What You’ll Need
Before diving into the cleaning process, gather the following tools:
- A degreaser or bike-specific chain cleaner
- A cassette cleaning brush or an old toothbrush
- A chain whip (for removing cassette)
- A cassette lockring tool (for removing cassette)
- Warm water
- Microfiber cloth or old rag
- Chain lubricant
Step 1 – Removing the Cassette
To clean the cassette effectively, it’s best to remove it from your bicycle. Follow these steps to remove the cassette:
- Shift your bike into the smallest chainring and the smallest rear cog (gear).
- Secure the chain whip onto the cassette, ensuring it rests on one of the larger cogs.
- Insert the cassette lockring tool into the lockring on the cassette.
- Using a wrench or adjustable spanner, turn the lockring tool counterclockwise to unscrew it.
- Once the lockring is loose, carefully slide off the cassette from the freehub body of the rear wheel.
Step 2 – Cleaning the Cassette
Now that you have the cassette removed, proceed with the cleaning process:
- Fill a bucket or basin with warm water and add a bike-specific degreaser or chain cleaner according to the product instructions.
- Place the cassette in the soapy water, ensuring it is fully submerged.
- Use a cassette cleaning brush or an old toothbrush to scrub off the dirt, grease, and grime from each individual cog.
- Rotate the cassette to clean all sides of the cogs thoroughly.
- Rinse the cassette with clean water to remove any remaining degreaser or cleaner.
- Use a microfiber cloth or old rag to dry the cassette completely.
Step 3 – Lubricating and Reassembling the Cassette
After cleaning, it’s crucial to lubricate the cassette before reassembling it onto the bike:
- Apply a few drops of chain lubricant to each individual cog on the cassette.
- Allow the lubricant to penetrate and settle for a few minutes.
- Wipe off any excess lubricant from the cassette using a clean cloth.
- Slide the cassette back onto the freehub body of the rear wheel in its original position.
- Insert the lockring and hand-tighten it.
- Use the cassette lockring tool to securely tighten the lockring clockwise.
- Ensure the cassette is properly aligned with the derailleur.
