Maintenance Ensures Smooth Operation


The chain on a bicycle constantly flexes and bends around gears while supporting the rider's pedaling forces, which means it requires regular care and maintenance to maximize its lifespan. Over time, dirt, grime, and lubricant breakdown can accumulate inside the chain links if not addressed. This buildup leads to increased friction, noisy operation, and accelerated wear of the components.


Cleaning the chain is the first important maintenance task. It should be done frequently, especially after riding in wet or dusty conditions. Use a degreasing bike cleaner and spray it directly onto the chain while rotating the cranks. Let it soak in, then wipe away the residue using an old toothbrush or rag.


Proper lubrication after cleaning is also essential. Choose a bike-specific chain oil or wax-based lubricant and apply it to the inner links. Spin the cranks slowly while adding a few drops at a time so the lubricant penetrates deep inside. Be sure to wipe away any excess to prevent dirt buildup. Lubricate the chain every few rides or after cleaning.


In addition to cleaning and lubricating, it’s important to check the chain’s wear regularly. This allows for timely chain replacement before additional damage occurs. Use a chain wear indicator tool, which slides into the links. If the tool no longer fits tightly, the chain has stretched beyond its usable lifespan and needs replacement. Always replace the chain in conjunction with the front chain rings and rear cassette to ensure proper gear meshing.


Other Simple Maintenance Tips


A few other simple maintenance tasks can be performed on the chain to extend its service life:


- Check tightness of the connecting chain pin and tighten if loose with a chain tool.


- Inspect gears for sharp edges or burrs that could be cutting into chain links over time. Use sandpaper as needed.


- Adjust derailleur tension if the chain is skipping gears or coming off tracks easily. The rear derailleur should be parallel to the cassette.


- Clean and re-lubricate the chain after riding in wet conditions to prevent rusting inside links.


- Consider upgrading to a chain love or chain stay guard to protect the chain from debris flung from the road on commuter bikes.


With the proper maintenance regimen, a bicycle chain can typically last hundreds or even thousands of miles before requiring replacement. Following the steps above ensures the chain runs smoothly across multiple components for durable performance ride after ride.
