The Shimano CN-6701 [paid link] chain is a high-performance 10-speed chain designed to deliver smooth, reliable drivetrain performance. Its asymmetrical design supports precise shifting and reduced friction. However, to maintain this level [paid link] of performance, consistent and proper lubrication and cleaning are essential. In this guide, we’ll cover a detailed routine to help you preserve the efficiency, lifespan, and quiet operation of your CN-6701 [paid link] chain.
Understanding the CN-6701 Chain’s Technical Design
The CN-6701 [paid link] features an asymmetric plate design, which aligns better with Shimano 10-speed road drivetrains. This design enhances shift performance while reducing friction and noise. It also includes a directional installation, meaning the outer and inner plates are optimized for forward and reverse movement, respectively. These characteristics make proper cleaning and lubrication not only beneficial but necessary for long-term functionality.
Why Proper Chain Maintenance Matters
Routine lubrication and cleaning are vital for reducing friction, preventing premature wear, and ensuring optimal chain engagement with cogs and chainrings. Neglecting this can lead to degraded shifting, increased drivetrain noise, and accelerated component wear. For a model like the CN-6701, which is engineered for precise interaction with Shimano’s 10-speed components, poor maintenance can compromise performance significantly.
Tools Required
- Degreaser (bike-specific)
- Chain cleaning tool or brush
- Lint-free cloths
- Chain lubricant (wet or dry lube [paid link] depending on conditions)
- Disposable gloves (optional)
Cleaning Procedure: Step-by-Step Chain Preparation
Begin the maintenance process by removing surface grime. Apply a quality degreaser directly onto the chain or into a chain cleaning tool. Rotate the pedals backward to circulate the chain through the tool, allowing the solvent to break down grease and contaminants.
After several rotations, remove the cleaning tool and use a stiff-bristled brush to scrub areas near the derailleur pulleys and chainrings. Then, rinse with water and thoroughly dry the chain using a lint-free cloth. Pay attention to the chain’s rollers and side plates—these are the primary contact surfaces during pedaling and shifting.
Lubrication: Selecting the Right Product and Application Method
Choose a lubricant based on your typical riding conditions. For wet, muddy conditions, a wet lube [paid link] will offer better protection and water resistance. For dry, dusty environments, a dry lube [paid link] will attract less grit.
Apply lubricant to the inside of the chain links while slowly backpedaling. This ensures the lubricant reaches the rollers, which are the main wear points. After application, wait a few minutes for it to penetrate the chain, then wipe off any excess with a clean cloth. Excess lube attracts dirt and can turn into a grinding paste if not removed.
Post-Lubrication Checks and Best Practices
After lubrication, inspect your drivetrain’s operation. Shift through all gears to ensure smooth engagement. Listen for any irregular noises or resistance, which may indicate insufficient cleaning or excessive lube. It’s also important to keep your drivetrain in a clean state—frequent light cleaning is more effective than infrequent deep cleans.
Maintain a consistent schedule based on your riding frequency. For daily riders or those in adverse conditions, weekly maintenance may be necessary. For recreational cyclists, bi-weekly or monthly care may suffice.
Chain Wear Inspection and Replacement Timing
Even with the best care, chains wear over time. Use a chain checker tool to measure elongation. The CN-6701 should typically be replaced when wear reaches 0.75%. Regular inspection not only maintains performance but also protects other drivetrain components like the cassette and chainrings.
Storage and Off-Season Maintenance Tips
If storing your bike for an extended period, clean and lubricate the chain thoroughly beforehand. Apply a slightly heavier coat of lube than usual, and wrap the drivetrain with a breathable cloth to minimize dust accumulation. Before riding again, wipe off the excess and check for any corrosion.
Conclusion
A well-maintained Shimano CN-6701 chain delivers quiet, efficient, and durable performance. With proper cleaning, targeted lubrication, and regular inspection, you can significantly extend the lifespan of your drivetrain and enjoy a consistently smooth ride. Following the detailed routine outlined above ensures that your CN-6701 chain remains in optimal condition for thousands of miles.
FAQs
1. How often should I clean and lube my CN-6701 chain? It depends on your riding conditions, but a good rule of thumb is every 100–150 miles in dry conditions, and after every wet ride.
2. Can I use WD-40 on my CN-6701 chain? WD-40 is a water displacer, not a lubricant. Use a bike-specific lube for proper chain care.
3. What’s the best lube for wet weather? A high-quality wet lubricant offers better water resistance and stays on the chain longer in rainy or muddy conditions.
4. How do I know if I’ve over-lubed my chain? If your chain feels sticky or collects a lot of dirt quickly, you’ve likely applied too much. Wipe off excess after application.
5. Do I need to remove the chain for deep cleaning? Not necessarily. With a chain cleaning tool and proper technique, effective cleaning can be done with the chain installed.
