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 deveoloped with extra safety reserves for E-Bikes, but is still a perfect choice for classic bikes. This 11 speed chain comes with the highly effective EPT anti-rust coating for added endurance and protection.**EPT Coating**The environmentally friendly EcoProTeQ technology EPT from KMC protects chains against corrosion for twice as long as conventional rust protection, setting a new standard. Each component of every chain link is treated separately with EPT. This means a 100% coating that offers the lowest possible attack by water, salt, and air humidity.Another characteristic of EPT: The very smooth surface gives chains excellent running qualities. Dirt buildup is minimised in the long term, which means that chain maintenance is significantly relieved.* 1/2" X 11/128"* Pin Length: 5.65 mm* Colour: Dark Silver* Hi-Performance* Triple X-Durability* Anti Rust/e-Bike* Non Directional* Weight: 305g per 110 links* EcoProTeQ coated* Mid-motor e-Bike 11-speed derailleur systems
