The bicycle chain is an essential component of the drivetrain that plays a crucial role in transferring the pedaling power of the cyclist to the wheels of the bicycle. Here is its function, its main characteristics and the associated standards:

Function :

The main function of the bicycle chain is to transfer the pedaling force exerted by the cyclist from the chainrings to the sprockets of the rear wheel. This helps propel the bike forward and move the rider forward. The chain is therefore a fundamental element of the transmission which ensures the connection between the different parts of the bicycle transmission system.

Features :

1. Materials:

Bicycle chains are typically made from steel, although some models may use lightweight alloys or special coatings to improve their performance. High-end chains may also feature hollow or perforated links to reduce weight while maintaining strength.

2. Sustainability:

Bicycle chains are subject to significant stress, including tension, twisting and wear from friction. Therefore, they are designed to be robust and durable to withstand these stresses and ensure reliable operation over many years of use.

3. Compatibility:

Bicycle chains are available in different widths and lengths to accommodate different bicycle drivetrain configurations. It is important to choose a chain compatible with the number of speeds of the bike and the type of transmission (single-speed, multi-speed, derailleur, etc.).

4. Maintenance:

To ensure optimal operation and extend the life of the chain, regular maintenance is necessary. This includes cleaning, lubricating and periodically replacing the chain when it becomes worn.


Bicycle chain standards may vary depending on the type of bicycle and the transmission system used. Some of the most common standards include:

- Chain Width: Bicycle chains are available in different widths to accommodate different drivetrain configurations, such as single-speed drivetrains, 6, 7, 8, 9, 10, 11 or 12-speed drivetrains.

- Link type: Chains can be fitted with screw, rivet or quick-release links, each with their own advantages in terms of ease of installation and maintenance.

In summary, the bicycle chain is an essential component of the drivetrain that ensures the efficient transfer of the cyclist's pedaling power to the wheels of the bicycle. It is designed to be durable, compatible and requires regular maintenance to ensure optimal operation.
