The SRAM RED eTap AXS Crankset [paid link] is a state-of-the-art component in the world of road cycling. It provides exceptional performance, shifting precision, and durability for cyclists who demand the best from their equipment. While the RED eTap AXS Crankset [paid link] is already an excellent choice for high-end performance, many riders are interested in upgrading it to further enhance their cycling experience. Whether you’re looking to improve power transfer, reduce weight, or customize the setup to suit your riding style, understanding the compatibility and best practices for upgrading the RED eTap AXS Crankset [paid link] is essential.

Understanding Compatibility with Other Drivetrain Components

Before jumping into an upgrade, it is crucial to understand how the RED eTap AXS [paid link] Crankset integrates with other components of your bike’s drivetrain. Compatibility is key to ensuring smooth, efficient performance. Here are a few key factors to consider:

Chainring Compatibility

The RED eTap AXS [paid link] Crankset is designed with AXS technology, which allows riders to swap chainrings quickly and easily. However, it is essential to use chainrings that are specifically designed for the AXS system to ensure proper fitment and smooth shifting. If you are looking to upgrade the chainrings, make sure to choose a compatible model from SRAM’s AXS-compatible range, such as the SRAM RED, Force, or Rival chainrings [paid link].

Bottom Bracket Compatibility

The RED eTap AXS [paid link] Crankset uses the DUB [paid link] (Durable Unified Bottom Bracket) system, which ensures better power transfer and improved durability. When upgrading or replacing the crankset, it’s important to use a compatible bottom bracket. Make sure the bottom bracket type aligns with your bike frame’s specifications. The DUB [paid link] system works with both press-fit and threaded bottom brackets, but you must ensure that the specific bottom bracket fits your bike frame’s bottom bracket shell.

Drivetrain Compatibility

The RED eTap [paid link] AXS Crankset is part of SRAM’s AXS electronic drivetrain system. While the crankset is fully compatible with other AXS components, such as the rear derailleur and shifters, it’s important to ensure your entire drivetrain is AXS-compatible for the best experience. If you plan to upgrade your crankset but keep non-AXS components, you may experience performance inconsistencies. For optimal performance, it is advisable to pair the crankset with other AXS drivetrain parts.

Upgrading Chainrings for Enhanced Performance

One of the most popular upgrades for the RED eTap [paid link] AXS Crankset is the chainring swap. Depending on your riding style, terrain, and power requirements, upgrading to a larger or smaller chainring can make a significant difference in your cycling experience.

  • Larger Chainrings: For cyclists who race or ride on flat terrain, larger chainrings provide better high-speed performance by enabling smoother, more efficient power transfer. A 53-tooth chainring, for example, is ideal for maximizing speed in competitive environments.
  • Smaller Chainrings: If you often ride hilly terrain or require more torque for climbing, switching to a smaller chainring, such as a 46-tooth or 44-tooth, will provide more control and reduce the strain on your legs.

When upgrading the chainrings, always ensure they are AXS-compatible. The RED eTap [paid link] AXS system allows for seamless shifts, but using chainrings designed for electronic shifting ensures the best compatibility and performance.

Upgrading the Crankset to Lighter or Stiffer Models

While the RED eTap AXS Crankset is already lightweight and stiff, some cyclists prefer to upgrade to even lighter or stiffer models for specific riding conditions. If you are looking to reduce weight, consider using a carbon fiber crankset instead of the aluminum version. Carbon cranksets offer significant weight savings without compromising strength.

For those looking for stiffness to improve power transfer, upgrading to a crankset with enhanced stiffness can improve performance, especially during sprints. This is often a trade-off for weight savings, as stiffer cranks may be slightly heavier. Always test compatibility before purchasing, and ensure that your upgrade does not interfere with other drivetrain components.

Replacing the Crankset: A Guide to Installation

Upgrading the entire crankset on your bike can be an effective way to improve overall performance. However, it’s important to approach installation with care to ensure everything is properly set up. The process involves removing the existing crankset, installing the new model, and making adjustments to the bottom bracket, chainrings, and other components.

Step 1: Remove the Old Crankset

  1. Remove the crank arm bolts using a torque wrench [paid link] to avoid damaging threads.
  2. Slide the crank arms off the spindle.
  3. If replacing the bottom bracket, remove it carefully to avoid damaging your bike frame.

Step 2: Install the New Crankset

  1. Align the new crankset with the DUB [paid link] bottom bracket and ensure proper positioning on the spindle.
  2. Torque the crank arms according to the manufacturer’s recommended specifications to prevent damage.
  3. Install the new chainrings, making sure they are securely attached to the crankset.
  4. Reinstall the pedals, ensuring they are tightly fastened.

Step 3: Adjust Shifting and Performance

After installing the upgraded crankset, it is essential to adjust your drivetrain components. Test the shifting and ensure the front derailleur is aligned with the chainrings. Make necessary fine-tuning adjustments to the derailleur limit screws to prevent chain drops or mis-shifting. Also, check for any unusual noises that might suggest misalignment.

Best Practices for Maintaining an Upgraded RED eTap AXS Crankset

To ensure longevity and optimal performance after upgrading your RED eTap AXS Crankset, follow these maintenance tips:

  1. Regular Cleaning: Clean your crankset and drivetrain regularly to prevent dirt and grime buildup. Use a gentle degreaser and a soft brush to scrub the crankset, chainrings, and bottom bracket area.
  2. Lubrication: Apply a light coat of grease to the spindle before installing the crankset. This will prevent creaking and facilitate easy removal during future upgrades or servicing.
  3. Check Chainring Wear: Over time, chainrings will wear out due to chain friction. Regularly inspect them for signs of wear, including teeth sharpening, hooking, or excessive wear. Replace them as necessary to avoid poor shifting performance.

Conclusion

Upgrading your SRAM RED eTap AXS Crankset can enhance your riding experience, whether you’re looking to improve power transfer, reduce weight, or customize your setup for specific riding conditions. By understanding compatibility with other drivetrain components, carefully selecting your upgrades, and following best practices for installation and maintenance, you can maximize the performance and longevity of your crankset. Always ensure that any upgrades or replacements align with your bike’s specifications and the rest of your drivetrain for the best results.
