The Advent RD-M6195M [paid link] rear derailleur from microSHIFT is a well-designed, reliable component known for its smooth shifting and durability. Regular maintenance and proper adjustments are crucial to ensuring that your derailleur functions optimally and lasts for a long time. This guide will walk you through the key steps to install, adjust, maintain, and troubleshoot the Advent RD-M6195M, along with tips for customization and compatibility considerations.
Installation of the Advent RD-M6195M Rear Derailleur
Proper installation of your Advent RD-M6195M rear derailleur ensures that it performs well from the start. Follow these steps to install the derailleur correctly:
- Prepare the Bike
Ensure that your bike is on a stable surface, preferably in a bike stand. Shift the chain to the smallest cog and the smallest chainring to reduce tension on the derailleur during installation. - Remove the Old Derailleur (if applicable)
If you’re replacing an old derailleur, first remove the chain from the derailleur using a chain tool. Use a 5mm Allen wrench to detach the derailleur from the derailleur hanger. - Install the New Derailleur
Mount the Advent RD-M6195M onto the derailleur hanger and secure it using the mounting bolt. Tighten it firmly but not excessively, as over-tightening can damage the hanger. - Reattach the Chain
If the chain was removed, carefully reinstall it around the derailleur pulleys, ensuring that it runs smoothly through the jockey wheels. - Check Alignment
Make sure the derailleur is aligned properly with the cassette and that it moves freely without obstruction.
Adjusting the Advent RD-M6195M Rear Derailleur
Fine-tuning the derailleur is essential for smooth shifting performance. Here’s how to adjust the RD-M6195M for optimal performance:
1. B-Screw Adjustment
The B-screw controls the distance between the derailleur and the cassette. To adjust it:
- Shift the bike to the largest cog.
- Use a 2mm Allen wrench to adjust the B-screw, ensuring there’s a small gap (around 5mm) between the upper derailleur pulley and the largest cog. If the derailleur is too close or too far, shift performance may degrade.
2. Limit Screw Adjustment
Limit screws control the movement of the derailleur and prevent it from overshooting the cogs. Adjust the high and low limit screws:
- High limit screw: Shift to the smallest cog, and adjust the high limit screw to ensure the derailleur doesn’t shift past the smallest cog.
- Low limit screw: Shift to the largest cog, and adjust the low limit screw to ensure the derailleur doesn’t overshift to the spokes.
3. Indexing
Proper indexing ensures that the derailleur moves smoothly across all gears:
- Shift through each gear and observe the derailleur movement. If shifting is sluggish or skipping, turn the barrel adjuster on the derailleur (counterclockwise for tighter shifting, clockwise for looser shifting) until the shifts are precise.
Maintaining the Advent RD-M6195M Rear Derailleur
Regular maintenance of your Advent RD-M6195M will help keep it performing at its best for a longer time. Here are some maintenance tips:
1. Cleaning the Derailleur
Dirt and debris can accumulate on the derailleur, affecting performance. Regular cleaning is essential:
- Use a soft brush to remove dirt and grease buildup.
- Apply degreaser to the derailleur, especially on the jockey wheels, and wipe it down with a clean cloth.
- After cleaning, apply a small amount of lubricant to the pivot points and jockey wheels to keep them moving smoothly.
2. Lubricating the Derailleur
To ensure smooth movement, lubricate the derailleur regularly:
- Apply a light coat of lubricant to the jockey wheels and the derailleur pivots.
- Be careful not to over-lubricate, as excess grease can attract dirt and grime, causing more wear.
3. Inspecting for Wear
Check the derailleur for any signs of wear or damage, such as bent or cracked parts. If any issues are found, replace the affected components promptly to avoid further damage to the drivetrain.
Troubleshooting Common Issues with the Advent RD-M6195M Rear Derailleur
Occasionally, you might encounter some problems with your rear derailleur. Here are some common issues and how to troubleshoot them:
1. Skipping Gears
If your bike is skipping gears, it may be due to a misaligned derailleur or a problem with the cable tension.
- Check the derailleur alignment with the cassette. If it’s bent, realign or replace the derailleur.
- Adjust the cable tension using the barrel adjuster until the shifts are smooth.
2. Chain Dropping
A chain drop usually occurs when the derailleur doesn’t move the chain to the correct cog, often caused by misadjustment of the limit screws or the B-screw.
- Double-check the high and low limit screws to ensure they are correctly set.
- Ensure the B-screw is adjusted to maintain proper pulley clearance.
3. Slow Shifting
If the shifting feels sluggish, this could be caused by dirt buildup or improper lubrication.
- Clean and lubricate the derailleur and check the condition of the cables.
- Ensure that the derailleur hanger is straight and that there’s no damage to the derailleur.
Customization and Optimization of the Advent RD-M6195M Rear Derailleur
To get the most out of your Advent RD-M6195M, consider these customization options:
1. Adjusting Jockey Wheels
Swapping out the stock jockey wheels for high-quality ceramic or sealed bearing wheels can reduce friction and improve shifting performance.
2. Upgrading the Chain
Pair the Advent RD-M6195M with a high-quality chain that is compatible with your cassette to improve shifting smoothness. A chain that matches your cassette’s speed (e.g., 9-speed) will ensure more accurate shifting.
3. Fine-Tuning Cable Tension
Improper cable tension can negatively impact shifting performance. Make sure to adjust the barrel adjusters to ensure that the derailleur moves precisely across all gears.
Compatibility with Other Drivetrain Components
The Advent RD-M6195M is compatible with 9-speed drivetrains, and it is designed to work seamlessly with microSHIFT’s other components. However, it can also be used with other 9-speed drivetrains, provided they have a similar spacing and compatibility.
1. Compatible Cassettes and Chains
The RD-M6195M is compatible with 9-speed cassettes and chains, so make sure to choose the correct chain and cassette when replacing components. It works best with cassettes in the 11-34T range, but other sizes may also be compatible depending on your riding style.
2. Derailleur Hanger Compatibility
Ensure that your bike’s derailleur hanger is compatible with the Advent RD-M6195M. A bent or misaligned hanger can cause poor shifting performance, even if the derailleur itself is in good condition.
Comparison with Similar Models
The Advent RD-M6195M is a reliable choice for those looking for a durable, affordable rear derailleur. Compared to other entry-level options, such as Shimano Tourney or Altus, the RD-M6195M offers smoother shifting and better build quality at a competitive price. Additionally, its ease of maintenance and compatibility with a range of cassettes make it a versatile option for budget-conscious riders.
The RD-M6195M stands out due to its solid construction, smooth shifting, and user-friendly adjustments. While it may not offer the high-end performance of Shimano’s Deore or XT derailleurs, it is an excellent choice for recreational and casual riders seeking a cost-effective solution without sacrificing reliability.
