KMC E12, E-Bike Chain, 12 Speed, Anti-Rust

KMC E, 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. 

E12, 12 Speed E-Bike Chain 
A 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. The E-Series was developed with extra safety reserves for E-Bikes, but is still a perfect choice for classic bikes. This 12 speed chain comes with the highly effective EPT anti-rust coating for added endurance and protection.

KMC E 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 centre-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.
