The Campagnolo Record 12s [paid link] cassette is one of the finest drivetrain components for high-performance road cycling. Its lightweight design, precision machining, and 12-speed configuration offer smooth gear transitions and optimal efficiency. However, proper installation, regular adjustment, and consistent maintenance are crucial to ensuring the best performance and longevity.
This guide will take you through the step-by-step process of installing, adjusting, and maintaining your Campagnolo Record 12s [paid link] cassette, helping you keep your drivetrain running smoothly.
Tools Required for Installation & Maintenance [paid links]
To install and maintain your Campagnolo Record 12s [paid link] cassette, you will need:
- Campagnolo cassette lockring tool [paid link]
- Allen wrenches
- Torque wrench (for precise tightening)
- Chain whip
- Cassette brush or soft-bristle brush
- Degreaser (bike-specific recommended)
- Clean rags or microfiber cloths
- Lubricant (dry or wet lube [paid link], depending on riding conditions)
- Isopropyl alcohol (for deep cleaning)
Step 1: Installing the Campagnolo Record 12s Cassette
A. Preparing the Freehub Body
Before installing the cassette, ensure that the freehub body is clean and free of debris.
- Remove the rear wheel from the bike and place it on a stable surface.
- If an old cassette is installed, use the chain whip and lockring tool [paid link] to remove it.
- Wipe the freehub body with a clean rag and isopropyl alcohol to remove old grease or dirt.
B. Aligning the Cogs Correctly
The Record 12s cassette is designed with asymmetrical spline patterns, ensuring that each cog fits in only one orientation.
- Begin with the largest cog and slide it onto the freehub body.
- Stack the remaining cogs in descending order, ensuring they align with the splines correctly.
- The last few cogs might be spacer-integrated, so double-check their order before securing the lockring.
C. Securing the Lockring
- Once all the cogs are in place, thread the Campagnolo lockring onto the freehub.
- Use the Campagnolo lockring tool [paid link] to tighten it.
- Torque the lockring to 40Nm using a torque wrench [paid link] for a secure fit.
Step 2: Adjusting the Campagnolo Record 12s Cassette for Perfect Shifting
A. Fine-Tuning the Derailleur for Smooth Shifting
Even a perfectly installed cassette can cause poor shifting if the derailleur is not aligned correctly.
- Check the derailleur hanger alignment: If the hanger is bent, shifting will be inconsistent. Use a derailleur alignment tool to ensure it is straight.
- Set the H and L limit screws: Adjust the high (H) and low (L) limit screws on the derailleur so the chain does not overshift off the cassette.
- Fine-tune the cable tension: Use the barrel adjuster to make small changes to the derailleur cable tension for precise shifts.
B. Testing and Adjusting Under Load
After the initial adjustments:
- Reinstall the rear wheel and shift through the gears while pedaling on a bike stand [paid link].
- If shifting feels sluggish, increase cable tension slightly.
- If the chain skips or hesitates, decrease cable tension.
Step 3: Maintaining Your Campagnolo Record 12s Cassette
A. Regular Cleaning Routine
Dirt and grime buildup can significantly affect shifting quality and cassette lifespan.
- Remove the rear wheel and use a cassette brush to remove surface dirt.
- Apply a bike-specific degreaser and let it sit for a few minutes.
- Use a soft-bristle brush or an old toothbrush to scrub between the cogs.
- Rinse with clean water and dry thoroughly before reinstalling the wheel.
B. Lubrication Best Practices
After cleaning, always reapply lubricant:
- Use a dry lube [paid link] for dry weather conditions or a wet lube [paid link] for wet conditions.
- Apply a small drop of lubricant to each chain link rather than the cassette itself.
- Wipe off excess lubricant to prevent dirt accumulation.
C. Checking for Wear and Replacement Needs
A worn cassette can cause poor shifting and chain skipping. Look for these signs of wear:
- Teeth appearing sharp or “hooked.”
- Chain slipping under load, especially in high-torque situations.
- Excessive noise even after cleaning and lubrication.
If any of these signs appear, replace the cassette before it affects your chain and chainrings.
Troubleshooting Common Issues with the Campagnolo Record 12s Cassette
1. Noisy Shifting or Clicking Sounds
- Ensure the cassette lockring is properly torqued.
- Check for debris or worn chain links.
- Adjust the derailleur’s indexing via the barrel adjuster.
2. Chain Skipping Under Load
- Check for cassette wear—a worn cassette won’t hold the chain properly.
- Ensure the chain is not stretched beyond recommended limits.
- Verify that the rear derailleur clutch (if present) is properly tensioned.
3. Poor Shifting Performance in Certain Gears
- Make sure the cogs are installed in the correct order.
- Adjust the high and low limit screws on the derailleur.
- Check for a bent derailleur hanger.
