Features1[High Stiffness] The chain shaft is reinforced and the concave surface is embedded in a high stiffness compact structure, with high tensile strength, flexible chain and shifting. 2[116 Link] The chain length of 116 links provides more reserve for subsequent upgrade bike of the transmission system and can withstand high pedal force. 3[Double Bridge type] Double bridge type chain can improve the chain's tensile and torsional strength, and the speed change is sensitive without jamming. 4[High Performance] The waist of the bike chain is chamfer design , and the tooth tip engages with the chain piece quickly, so the stability and safety are greatly improved. 5[Electroplating Process] The chain surface, inner and outer plates and pins are treated by electroplating process, which is not easy to rust and the chain is hard and durable.SpecificationItem Type: Bike ChainMaterial: Carbon SteelAxial Length: Approx. 5.8mm/0.2inSuitable Model: most Mountain Bikes, Road Bikes, Folding Bikes, etcSuitable for Different Speed Models: 11 33 Speed ModelsPulling Force: 9537NEjecting Force:1801NPackage List1 x 11 Speed Bike Chain2 x Hook and loop
