Bicycle Chain Guide

1. The function of bicycle chain
The bicycle chain is a key component in transmitting pedal power to the rear wheel. It converts the rider's power into the bike's forward momentum, so keeping the chain in good condition is crucial.

2. Type of chain
• Single speed chain: Suitable for single speed bikes such as city bikes and fixed gear bikes.

• Multi-speed chain: Used on geared bicycles, the chain width and design vary depending on the gearing system.

• KMC Chain: KMC is a well-known chain brand known for its durability and high performance, suitable for all types of bicycles.

3. How to choose the right chain

• Compatibility: Make sure the chain is compatible with your bike’s shifting system. Different transmission systems (such as 8-speed, 9-speed, 10-speed, etc.) require different widths of chains.

• Material: High-quality chains are usually made from durable steel, and some are nickel-plated to prevent rust.

• Brand: Choose well-known brands such as KMC, Shimano or SRAM. The chains of these brands have reliable quality and superior performance.

4. Chain maintenance

• Cleaning: Clean the chain regularly to remove dirt and oil. Chain cleaners and special cleaners can be used.

• Lubrication: Keeps the chain lubricated to reduce wear and noise. Choose suitable lubricant, choose dry or wet lubricant according to the riding environment.

• Check for wear: Use a chain wear detection tool to regularly check the wear of the chain and replace severely worn chains in a timely manner.

5. Replace the chain

• Remove the old chain: Use the chain removal tool to remove the old chain.

• Install the new chain: Adjust the length of the new chain according to the chain length requirement, then use the chain connection tool to install it in place.

• Debugging: After installation, make sure the chain runs smoothly and the transmission system works properly.

6. Frequently asked questions and solutions

• Chain skipping teeth: It may be that the chain is worn or the transmission system is improperly adjusted. Check and adjust.

• Chain squeaking: usually due to lack of lubrication or the chain is too dirty. Clean and lubricate the chain.

• Broken chain: Check the chain for excessive wear or improper installation and replace with a new one if necessary
