Product Information
Full details
The SunRace E-Bike Chain is an essential drivetrain component designed specifically for 10-speed electric bicycles, making it an ideal choice for riders looking to replace worn components with a high-durability solution. Its primary benefit is the combination of chromized pins and Teflon-coated inner plates, which work together to handle the intense torque loads of mid-drive and hub-drive e-bike motors while maintaining smooth shifting. Potential users should note that the 138-link length may require significant shortening to fit specific frame geometries, and it requires a compatible 10-speed drivetrain setup.

FAQs
Is this chain compatible with 11-speed e-bikes?
No, this chain is specifically engineered for 10-speed drivetrain systems.
Do I need a special tool to install this?
Yes, you will need a standard bicycle chain breaker tool to remove excess links and join the chain.
How often should I replace my e-bike chain?
Due to high torque, check for wear every 500-800 miles; replace it immediately if the chain checker indicates 0.75% wear.
Does the chain come with a master link?
Please check the specific packaging provided by the retailer, as some versions include a missing link/quick-link while others may require a pin replacement.
Why is the chain Teflon coated?
The Teflon coating is designed to reduce friction between the chain and the cassette, which helps prolong the life of both components and improves shifting performance.
Troubleshooting
Skipping gears after installation
Ensure the chain is properly sized for your drivetrain and verify the derailleur tension; you may need to adjust the cable tension via the barrel adjuster.
Chain making a grinding noise
Ensure the chain is fully lubricated with a high-quality e-bike specific lubricant; dry chains under high torque will cause excess noise.
Difficulty shifting into larger cogs
Check that the chain length is not too long, which can leave the rear derailleur cage with insufficient tension to wrap the chain correctly.
Pros and Cons
Pros
- Increased durability specifically for high-torque electric motors
- Teflon coating provides smoother and quieter gear changes
- Highly resistant to pin-stretch and wear
- Extended link count ensures compatibility with larger e-bike frames
Cons
- Requires professional chain-breaking tools for installation
- Heavier than standard non-e-bike chains
- 138 links may be excessive for smaller frames, requiring removal of extra links
Setup, Compatibility & Care
Installation should be performed using a high-quality chain tool to ensure the pin is seated correctly. Since the chain arrives with 138 links, use a chain wear indicator to measure your current chain's length before cutting the new one to match. Compatibility is limited to 10-speed drivetrains; it will not function correctly on 9-speed or 11-speed systems. To maintain the chain's longevity, use a dedicated e-bike chain lubricant rather than thin, light oils. Clean the chain every 150-200 miles to remove road grime, which acts as an abrasive, and check for wear using a chain checker tool to replace it before it damages your cassette.
