• Double X-Bridge Design: This bicycle chain adopts a double X-bridge design, which can effectively reduce the interference between the sprocket teeth and the chain during shifting, reduce the noise and friction resistance caused by component friction and collision, and enhance the overall pleasure of riding.
• Corresponding Guide Angle: The symmetrical guide angle of this bicycle chain outer plate has been carefully designed to ensure a smoother and more harmonious connection between the chain, sprocket, and flywheel during gear shifting, which helps to accelerate the gear shifting response speed.
• High Sales Riveting Relay: This bicycle chain adopts parallel riveting technology to tightly combine the various links of the chain, giving the chain strong load-bearing capacity and forming an extremely sturdy connection structure, ensuring the safety of riding.
• Long Term Use: This bicycle chain has high rigidity and wear resistance, which can efficiently transmit the rider's pedaling force, achieve stable power transmission, give the rider an advantage in the starting stage, and always maintain high transmission efficiency.
• Lightweight: The inner and outer links of this bicycle chain are designed with hollow structures, effectively reducing the overall weight while ensuring the strength of the chain. The design of the mud discharge hole can also timely discharge the mud on the chain during cycling, reducing the impact of mud on the performance of the chain.
