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.
