Super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum dur...Super narrow lightweight 11-speed HG-EV symmetrical design chain for smooth shifts and maximum durability. Outer plate design has been developed to reduce the chance of chain suck. Sil-Tec surface treatment technology (PTFE plating) on inner and outer links and rollers that is smooth running and increases durability. Zinc-Alloy plated inner and outer links. Hollow pin for added weight saving. The inner plate has been developed for better contact with gears providing smoother shifting under high load, giving efficient pedalling, increased rigidity and near silent running. The SHIMANO HG901-11 chain receives a complete SIL-TEC treatment on its plates and roller for increased durability and efficiency. Its asymmetric design ensures smooth front and rear shifts while reducing drivetrain noise. Compatible with 11-speed drivetrains, the HG901-11 is also rated for E-BIKE use. Key Features HG-X11 special asymmetric plate design for 11-speed Rear drive Smooth driving without noise Front drive Preserve chain security at cross chainline Front & Rear Shift Smooth and reliable shifting SIL-TEC on Plate/Roller Hollow pin
This guide is for cyclists looking to optimize their 11-speed drivetrain performance with the Shimano Dura-Ace CN-HG901 chain. The key benefit is smooth and efficient shifting, reducing noise and increasing durability. Keep in mind that proper installation and maintenance are crucial for optimal performance.

FAQs
What is SIL-TEC?
SIL-TEC is a surface treatment technology by Shimano that reduces friction and increases durability of the chain.
How often should I lubricate my chain?
Lubricate your chain every 100-200 miles, or more often in wet or dusty conditions.
How do I know when to replace the chain?
Use a chain checker tool. Replace the chain when it reaches the wear limit (usually 0.75% or 1.0% stretch).
Is the CN-HG901 chain compatible with e-bikes?
Yes, the CN-HG901 chain is rated for e-bike use.
What tools do I need to install the chain?
You will need a chain tool to install and remove the chain. A chain wear indicator tool is also recommended.
Can I use any lubricant on the chain?
Use a high-quality chain lubricant specifically designed for bicycle chains.
What material is the chain made of?
The chain is made with zinc-alloy plated inner and outer links.
Troubleshooting
Chain skipping or not shifting smoothly.
Check for chain stretch with a chain checker tool. Inspect derailleurs for proper alignment and adjust cable tension. Ensure the chain is properly lubricated.
Excessive chain noise.
Ensure the chain is clean and lubricated. Check for any bent links or damage. Inspect the derailleurs and adjust as necessary.
Difficulty installing the chain.
Make sure you are using the correct chain tool and following the manufacturer's instructions. Ensure the chain is routed correctly through the derailleurs.

Proper lubrication and maintenance are essential.
Setup, Compatibility & Care
Compatibility: The CN-HG901 is compatible with 11-speed drivetrains. Ensure your cassette, derailleurs, and chainrings are also 11-speed compatible.
Installation: Use a chain tool to properly install the chain, ensuring correct pin alignment. Follow the manufacturer's instructions for the specific chain tool.
Lubrication: Regularly lubricate the chain with a high-quality chain lubricant. Wipe off excess lubricant to prevent dirt buildup.
Cleaning: Clean the chain periodically with a degreaser and a chain cleaning tool. Rinse with water and dry thoroughly before re-lubricating.
Inspection: Regularly inspect the chain for wear and tear. Use a chain checker tool to determine when to replace the chain. Replace the chain when it reaches the wear limit to maintain optimal drivetrain performance and to prevent cassette and chainring wear.
