KMC E11, E-Bike Chain, 11 Speed, Anti-Rust

KMC E11, 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. 

E11, 11 Speed E-Bike Chain 
11x E-Bike chain specially designed for middle engine driven e-bikes such as Bosch, Panasonic and AEG, these chains have higher torsion resistance to cope with ruthless shifting and hi-torques. The KMC E-series chains for derailleur and hub gears are extremely resilient and offer an unrivalled service life. EcoProteQ treatment doubles the rust resistance compared to other treatments.
