Import Bicycle Derailleur Units — Buy in Bulk from Supplier in China

The bicycle derailleur units from Ningbo Sunrun Industry & Trade Co. Ltd. are engineered for precise gear shifting and durability in cycling applications. These components are constructed from high-strength alloys and reinforced plastics, ensuring longevity and consistent performance across road, mountain, and touring bikes. The lightweight design minimizes added weight while maintaining structural integrity under load.

Industry-standard derailleur units for bicycles typically feature a pivot system with sealed bearings to reduce friction and improve shifting accuracy. The cage length is a critical specification, with short (SS), medium (GS), and long (SGS) options available to accommodate different cassette sizes and chain lengths. Standard materials include aluminum for the cage and body, paired with steel or titanium for the spring and pivot bolts, which provide a typical tensile strength of 600-900 MPa.

These derailleur units are ideal for bicycle manufacturers, OEM assemblers, and aftermarket suppliers sourcing components for performance or utility bikes. Buyers should confirm compatibility with the drivetrain system (e.g., Shimano, SRAM, or Campagnolo) and the maximum cassette sprocket size (e.g., 28T, 32T, or 36T) supported by the derailleur. The supplier operates from Shengshan Industry Zone in Cixi, Ningbo, providing a strategic location for export logistics.
