1、All parts of the chain undergo uniform heat treatment, which improves rigidity and toughness and is durable. 2、Made of high‑quality manganese steel material, high rigidity, high wear resistance, sturdiness and durability, and long service life. 3、Easy to install and remove, just use the magic buckle to connect the chain, and then turn the sprocket to confirm that the chain is firmly connected. 4、It adopts color plating process to carry out tensile test and fatigue resistance test on the chain. It is an excellent accessory for mountain bikes and road bikes. 5、Immediately shift gears with high operating acuity, quickly capture shifting actions, faster winding point, more stable running between teeth, and smoother riding.
