Shimano STEPS CN-E6070-9 Chain — Built for the Demands of E-Bike Riding

E-bike drivetrains live a harder life than conventional setups. The motor’s instant, consistent torque loads every link more aggressively than pedaling alone. Standard chains simply weren’t designed for that. Shimano engineered the SHIMANO E6070-9 chain specifically for STEPS e-bike systems, and the difference shows in how it’s built.

Why E-Bike Riders Need a Different Chain

When an e-bike motor assists your pedaling, the chain sees elevated stress with every push of power delivery. Standard chains wear faster under these conditions, which means shorter replacement intervals and accelerated wear on your cassette and chainring. The CN-E6070-9 addresses this directly with reinforced chain plate dimensions that provide additional structural strength where it matters most. It’s a real engineering solution.

SIL-TEC Surface Treatment

Shimano’s SIL-TEC coating reduces metal-on-metal friction across the chain’s contact points. That means smoother power delivery, less heat buildup, and a foundation that plays well with additional chain treatments, including hot wax.

Pre-Waxed and Ready to Ride

This is where Vital Bike Chains comes in. The SHIMANO E6070-9 chain arrives at your door already processed through our 5-step pre-wax treatment: complete degreasing, ultrasonic cleaning, hot wax immersion, break-in, and repackaging. You choose your wax: Silca, Molten, Squirt or Ceramic Speed. A waxed chain runs cleaner and quieter, picks up less grit from the road or trail, and extends drivetrain life further. These benefits compound even more on an e-bike that sees higher chain loads and, typically, more miles.

Is This the Right Chain for Your Setup?

If you’re running a Shimano STEPS 9-speed e-bike drivetrain and want a chain that’s genuinely engineered for the job, the CN-E6070-9 is the correct call. Add pre-waxing and you get a drivetrain that runs cleaner, quieter, and longer between service intervals. For riders putting serious miles on an e-bike, that’s good maintenance math.
