The bicycle chain is part of the chain drive used in bicycles, which transmits the torque generated by the rider's pedaling to the drive wheel. The efficiency of a chain can be as high as 98%. In derailleur systems, the laterally shifted chain, which continues to run with low tension, moves onto a parallel sprocket or chainring. This item is specifically designed for e-bikes; it is extremely tear-resistant and has a long lifespan. The chain is compatible with Shimano and SRAM/Suntour.
