The SunRace CNM9E 9-speed E-Bike chain is a reinforced drivetrain chain specifically designed for electric bicycles with mid- or hub-motor assistance. It is engineered to withstand higher torque loads and frequent shifting under pressure, making it more durable than standard 9-speed chains.

Built with high-strength steel plates and chromized pins, the CNM9E ensures reliable power transfer, smooth shifting, and extended service life even under demanding e-bike conditions. Its reinforced construction helps resist stretching, wear, and contamination from dust and dirt.

This chain is fully compatible with all standard 9-speed drivetrain systems and is suitable for MTB, trekking, city, gravel, and e-bike applications. It typically comes with a 138-link length and includes a connector link for easier installation and maintenance.
