1、Sturdy Connection: Parallel riveting process tightly combines the links, making them have more durable connection mode, allowing the chain to withstand mechanical stampeding damage at high speed and rapid gearshift. 2、Light Weight, Constant Strength: Accurate design of internal and external chain hollow block structure, can reduce the overall weight with constant strength. 3、High Efficiency: High rigidity and high wear resistance can provide efficient trampling force transmission and stable energy transmission, and maintain a high force transmission rate. 4、Corresponding Guide Angle: The symmetrical guide angle of the outer plate of the chain leads the chain and the toothed disc flywheel to move more harmoniously and smoothly when the chain moves up and down, so that the speed change respond is more efficient and agile. 5、Practical Kit: It is the best choice for the pursuit of lightweight matching or long distance riding, additionally included chain plier and 2 links, able to resolve emergency problem.
