Installation of the Race Face Next SL 29 Crankset

Installing the Next SL 29 crankset correctly is essential to ensure proper performance and longevity. Follow these steps for a smooth installation:

Tools Required

  • 8mm Allen wrench [paid link]
  • Crankset puller tool
  • Torque wrench [paid link]
  • Race Face Cinch System tool
  • Chainring bolts and washers (if replacing the chainring)

Installation Steps:

  1. Remove the Old Crankset:
    • Use an 8mm Allen wrench [paid link] to remove the bolts holding the crankset in place.
    • If applicable, use a crankset puller tool to remove the crank arms from the bottom bracket.
  2. Prepare the Bottom Bracket:
    • Ensure the bottom bracket is clean and properly lubricated. Check for any wear or damage before installing the new crankset.
  3. Install the Race Face Cinch System:
    • The Next SL 29 crankset uses the Cinch system for quick and easy installation of chainrings. Align the Cinch system and insert it into the bottom bracket.
    • Tighten the Cinch system using the appropriate tool, following the manufacturer’s torque specifications.
  4. Attach the Crank Arms:
    • Slide the crank arms onto the Cinch system. Ensure they are correctly aligned, and torque the bolts to the manufacturer’s recommended specification.
  5. Install the Chainring:
    • If you are adding or replacing a chainring, position it onto the Cinch system. Secure it with the chainring bolts and washers.
    • Torque the bolts to ensure proper attachment.
  6. Check for Free Movement:
    • Ensure the crankset is free from any resistance or noise when manually spinning the cranks. Tighten any bolts that feel loose.

Adjustment and Fine-Tuning

Once the Race Face Next SL 29 crankset is installed, fine-tuning adjustments are necessary to optimize performance.

Bottom Bracket Compatibility:

  • Ensure the bottom bracket type is compatible with the Cinch system. The crankset works best with Race Face’s Cinch system, but it is compatible with various bottom bracket standards including BSA, PF30, and more.

Chainring Alignment:

  • Check that the chainring is properly aligned with the chain. Misalignment can cause increased wear on the drivetrain or poor shifting performance.
  • Adjust the position of the chainring if necessary to ensure optimal chainline alignment.

Crank Arm Torque:

  • Recheck the torque on the crank arm bolts using a torque wrench [paid link]. Proper torque ensures there is no unwanted play in the crankset and prevents it from loosening during rides.

Maintenance of the Next SL 29 Crankset

Proper maintenance will ensure your Race Face Next SL 29 crankset remains in top condition, even after extensive use.

Cleaning:

  • Regularly clean the crankset using a soft cloth and degreaser. This helps remove dirt, debris, and grime that can cause wear over time.
  • Avoid using harsh chemicals that can degrade the carbon fiber material.

Lubrication:

  • Lubricate the pedal threads before attaching the pedals to prevent corrosion and ensure smooth installation.
  • Ensure that the Cinch system interface is kept free from contaminants. Apply a thin layer of grease on the interface during maintenance to keep everything running smoothly.

Regular Inspections:

  • Inspect the crank arms and Cinch system for any cracks or signs of wear, especially after long rides or rough terrain.
  • Check the chainring bolts periodically to ensure they are securely fastened.

Troubleshooting Common Issues

1. Loose Crankset:

  • If the crankset feels loose or wobbly, recheck the torque on the crank arm bolts and Cinch system interface.
  • Inspect the bottom bracket for any damage that may require replacement.

2. Chainring Alignment Problems:

  • If the chain skips or the shifting feels erratic, check the alignment of the chainring.
  • Misalignment may be due to improperly torqued chainring bolts or a poorly adjusted bottom bracket.

3. Noisy Crankset:

  • A noisy crankset can result from dried-out bearings or debris in the Cinch system. Clean and lubricate the system regularly to prevent these issues.

4. Difficulty with Pedal Installation:

  • If the pedals don’t fit or are difficult to attach, make sure you’re using the correct pedal type and properly lubricating the threads.

Customization and Optimization for Better Performance

The Race Face Next SL 29 crankset is designed to offer excellent power transfer and stiffness, but customization options can help you further optimize it for your specific riding needs.

1. Chainring Selection:

  • The Cinch system allows you to easily swap out the chainring to suit your riding style. Consider using a narrow-wide chainring for improved chain retention during rough terrain or races.
  • Opt for a smaller or larger chainring depending on whether you prefer higher cadence or more torque during climbs.

2. Pedal Options:

  • The crankset is compatible with a wide variety of pedals, including both clipless and flat options. Choosing the right pedals for your riding style can enhance comfort and efficiency.

3. Crank Arm Length:

  • The Next SL 29 crankset comes with different crank arm lengths, allowing you to choose the length that best fits your pedaling style and body geometry. Shorter arms provide faster cadence, while longer arms offer more torque for climbing.

Comparison with Similar Models

While the Race Face Next SL 29 is a standout option for competitive cycling, it’s important to compare it to other high-performance cranksets to make an informed choice.

Race Face Atlas Crankset:

  • The Atlas crankset is designed for more aggressive riding and downhill use. While it offers superior strength, the Next SL 29 is lighter, making it more suitable for cross-country and competitive racing.
  • The Atlas crankset uses a similar Cinch system, but it is generally heavier and not as optimized for weight-conscious racers.

Shimano XTR M9100:

  • Shimano’s XTR M9100 [paid link] is another popular choice among competitive cyclists. While it provides excellent performance and shifting, the Next SL 29 offers better weight savings without compromising stiffness.
  • The XTR crankset is heavier and typically more expensive, but it is known for its durability in tough conditions.

SRAM XX1 Eagle:

  • SRAM’s XX1 Eagle crankset is renowned for its performance in cross-country and endurance racing. It features a similar carbon fiber design but lacks the versatility and ease of use of the Cinch system used in the Race Face crankset.

Compatibility with Other Drivetrain Components

The Race Face Next SL 29 crankset is highly versatile [paid link] when it comes to compatibility with other drivetrain components.

1. Rear Derailleurs and Cassettes:

  • The crankset is compatible with most modern 11-speed and 12-speed drivetrains. It works seamlessly with both SRAM Eagle and Shimano drivetrains, offering smooth power transfer and efficient shifting.

2. Chain Compatibility:

  • It is recommended to use a narrow-wide chainring for optimal performance, particularly with 12-speed chains. This ensures better chain retention during rides.

3. Bottom Bracket Compatibility:
