  • 8mm Allen wrench
  • Chain tool
  • Flathead screwdriver
  • Cable cutters (if installing non-electronic components)
  • SRAM AXS app (for syncing and fine-tuning)
  • Grease
  • Bike stand
  • Digital calipers (for precise measurements)

Installation of Rival XPLR eTap AXS

Installing the SRAM Rival XPLR eTap AXS on your gravel bike involves several steps, from mounting the components to configuring the eTap shifting system. Below is an overview of the installation process:

1. Installing the Crankset and Bottom Bracket

The Rival XPLR eTap AXS utilizes a DUB bottom bracket and an AXS-specific crankset. Start by applying a small amount of grease to the bottom bracket threads to prevent creaking and corrosion. Install the bottom bracket into the frame using the appropriate tool. Next, attach the crankset to the DUB spindle, securing it with the specified torque setting to avoid any damage.

2. Mounting the Front Derailleur

Position the front derailleur on the seat tube or braze-on mount, depending on your bike frame. Ensure that the derailleur is aligned with the crankset to maintain optimal shifting performance. Tighten the mounting bolts securely.

3. Installing the Rear Derailleur

Attach the rear derailleur to the derailleur hanger, ensuring it is aligned with the frame. The Rival XPLR eTap AXS rear derailleur features a long cage design for compatibility with wide-range cassettes. Use a torque wrench to tighten the derailleur hanger bolt to the recommended specifications.

4. Installing the Shifters

For the Rival XPLR eTap AXS, you’ll need to install the eTap wireless shifters onto the handlebars. Ensure the position is comfortable and accessible. Attach the shifters using the appropriate clamps, making sure they are securely fastened. These shifters do not require any cable routing, as they communicate wirelessly with the derailleurs.

5. Chain Installation

Using a chain tool, install the appropriate length chain that matches your cassette size. The Rival XPLR eTap AXS supports a wide range of cassettes, so ensure the chain is the correct length to accommodate the largest cog.

6. Configuring the eTap System

Finally, use the SRAM AXS app to wirelessly sync the shifters and derailleurs. The app will guide you through the pairing process and allow you to fine-tune the system for optimal shifting performance. Adjust the trim on the front derailleur if necessary to ensure smooth, consistent shifting across all gear combinations.

Maintenance of Rival XPLR eTap AXS

To keep your Rival XPLR eTap AXS groupset in top working condition, regular maintenance is crucial. Below are essential maintenance tasks for this groupset:

1. Cleaning the Drivetrain

Regularly clean the chain, cassette, and chainrings to prevent dirt and grime from interfering with the shifting performance. Use a mild degreaser and a soft brush to remove debris. After cleaning, apply lubricant to the chain to maintain smooth operation.

2. Checking Battery Life

The Rival XPLR eTap AXS system relies on rechargeable batteries in both the shifters and derailleurs. Regularly check the battery status via the SRAM AXS app and charge the batteries as needed. A full charge typically lasts around 20-30 hours of riding.

3. Inspecting the Derailleurs and Shifters

Check the rear and front derailleurs for any signs of wear or damage. Inspect the mounting bolts to ensure they are securely tightened. Clean the derailleur pulleys and ensure they rotate smoothly. Similarly, check the eTap shifters for any malfunctions or connectivity issues.

4. Lubing the Chain

To ensure smooth shifting and reduce wear, it’s essential to lubricate the chain regularly. Apply a bike-specific chain lube and wipe off any excess to prevent dirt buildup.

Troubleshooting Common Set-Up Issues

While the Rival XPLR eTap AXS is a high-performance groupset, occasional issues can arise. Here are some common problems and their solutions:

1. Misaligned Shifting

If you experience poor shifting performance, check the alignment of the derailleurs. Ensure the front derailleur is aligned with the chainrings, and the rear derailleur is properly tensioned. Use the AXS app to fine-tune derailleur positions and adjust trim settings.

2. Battery Connectivity Issues

If the system isn’t responding, check the battery levels in the shifters and derailleurs. If the batteries are full, try resetting the eTap system by disconnecting the batteries and reconnecting them after a few seconds. Ensure the firmware is up-to-date by using the AXS app.

3. Chain Drop on Shifts

Chain drop, especially on larger cogs, may be caused by improper derailleur alignment or chain length. Ensure the derailleur is properly tensioned and the chain length is correct for the cassette size. Also, check for excessive wear on the chain and replace it if necessary.

Customization and Optimization for Better Performance

The Rival XPLR eTap AXS provides several customization options to optimize your bike’s performance on gravel adventures:

1. Fine-Tuning with the AXS App

The SRAM AXS app allows you to fine-tune shifting performance, adjust trim settings for front derailleur movement, and even customize button functions for the eTap shifters. Take full advantage of these settings to tailor the groupset to your riding style.

2. Gear Ratio Optimization

The Rival XPLR eTap AXS is compatible with a wide range of cassettes, with the XPLR-specific cassette offering a 10-44T gear range. If you prefer more climbing power, opt for a 10-36T cassette. Adjusting the chainring size is also a viable option to fine-tune your gear ratios depending on your typical terrain.

3. Upgrading to a Wide-Range Cassette

For riders tackling challenging gravel routes with varied gradients, upgrading to a 10-44T cassette allows for greater gear range and smoother transitions. The wide-range cassette paired with the Rival XPLR system offers ideal gearing for steep climbs and fast descents.

Compatibility with Other Drivetrain Components

The Rival XPLR eTap AXS is designed to be compatible with most modern SRAM AXS components. However, compatibility considerations must be taken into account:

1. Compatibility with Non-AXS Components

While the Rival XPLR eTap AXS groupset is designed to work seamlessly with other AXS components, it may not be fully compatible with non-AXS mechanical groupsets. When mixing components, ensure that the derailleurs and shifters are designed for electronic or wireless operation for optimal performance.

2. Chain and Cassette Compatibility

The Rival XPLR eTap AXS supports a range of SRAM 12-speed cassettes. It is important to choose a compatible cassette that works within the range of the derailleur’s capabilities to ensure smooth shifting. Also, use a compatible chain designed for the 12-speed system for best results.

Comparison with Similar Models

When compared to other gravel-specific groupsets like the SRAM Force eTap AXS or Shimano GRX Di2, the Rival XPLR eTap AXS stands out for its affordability without compromising performance. The Rival XPLR is a great choice for riders seeking the benefits of AXS wireless shifting and a broad gear range but at a lower price point. While the Force eTap AXS offers more refined features and higher-end materials, the Rival XPLR is an excellent option for those who want electronic shifting without breaking the bank.

In terms of gear range, the Rival XPLR eTap AXS offers a unique advantage for gravel riders with its 10-44T cassette, allowing for better climbing and descending versatility compared to Shimano GRX, which typically offers a narrower gear range.

Conclusion

The SRAM Rival XPLR eTap AXS is a high-performance groupset designed to enhance your gravel biking experience by providing a broad gear range, smooth shifting, and wireless operation. By following proper installation, maintenance, and troubleshooting techniques, you can keep your Rival XPLR system in optimal condition for all your gravel adventures.
