Product Dimensions: 20*10cm
Product Color: Black
Product Material: Alloy
Description:
1. Multi-gear shifting for various road conditions: The rear derailleur provides multiple gear options by guiding the chain between different sized sprockets. Riders can choose the most suitable gear ratio based on terrain (e.g., uphill, flat, downhill) and their physical condition, thereby improving pedaling efficiency and saving energy.
2. Relatively simple structure and easy maintenance: The mechanical structure of modern rear derailleurs (such as parallelogram mechanisms) is very mature and reliable. This means that daily cleaning, lubrication, and basic adjustments (such as limit screws and tension fine-tuning) can be done by the user, resulting in relatively low maintenance costs.
3. High transmission efficiency: When the chain is correctly aligned with the sprockets and precisely adjusted, the rear derailleur system has very high transmission efficiency and minimal power loss. The direct engagement ensures that power is effectively transmitted from the chainring to the rear wheel.
4. Lightweight Design
Rear derailleurs can be made very lightweight while maintaining strength and precision, contributing to a reduction in the overall bike weight—a significant advantage for performance-oriented riders.
5. Mature Technology, Abundant Options, and Good Compatibility
After decades of development, rear derailleur technology is highly mature. It can meet the needs of different bike models, budgets, and riding styles, and offers excellent compatibility with shifters and other gear components from the same brand.
Package: 1 derailleur
