KMC E9, E-Bike Chain, 9 Speed, Anti-Rust

KMC E-bike chains feature high tensile strength, reinforced e-pins, and high torsion resistance to handle mid-drive motor torque. They are available across 8 to 13-speed and single-speed configurations. E9, 9 Speed E-Bike Chain, Anti-RustA strong chain designed specifically for E-Bikes and to be able to work efficiently under the stress and loads that E-bikes put on the drivetrain. EcoProteQ treatment doubles the rust resistance compared to other treatments. 1/2" X 11/128" Pin Length: 6.6 mm 122 Links Colour: Silver Hi-Performance Triple X-Durability E-Bike Non Directional Nickel Plated EcoProTeQ Anti-Rust technology Improved durability Mid-motor e-Bike 9-speed derailleur systems Weight: 316g Tool-free MissingLink master link KMC E EPT Series Features High Tensile Strength: Over 1,000 kgf capacity, exceeding standard requirements by 30% to prevent snapping under heavy power. Reinforced e-Pins: Oversized, heat-treated pin power reaching up to 450 kgf to withstand shifting under load. High Torsion Resistance: Built to handle the twisting forces of center-motor systems like Bosch, Shimano, and Yamaha. Triple X-Durability: Specialized hardening and heat treatment processes that triple the operational mileage lifespan. TechEcoProTeQ (EPT): Anti-rust coating applied to every individual link offering double the corrosion protection of standard finishes against water and salt. Non-Directional Design: Symmetrical plate structures allowing simple, independent installation orientation. X-Bridge Technology: Outer plate chamfering designed for fast, smooth gear changes.
