The KMC e9 is a 9 speed e-bike chain with 136 links, specially designed for mid-motor e-bikes. It offers tensile strength of over 1000kgf, exceeding international standards by over 30%.
Mid-drive motors put tremendous force through the chain, and a standard 9 speed chain wears quickly under that load. The e9 gives you the strength and length an e-bike needs.
Huge tensile strength
Over 1000kgf of tensile strength handles the extra force of e-bike motors with confidence.
Leading pin power
KMC’s patented riveting system achieves 450kgf of pin power for difficult shifting situations.
Extra long
136 links gives plenty of length for e-bikes and longer frames.
Hi-torsion resistance
Extra stretch proof mushroomed pins and Triple X treatment help it hold its length.
