The chain of a freestyle dirt BMX plays a vital role in transmitting the rider's pedaling power to the wheels of the bicycle, while providing strength and durability suited to the specific conditions encountered when riding freestyle dirt. Here is its function and main characteristics:

Function :

The main function of the chain on a freestyle dirt BMX is to transfer the rider's pedaling force from the bottom bracket chainrings to the rear wheel sprockets, thereby propelling the bike forward. In the context of freestyle dirt, the chain is subjected to significant stress during jumps, tricks, hard landings and impacts on ramps and dirt bumps.

Features :

1. Sustainability:

Freestyle dirt BMXs are used in rough terrain and are subject to intense stress, particularly during hard landings and repeated impacts on obstacles. Therefore, the chain of a freestyle dirt BMX is manufactured with high quality materials and special treatments to provide increased durability and resistance to wear, impact and high stress.

2. Robustness:

BMX freestyle dirt chains are reinforced to withstand the significant stress experienced during jumps and tricks on dirt ramps and bumps. They are designed to prevent breakage or derailment, even in extreme conditions.

3. Compatibility:

BMX freestyle dirt chains are compatible with specific BMX drivetrain configurations, which can vary depending on the number of gears and the type of crankset used. It is important to choose a chain compatible with the transmission system of your BMX for optimal operation.

4. Width:

Freestyle dirt BMXs can be equipped with single speed drivetrains. Therefore, the chain width may vary depending on the type of crankset used. It is essential to choose a chain of appropriate width to ensure correct engagement with the sprockets.

5. Maintenance:

Like all moving parts of a bicycle, the chain requires regular maintenance to ensure optimal operation. This includes cleaning, lubrication and periodic replacement to prevent excessive wear and extend the life of the transmission.

In summary, the chain of a freestyle dirt BMX is an essential component that offers durability, robustness and compatibility with the tricks and jumps performed when practicing dirt freestyle. It ensures efficient transmission of the cyclist's pedaling power to the bicycle wheels, while providing increased resistance to shock and wear.
