Feature:1. High Stiffness: Bike chain reinforced shaft, the concave is embedded in a high rigidity compact structure, and the tensile strength is high. The actual test breaking force: 9537N, the ejection force: 1801N. The chain is flexible, will not be stuck, and can withstand high pedal force.2. 116 Links and Double Bridge Chain: The chain length of the 116 link provides more reserves for the subsequent upgrade of the transmission system. Double bridge chain can improve the tensile and torsional strength of the chain, and the speed change is sensitive and stable.3. Electroplating Process: The of the 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. It can withstand more wear, which means you can get more mileage.4. High Performance: 116 links 12 speed bike chain waist is chamfered design, the chain is rust proof, anti corrosion, wear resistant and durable. The tooth tips engage with the chain pieces quickly, and the stability and are greatly improved.5. Applicable Model: Bike chain is suitable for 12 36 speed models, and applicable to most mountain bikes, road bikes, folding bikes, etc. in the market. Carbon steel bike chain comes with 2 chain links, which can be installed more quickly and conveniently.Specification:Item Type: Bike ChainMaterial: Carbon SteelApplicable Model: Most Mountain Bikes, Road Bikes, Folding Bikes, etc.Applicable Speed Model: 12 36 Speed ModelsShaft Length: Approx. 5.4mm / 0.2in Package List:1 xBike Chain2 x Chain LinksNote:Please allow some errors due to manual measurement.
