Replacing the SRAM PC-1170 [paid link] chain is an essential maintenance task for cyclists who want to ensure smooth shifting, increase drivetrain longevity, and enhance overall performance. Over time, chains wear down due to constant use, causing inefficiencies, poor shifting, and even damage to other drivetrain components. This guide will walk you through the entire process of replacing the SRAM PC-1170 [paid link] chain, from preparation to installation, and give you some tips to maximize its performance.

Tools Required

  • SRAM PC-1170 replacement chain
  • Chain tool or powerlink removal tool
  • 5mm Allen wrench [paid link]
  • Chain checker tool
  • Clean rag
  • Degreaser or chain cleaning solution
  • Lubricant (preferably one recommended by SRAM)
  • Torque wrench [paid link] (optional, for precise adjustments)
  • Pedal wrench [paid link] (if removing pedals to access the crankset)

Preparation for Replacing the SRAM PC-1170 Chain

Before diving into the installation, it’s important to prepare your workspace and ensure you have all necessary tools on hand. Make sure your bike is secure and stable. If needed, elevate the rear wheel using a bike stand [paid link] for easy access to the drivetrain.

1. Inspect the Old Chain

Start by checking the current chain for wear using a chain checker tool. The SRAM PC-1170 chain, like most chains, will show signs of wear after prolonged use. If the wear reaches 0.5% or more, it’s time to replace the chain. Worn-out chains cause inefficient shifting and put unnecessary strain on the cassette and chainrings, leading to premature wear of these components.

2. Remove the Old Chain

The easiest method of removal depends on whether your SRAM PC-1170 chain has a PowerLock connector or if it is a traditional chain with rivets. If your chain uses a PowerLock, it can be removed quickly by disconnecting the PowerLock link. If there are no quick links, use a chain tool to remove the chain by pushing out a rivet. Keep the old chain for reference to help with lengthening or shortening the new chain.

How to Install the New SRAM PC-1170 Chain

Once the old chain is removed, it’s time to install the new SRAM PC-1170 chain. Follow these steps to ensure a proper and secure installation.

1. Measure the Chain Length

The first step is to measure the correct chain length. The SRAM PC-1170 chain needs to be the right length for your bike to ensure smooth shifting and optimal performance. To measure:

  • Lay the new chain on a flat surface and compare it to the old chain. If you kept the old chain, align both chains end-to-end, and find the point where they match up.
  • If you’re unsure, you can use the “big chainring, big cog” method. Wrap the chain around the largest chainring and the largest rear cog without threading it through the derailleur. The chain should overlap by two full links. This provides a rough estimate of the required length.

2. Cut the Chain to Size

Once the length is determined, use a chain tool to remove any excess links. Make sure to carefully push the rivets out of the chain while maintaining the integrity of the links. After cutting the chain to the correct length, ensure the ends are clean and free of burrs.

3. Install the New Chain

Position the chain through the front chainrings and rear cassette. If your SRAM PC-1170 chain has a PowerLock link, slide the two ends of the chain together to engage the PowerLock connector. Use a chain tool to press the link into place, ensuring it is secure.

4. Check for Proper Installation

Once the chain is installed, shift through all the gears to check for smooth and precise shifting. Ensure that the chain moves freely without hesitation. If the shifting feels rough or sluggish, check the installation and ensure the chain is properly tensioned.

Adjusting the SRAM PC-1170 Chain for Performance

After installation, the chain may require fine-tuning to achieve optimal performance.

1. Check Chain Tension

If you have a rear derailleur with a clutch, make sure the tension is properly adjusted. If the chain is too tight or too loose, shifting performance will suffer. Adjust the derailleur settings by following your bike’s manual or SRAM’s instructions.

2. Lubricate the Chain

Before taking your bike out for a ride, apply a small amount of lubricant to the inside of the chain while turning the pedals. Wipe off any excess lubricant with a clean rag to prevent dirt from accumulating on the chain. Regular lubrication will help to maintain smooth shifting and protect the chain from corrosion.

3. Inspect the Chainline

Check the chainline to ensure that it is straight. A misaligned chainline can cause wear on your new chain and negatively affect shifting performance. If necessary, adjust your front derailleur or rear derailleur to correct any misalignment.

Maintaining the SRAM PC-1170 Chain

Proper maintenance of your new SRAM PC-1170 chain is essential for prolonging its lifespan and keeping your bike in top condition. Here’s how to ensure the chain continues to perform at its best.

1. Regular Cleaning

Over time, dirt, grime, and grease will accumulate on your chain. Regular cleaning is crucial for ensuring smooth shifting and preventing excessive wear. Use a degreaser and a chain cleaning tool or rag to remove dirt from the chain. Be sure to clean both the inner and outer surfaces of the chain to maintain proper function.

2. Re-lubrication

As you ride, the lubricant on the chain will wear off. Make sure to reapply lube after every ride or whenever the chain feels dry. This will not only keep your chain running smoothly but also protect it from rust and wear.

3. Regular Chain Inspection

Check the condition of your chain regularly, especially if you notice any performance issues. Use a chain checker tool to measure chain wear and replace the chain before it becomes excessively worn. This will help prevent damage to your cassette and chainrings, saving you money in the long term.

Conclusion

Replacing the SRAM PC-1170 chain is a straightforward process, but it requires attention to detail to ensure proper installation and performance. By following the steps outlined in this guide, you can ensure your new chain is installed correctly, adjusted for optimal performance, and maintained for longevity. Regular cleaning, lubrication, and chain inspections will help to extend the lifespan of your SRAM PC-1170 chain, keeping your bike’s drivetrain running smoothly and efficiently for years to come.
