The SRAM PC-RED22 [paid link] chain is a high-performance drivetrain component designed for smooth, reliable shifting on road bikes. However, like any other chain, it can sometimes experience issues, such as skipping, which can significantly impact your riding experience. A “skipping” chain refers to the moment when the chain fails to engage properly with the cassette, leading to inconsistent or jerky pedal strokes. This guide will explain why your SRAM PC-RED22 [paid link] chain might feel skippy and offer practical solutions to fix it.

Common Causes of a Skipping Chain

A skipping chain can occur for various reasons, ranging from poor installation to excessive wear. Understanding the root cause will help you quickly address the issue.

1. Chain Wear

As your SRAM PC-RED22 [paid link] chain wears over time, the internal components—such as the rollers and pins—can stretch, causing the chain to skip over the cogs. Chain wear is most noticeable when shifting under load, such as when climbing or sprinting. Over time, the chain’s elongation leads to a poor fit on the cassette teeth, which results in skipping.

2. Incorrect Chain Length

If the chain is too long or too short, it will not properly engage with the cassette. A chain that is too long can cause slack, while a chain that is too short can cause tension. Both situations lead to poor drivetrain performance, which may result in skipping during shifts or under load.

3. Worn Cassette or Chainrings

If your chain is skipping, it could also be a sign that your cassette or chainrings are worn. Over time, teeth on these components become worn down, making it harder for the chain to catch properly. If the cassette or chainrings are excessively worn, replacing them may be necessary to resolve the issue.

4. Misaligned Derailleur

A derailleur that is not aligned properly can cause skipping when the chain fails to move smoothly across the cassette. This misalignment could be due to a bent derailleur hanger, a malfunctioning derailleur, or a poorly adjusted derailleur tension.

5. Improper Chain Lubrication

A chain that is too dry or clogged with dirt and debris may also cause skipping. Proper lubrication is crucial for smooth shifting, and insufficient lubrication can lead to friction, skipping, and even damage to your drivetrain components.

6. Poor Shifting Technique

If you’re shifting under high loads or not releasing enough pressure from the pedals while shifting, you can cause the chain to skip. Forceful shifting without easing off the pedals can result in the chain not catching the teeth correctly, leading to skipping.

Steps to Fix a Skipping SRAM PC-RED22 Chain

Once you’ve identified the cause of the skipping, it’s time to take corrective action. Here are steps you can follow to resolve the issue:

Step 1: Inspect and Measure the Chain for Wear

Check the length of your SRAM PC-RED22 chain using a chain checker tool. If the chain has stretched beyond its recommended limit (typically 0.5% to 0.75% elongation for the PC-RED22), it’s time to replace it. Replacing the chain before it reaches 1% elongation can prevent excessive wear on your cassette and chainrings.

Step 2: Adjust the Chain Length

To adjust the chain length, shift to the largest chainring and the largest cog. With the rear derailleur in this position, remove any slack in the chain by shortening it. The chain should be tight enough to maintain tension without excessive slack but not so tight that it binds when shifting. Ensure that the chain is not too short or too long by checking that it fits smoothly over the gears.

Step 3: Inspect and Replace Worn Components

If the cassette or chainrings show signs of wear, such as worn-down teeth or visible grooves, it’s best to replace these components. A worn cassette will not mesh well with the chain, leading to skipping. The same goes for chainrings. Replace these components before they cause unnecessary wear to the new chain.

Step 4: Realign the Derailleur

Check the derailleur hanger for any bending. A misaligned derailleur can cause skipping by preventing smooth shifting. If the hanger is bent, realign it using a derailleur hanger alignment tool. If the derailleur itself is damaged, it may need replacement or servicing.

Step 5: Clean and Lubricate the Chain

Clean your SRAM PC-RED22 chain thoroughly using a degreaser and a brush to remove dirt and old lubricant. After cleaning, apply a high-quality lubricant designed for road bikes, focusing on the inner links where the rollers engage. Wipe off any excess lube to prevent dirt accumulation. Regular lubrication will keep the chain moving smoothly and help prevent skipping due to friction.

Step 6: Improve Your Shifting Technique

When shifting, ensure you ease off the pedal pressure to allow the derailleur to shift smoothly. Shifting under load is one of the most common causes of chain skipping. By releasing pressure on the pedals when shifting, you allow the chain to move freely and engage with the teeth more effectively.

Preventing Future Skipping Issues

Regular Maintenance

To keep your SRAM PC-RED22 chain running smoothly and prevent skipping, it’s crucial to perform regular maintenance. Clean the chain after every ride, lubricate it regularly, and inspect the chain for wear every few hundred miles. This proactive approach will help you catch issues before they cause significant problems.

Replace Worn Parts Promptly

If you notice that the chain is skipping frequently, it’s essential to check other drivetrain components like the cassette and chainrings. If they are worn, replacing them will prevent excessive wear on your new chain, leading to smoother performance and fewer skipped shifts.

Use Proper Shifting Techniques

Ensure you are using proper shifting techniques by reducing pressure on the pedals when shifting, especially under heavy load or while climbing. This simple habit can greatly reduce the chances of chain skipping and prolong the life of your drivetrain components.

Conclusion

A skipping SRAM PC-RED22 chain is often a sign of wear or incorrect installation, but it can usually be fixed with some simple adjustments. By inspecting your chain, adjusting its length, ensuring your cassette and chainrings are in good condition, realigning the derailleur, and properly lubricating your components, you can restore smooth shifting performance. Regular maintenance and correct shifting techniques will help prevent skipping issues in the future, keeping your drivetrain in top shape for optimal cycling performance.
