• 1. Precise positioning of transmission components: It can firmly fix the rear derailleur, ensuring that it maintains the optimal transmission position with the flywheel and chain, avoiding rear shift deviation caused by riding bumps, reducing transmission lag and chain drop problems, and improving shifting smoothness.
• 2. Protecting the frame and rear derailleur: As a buffer transition structure, it can disperse the force on the rear derailleur, especially during off-road bumps or accidental drops, reducing the impact on the rear fork of the frame (especially the carbon fiber frame), while reducing the probability of direct damage to the rear derailleur.
• 3. Strong adaptability and easy replacement: Different specifications of hangers can be matched with multiple vehicle models and rear shift models. If the hanger is worn or damaged, there is no need to replace the frame. The hanger can be replaced separately, with low maintenance costs and easy installation and disassembly, without the need for complex tools.
• 4. Maintain the accuracy of the transmission system: In long-term use, if there is slight deformation in the frame or rear derailleur, the transmission alignment can be corrected by adjusting the position of the suspension bracket to ensure the meshing accuracy of the chain with the flywheel and toothed disc, reduce component wear, and extend the service life.
• 5. Simplify frame design: No need to directly process complex fixed structures on the rear fork of the frame, reducing the difficulty of frame manufacturing, while making the structure of the rear fork of the frame simpler, without affecting the overall strength and lightweight design of the frame, suitable for more mountain bikes and road bike models.
