Bike Chain Compatible with 9 Speed Road Mountain Folding Bikes, 116 Links Rust Proof Electroplated

Product Details ① Reinforced Shaft & Compact Structure: Equipped with a reinforced shaft and embedded concave surface in a high-rigidity compact structure, the bike chain delivers high tensile strength, ensuring long-term use without deformation or breakage. ② Durable Chain Performance: 9-speed chain with actual detection results: breaking force 9537N, ejection force 1801N. Flexible and non-sticky, it withstands large pedaling forces, minimizing chain breakage risks during intense riding. ③ Flexible & Stable Transmission: 116-link chain length is designed to facilitate future upgrades of the transmission system. Double-bridge type construction resists tension and torsion, ensuring sensitive and stable gear shifting for smooth riding. ④ Anti-Rust & Wear-Resistant: The 9-speed chain has a chamfered waist, offering anti-rust, anti-corrosion, and wear-resistant properties. Quick engagement of tooth tips with chain links enhances stability and safety during use. ⑤ Electroplating Surface Treatment: The bike chain’s inner and outer plates and pins undergo electroplating process, reducing rust risk and ensuring consistent gear shifting performance over time. Specifications ① Item Type: Bike Chain ② Material: Carbon Steel ③ Shaft Length: Approximately 6.6mm (0.26in) ④ Compatible with Most Mountain Bikes, Road Bikes, Folding Bikes, etc ⑤ Applicable Speed Models: 9-speed and 27-speed models Packing List ① 1 x Bike Chain ② 2 x Chain Connectors Warm Tips ① Before installation, confirm the bike chain is compatible with your bike’s transmission system and applicable speed model. ② Regularly clean and lubricate the chain to maintain its performance, especially after exposure to moisture or dirt. ③ Store the chain in a dry place to prevent rust, especially if not in use for an extended period.
