One of the core challenges in manufacturing derailleur gears is the precise pairing of ramp and pin designs. The ramp angles and the special guiding pins directly affect the speed and smoothness of chain transitions between different chainrings.

Through precision stamping die design, we can perfectly control every ramp angle and the position of each guiding pin on the gear. This ensures the chain moves smoothly, quickly, and precisely during shifts.

This combination of high-tonnage presses and precision molds not only efficiently produces high-strength, lightweight derailleur gears but also ensures each gear meets stringent performance standards, providing riders with a superior shifting experience.
