Upgrading your SRAM SX Eagle Crankset [paid link] can be an excellent way to improve your bike’s performance and enhance your riding experience. The SX Eagle crankset [paid link], designed as part of SRAM’s budget-friendly Eagle drivetrain range, offers solid performance. However, as cycling technology evolves, so too does the desire for higher-performance components, better weight savings, and smoother shifting.
In this guide, we’ll explore whether upgrading your SRAM SX Eagle crankset [paid link] is a viable option, the compatibility considerations you need to be aware of, and the best practices to follow to ensure that any upgrades contribute positively to your ride.
Understanding the SRAM SX Eagle Crankset
The SRAM SX Eagle Crankset is part of the Eagle drivetrain family, which includes other models like the GX and XX1 Eagle cranksets. The SX version is designed to offer a more affordable entry point into the Eagle system while maintaining many of the key features that make the Eagle series so popular among mountain bikers.
It is constructed with a strong, aluminum design, and paired with the 12-speed cassette and derailleur system, offering solid shifting performance and durability at a budget-friendly price. However, as with many budget-oriented components, it does come with some limitations when it comes to weight, material quality, and advanced features.
If you’re considering upgrading your crankset, it’s essential to weigh the pros and cons of staying with the SX Eagle versus switching to a more premium model.
Compatibility Considerations for Upgrading the SRAM SX Eagle Crankset
When upgrading any component on your bike, it’s essential to ensure compatibility with your existing drivetrain and other components. Here are some factors to consider before upgrading your SX Eagle crankset:
1. Bottom Bracket Compatibility
The SRAM SX Eagle crankset uses the DUB [paid link] (Durable Unified Bottom Bracket) system, which provides compatibility across different SRAM drivetrains. If you’re upgrading to a different SRAM crankset (like the GX or XX1 Eagle), you’ll likely be able to keep the same DUB [paid link] bottom bracket.
However, if you plan to switch to a non-SRAM crankset, ensure that the bottom bracket is compatible with your frame and the new crankset. For example, if you opt for Shimano or Race Face cranks, you’ll need to choose a bottom bracket that matches both the frame and the crankset.
2. Chainring Compatibility
The SX Eagle crankset comes with a 32-tooth chainring as standard, but the Eagle system allows you to upgrade or switch chainrings for different gear ratios or specific riding conditions. SRAM’s 12-speed chainring standards are compatible across the Eagle range, so you can easily swap the chainring on your SX Eagle crankset for a larger or smaller one.
If you’re upgrading to a higher-end model (e.g., GX or XX1), it’s important to remember that they also use the same Direct Mount chainring system. Therefore, upgrading the chainring alone may be the only change you need to make for better performance without swapping the entire crankset.
3. Crankset Arm Length
One of the key aspects of upgrading your SX Eagle crankset is selecting the right crank arm length. The SX Eagle crankset typically comes with crank arm lengths between 170mm to 175mm. If you are upgrading to a higher-tier Eagle crankset like GX or XX1, they offer similar arm lengths, so you don’t need to worry about compatibility there.
However, if you want to adjust the crank arm length for better pedaling efficiency, make sure that your new crankset offers the correct length options. Switching crank arm lengths is a common upgrade, and it’s an easy process when replacing with compatible cranksets.
4. Weight Considerations
If weight savings is your primary motivation for upgrading, then consider that the SX Eagle crankset is built with a slightly heavier, aluminum construction compared to the more premium models. Upgrading to something like the GX or XX1 will result in weight savings due to lighter materials such as carbon fiber. These weight savings may not be drastic, but they can make a difference if you’re looking for a more competitive edge.
When Should You Upgrade Your SRAM SX Eagle Crankset?
Upgrading the SRAM SX Eagle crankset can make a significant difference in your bike’s performance, but it’s important to consider whether you really need an upgrade. Here are some scenarios where upgrading might be worth the investment:
1. Performance Improvement
If you find that your current crankset is not performing at the level [paid link] you desire—whether it’s due to poor power transfer, flex, or wear—upgrading to a higher-end Eagle crankset like the GX or XX1 can provide smoother shifting and improved power transfer. These cranksets are made from higher-quality materials, offering less flex and more efficient pedaling.
2. Weight Reduction
For those aiming for weight savings, upgrading to a lighter crankset can shave off some grams from your bike’s overall weight. While the difference between the SX Eagle and premium models might not be massive, every gram saved can help, especially if you’re trying to optimize your bike for racing or aggressive trail riding.
3. Durability and Longevity
If you’re looking for a crankset with greater durability and longer lifespan, a higher-end model will typically offer better resistance to wear. The GX and XX1 cranksets are engineered to handle more extreme conditions and are made with superior materials that resist damage and bending, which is particularly beneficial if you’re riding rough terrain or in challenging conditions.
4. Customization for Specific Riding Styles
If you have specific needs in terms of chainring sizes, crank arm lengths, or pedal system compatibility, upgrading your crankset allows you to customize your bike to suit your riding style better. The premium Eagle models offer more flexibility in terms of customization, such as more choices for chainring sizes and crank arm lengths.
Best Practices When Upgrading Your SRAM SX Eagle Crankset
If you decide that upgrading your SRAM SX Eagle Crankset is the right choice for your bike, here are some best practices to ensure a successful installation and optimal performance:
1. Ensure Proper Bottom Bracket Installation
Before swapping cranksets, double-check that your bottom bracket is properly installed and in good condition. A faulty or worn-out bottom bracket can cause issues like wobble and misalignment, which will negatively affect the performance of your new crankset.
2. Proper Torque Settings
When installing or upgrading your crankset, ensure that you follow the manufacturer’s torque specifications for the crank arm bolts and chainring bolts. Over-tightening or under-tightening these bolts can result in damage to the crankset or improper function.
3. Use High-Quality Chainring Bolts and Hardware
Upgrading the chainring is one of the simplest and most effective ways to improve your performance without replacing the entire crankset. Ensure that you use high-quality chainring bolts and follow proper torque settings to secure the chainring tightly. This will prevent it from slipping or loosening over time.
4. Regular Maintenance
Even after upgrading, it’s important to maintain your new crankset properly. Clean and lubricate the crankset regularly, especially the chainring and bottom bracket, to ensure smooth performance. Check for any wear or damage after riding in harsh conditions, and replace components as necessary to keep everything running smoothly.
Conclusion
Upgrading your SRAM SX Eagle crankset can enhance your bike’s performance and extend the lifespan of your drivetrain. By ensuring compatibility with your frame, bottom bracket, and chainring, you can enjoy the benefits of a higher-end crankset without issues. Whether you’re looking to shave weight, improve durability, or enhance power transfer, upgrading to a GX or XX1 Eagle crankset [paid link] offers numerous advantages.
However, it’s crucial to approach the upgrade process with careful consideration of your riding needs, budget, and overall bike compatibility. By following best practices and paying attention to crucial details like torque settings and bottom bracket installation, you can ensure that your upgrade delivers optimal performance for years to come.
