2. Installing the Rival eTap AXS Crankset
Step 1: Preparing the Bottom Bracket
Before installing the crankset, ensure your bottom bracket is compatible and properly installed. SRAM Rival eTap AXS [paid link] cranksets use the DUB [paid link] spindle, which requires a matching DUB [paid link] bottom bracket.
- Clean the bottom bracket shell thoroughly using a degreaser.
 - Apply a small amount of grease or anti-seize to the threads or press-fit surfaces.
 - Install the bottom bracket using the appropriate tool, ensuring it is torqued to the manufacturer’s specifications.
 
Step 2: Installing the Crankset
- Insert the drive-side crank arm and spindle through the bottom bracket.
 - Align the non-drive-side crank arm with the spindle splines.
 - Tighten the crank bolt to 54 Nm using a torque wrench [paid link].
 - Double-check that the crankset spins freely without resistance or lateral movement.
 
3. Adjusting the Rival eTap AXS Crankset
Checking for Proper Chainline
A correct chainline ensures smooth shifting and efficient power transfer. SRAM’s Rival eTap AXS [paid link] crankset is optimized for Wide (47.5mm) or Standard (45mm) chainlines, depending on your setup.
- If shifting feels sluggish, verify that the chainline matches your drivetrain components.
 - Misalignment can lead to premature wear and inefficient shifting.
 
Setting Up the Front Derailleur
To ensure optimal front shifting:
- Set the front derailleur height so that there is a 2-3mm gap between the chainring and the derailleur cage.
 - Adjust the low and high limit screws to prevent overshifting.
 - Perform a test shift to confirm smooth transitions between chainrings.
 
4. Maintaining the Rival eTap AXS Crankset
Regular maintenance will extend the lifespan of your crankset and keep it running smoothly.
Cleaning and Lubrication
- Wipe down the crank arms and chainrings with a clean rag after every ride.
 - Use a mild degreaser to clean the chainring teeth and spindle area.
 - Reapply light grease to the spindle before reinstalling.
 
Inspecting for Wear
Every 2,000-3,000 km, check for the following:
- Chainring wear: Look for sharp or hooked teeth, which indicate wear.
 - Crank arm bolts: Ensure they are torqued correctly.
 - Bottom bracket condition: Spin the crankset to check for resistance or roughness, which may indicate worn bearings.
 
5. Troubleshooting Common Issues
1. Crankset Feels Loose
- Check if the crank bolt is torqued to 54 Nm.
 - Inspect the bottom bracket for play or wear.
 - Ensure the spindle is fully seated in the bottom bracket.
