The SRAM PC-1170 [paid link] chain is a popular choice for road cyclists, offering excellent performance and durability. To ensure it provides the best shifting performance and longevity, it’s crucial to maintain it properly. This guide will walk you through a detailed maintenance plan for your PC-1170 [paid link] chain, ensuring that it stays in top condition for as long as possible.

Regular Cleaning of the PC-1170 Chain

One of the most important steps in maintaining your SRAM PC-1170 chain is keeping it clean. Dirt, grime, and road debris can build up on the chain, causing friction and wear. To clean the chain effectively, follow these steps:

1. Remove the chain from the bike if needed, or clean it while still mounted.
2. Use a cleaning solution designed for bike chains, ensuring it’s safe for use on the PC-1170 chain material.
3. Apply the cleaner generously to the chain, allowing it to soak for a few minutes.
4. Use a chain cleaning tool or a soft brush to scrub off dirt and grime.
5. Rinse the chain with water to remove excess cleaner and debris.
6. Dry the chain thoroughly with a clean rag or towel to prevent rusting.

Lubrication

Proper lubrication is essential for the smooth operation of your SRAM PC-1170 chain. A well-lubricated chain reduces friction, prevents rust, and extends the lifespan of the components. Here’s how to apply lubrication to the PC-1170 chain:

1. Choose the right lubricant: Select a high-quality bike chain lube. Consider using a wet lubricant for wet conditions and a dry lubricant for dry, dusty environments.
2. Apply the lubricant to the inner side of the chain links. This ensures it gets into the moving parts where friction occurs.
3. After applying the lube, rotate the pedals backward to allow the lubricant to spread evenly across the entire length of the chain.
4. Wipe off any excess lubricant with a clean rag. Too much lubricant can attract dirt, leading to increased wear.

Inspecting for Wear

Over time, the PC-1170 chain will experience wear from the constant pressure and friction of pedaling. To monitor its condition and prevent premature wear on your cassette or chainrings, it’s important to measure the chain’s wear regularly. Here’s how to do it:

1. Use a chain checker tool: This tool will measure the elongation of the chain, indicating how much the chain has stretched over time.
2. Check the chain’s wear regularly, especially if you notice that shifting performance is degrading or that pedaling feels less smooth.
3. Replace the chain once it has stretched beyond 0.5% or 0.75%, depending on the recommendation of your chain manufacturer.

Tension Adjustment

Proper chain tension is essential for optimal performance. A chain that is too tight or too loose can cause poor shifting, chain skipping, or premature wear on drivetrain components. Here’s how to adjust the tension on your SRAM PC-1170 chain:

1. Check the rear derailleur for proper tension when the bike is in the largest gear.
2. If needed, adjust the derailleur hanger or the limit screws to ensure the derailleur is functioning correctly.
3. In some cases, if the chain feels too loose, you might need to check for a worn-out derailleur or cassette.
4. Make sure the chain doesn’t have excessive slack, as this can cause it to skip during pedaling.

Chainring and Cassette Compatibility

To extend the lifespan of your PC-1170 chain, it’s essential to regularly inspect the condition of your chainrings and cassette. If these components are worn, it can lead to poor chain engagement, skipping, and inefficient power transfer. Here’s what to look for:

1. Inspect chainrings: Check for worn or damaged teeth. If the teeth are shark-fin shaped or uneven, it’s time to replace the chainring.
2. Inspect the cassette: Look for worn cogs that no longer provide smooth engagement. If the teeth are worn down significantly, consider replacing the cassette to prevent further damage to the chain.

Storing Your Bike Correctly

If you store your bike for extended periods, especially in areas with high humidity, the chain can rust or corrode. Here are some storage tips to keep your SRAM PC-1170 chain in top shape:

1. Keep the bike indoors in a dry place to avoid exposure to the elements.
2. Clean and lubricate the chain before long-term storage to ensure it remains in good condition.
3. Consider hanging the bike to avoid pressure on the drivetrain, which can affect chain tension and component wear.

Avoiding Premature Wear

To avoid premature wear and tear on your PC-1170 chain, follow these practices:

1. Shift carefully: Avoid shifting under heavy load, such as when climbing steep hills or sprinting, as this can cause excessive wear on the chain.
2. Clean and lube regularly: A clean, well-lubricated chain will last longer and perform better.
3. Replace the chain early: Don’t wait until the chain is too worn, as this can damage your cassette and chainrings. Replace the chain at the recommended elongation threshold to protect your drivetrain.

Conclusion

Maintaining your SRAM PC-1170 chain is crucial for ensuring that your bike performs at its best and lasts as long as possible. Regular cleaning, lubrication, wear checks, and tension adjustments will help you avoid costly repairs and keep your drivetrain running smoothly. By following this maintenance plan, you can extend the life of your chain and ensure a smooth, efficient ride for years to come.
