How durable and performant is this bicycle rear derailleur?

This bicycle rear derailleur uses steel as the main material, which is widely used in bicycle accessories due to its high strength, wear resistance and corrosion resistance. This material choice helps improve the overall durability of the rear derailleur, enabling it to maintain stable performance under various riding conditions.
Although the specific structural design is not mentioned in the problem description, in general, high-quality bicycle rear derailleurs will use a sturdy frame and optimized pulley design to reduce wear and failure. This design helps extend the service life of the rear derailleur.
The gear capacity reaches 35 tons, indicating that this rear derailleur is compatible with a wide range of gear combinations to adapt to different riding needs. The 75mm pulley distance helps ensure the stability and smoothness of the chain during the speed change process, reducing wear caused by chain deviation or jitter.
One of the main functions of the rear derailleur is to ensure that the chain can accurately switch between different gears. Through its precision design and manufacturing process, this rear derailleur is designed to provide a fast and accurate speed change experience, allowing riders to easily adjust the gear ratio according to different road conditions and riding needs.
In addition to speed change accuracy, the smoothness of the rear derailleur is also one of the important indicators to measure its performance. Smooth speed change can reduce the rider's physical exertion and improve riding comfort and efficiency. This rear derailleur is designed to achieve a smooth speed change experience by optimizing the pulley design and adjustment mechanism.
