Item Type: Bike Chain_x000D_ Material: Carbon Steel_x000D_ Shaft Length: Approx. 5.7mm/0.22in_x000D_ Applicable Models: Most Mountain Bikes, Road Bikes, Folding Bikes, etc_x000D_ Applicable Speed Models: 11, 33 Speed Models 1[High Strength] Bike chain has high tensile strength, reinforced shaft, with concave embedded high rigidity compact structure, suitable for mountain bikes, road bikes, folding bikes, etc. 2[Strength Detection] Actual detection of 11 speed chain breaking force: 9537N, ejection force: 1801N, the chain is flexible, will not be stuck, and can withstand high pedal force. Can be used for a long time. 3[Easy To Use] Chain length of 116 links provides more reserves for subsequent upgrades of the transmission system. Double bridge chain, tensile and torsion resistant, sensitive and stable speed changes. 4[High Performance] The waist of the bike chain is chamfered, which is anti rust, anti corrosion, wearable and durable. The tooth tips engage with the chain piece quickly, which is more stable and safe. 5[Electroplating Process] Surface of the bike chain is treated by electroplating process, which is not easy to rust, and the speed is stable. The inner and outer plates and pins are electroplated.1 x Bike Chain 2 x Chain Connector Manual measurement, please allow some errors.
