Designed for mid drive motor e-bikes, the KMC e9 Sport 9-Speed E-Bike Chain is built with increased tensile strength to exceed the international standard by over 30% so you can push even harder.
To give durability a boost, the chain undergoes special heat treatment and uses KMC's patented metal coating for rigidity, flexibility, strength, and reduced wear and tear for an estimated lifespan of 7500km (4660 miles).
