Material: chromium-molybdenum steel, high strength, super tensile strength, enhanced axle embedding force, high temperature resistance (each part to heat treatment processing, strengthening rigidity and toughness), low friction, no noise, smooth shifting, light weight. Smooth shifting, no noise.

Process: Vacuum electroplating process, full electroplating surface layer, the chain has been tested by tensile force, the tensile strength of 1050kgf, the ultimate tensile load 31.1 (KN), fatigue resistance test, quality assurance.

In the shift angle, the interference of the gear tip to the chain is reduced, which greatly reduces noise and friction.

The double X-bridge design makes the shifting smoother, and the same bridge and chamfer design on both sides of the chain saves the installation directionality and increases the convenience of installation.

Multi-layer composite structure plating with advanced GLC technology enhances the HV hardness of the pin surface and improves the surface roughness RA0.15um: better lubrication performance, wear resistance and transmission efficiency can be achieved, improving riding experience and chain life.

Before riding the bicycle with the chain, the connection portion must be in good condition

to avoid coming off . In normal utilization , the chain shall be oiled in every 100KM riding and it shall be maintained in every 300KM riding, if riding in bad environment, it is strongly suggested to do maintenance in every 200KM riding. if no utilization in long time , before riding, a lubricant shall be applied on the chain and let the chain to move several cycles when downloading or disassembly a set of chain, it is a must to use special chain assembly/disassembly tool, it is forbidden to repeat the connecting with the same connector pin.
