The SRAM PC-XX1 [paid link] chain is a high-performance, lightweight, and durable chain specifically designed for SRAM’s XX1 1x drivetrain system. It features a hollow-pin construction and a Hard Chrome™ finish, enhancing its strength and wear resistance. Proper installation, adjustment, and maintenance are crucial for maximizing its lifespan and ensuring smooth shifting.
This guide covers every step, from fitting the chain correctly to troubleshooting and maintenance.
Tools Required
To install and maintain your PC-XX1 [paid link] chain, you’ll need the following tools:
- Chain breaker tool (compatible with 11-speed chains)
- Master link pliers
- Torque wrench [paid link] (for drivetrain adjustments)
- Chain wear indicator tool
- Lint-free cloth
- Degreaser and chain lubricant (dry or wet, depending on riding conditions)
Installing the PC-XX1 Chain
Step 1: Measure and Size the Chain
Before installing your PC-XX1 chain, you must determine the correct length:
- Shift your derailleur to the smallest cog and smallest chainring.
- Route the chain through the derailleur and cassette without running it through the derailleur pulleys.
- Pull the chain taut and overlap the ends, ensuring a two-link overlap for proper tension.
- Mark the correct length and remove the excess links with a chain breaker.
Step 2: Routing the Chain Correctly
Proper routing ensures smooth shifting and drivetrain efficiency:
- Run the chain through the jockey wheels of the rear derailleur.
- Ensure the printed SRAM logo faces outward for correct orientation.
- Avoid twisting or kinking the chain when threading it through the drivetrain.
Step 3: Connecting the Chain with the PowerLock Link
SRAM’s PowerLock™ master link makes connecting the PC-XX1 chain simple:
- Align both ends of the chain with the PowerLock link.
- Insert the master link halves into the chain ends and push them together.
- Apply firm pedal pressure to snap the link securely into place.
- Verify that the link moves freely before riding.
Adjusting the PC-XX1 Chain for Optimal Performance
Chain Tension and Derailleur Adjustment
Once the chain is installed, check derailleur tension:
- Shift to the largest cog and observe derailleur movement.
- Ensure there’s at least 10-15mm of chain wrap on the largest cog.
- Adjust the B-tension screw if needed to maintain proper gap between the pulley and cassette.
Fine-Tuning Shifting Performance
A properly adjusted chain minimizes skipping and excessive noise:
- Shift through all gears and listen for unusual sounds.
- If shifting is rough, adjust the barrel adjuster in small increments.
- Ensure the chain smoothly engages with the cassette and chainring.
Maintaining the PC-XX1 Chain for Longevity
Cleaning and Lubrication Routine
Regular cleaning prevents premature wear:
- After every ride: Wipe the chain with a lint-free cloth to remove dirt and moisture.
- Every 100 miles: Clean the chain with a degreaser and reapply a suitable lubricant.
- Monthly: Inspect the chain for wear using a chain checker tool. Replace it if it has stretched beyond 0.5%.
Lubrication Tips for Different Conditions
- Dry Conditions: Use a dry lube [paid link] to prevent dust accumulation.
- Wet/Muddy Conditions: Opt for a wet lube [paid link] to maintain durability.
Troubleshooting Common PC-XX1 Chain Issues
Skipping or Slipping Under Load
- Check for chain wear using a wear indicator tool.
- Ensure the cassette and chainring are not excessively worn.
- Inspect derailleur alignment and chain tension.
Noisy Shifting or Chain Rubbing
- Clean and lubricate the chain to reduce friction.
- Fine-tune the derailleur’s barrel adjuster for precise shifting.
- Verify that the chain is correctly routed and the PowerLock link is fully engaged.
Conclusion
Proper installation, adjustment, and maintenance of your SRAM PC-XX1 chain ensure long-lasting, high-performance cycling. By following these steps, you can prevent drivetrain issues and keep your ride smooth.
