4. Setup and Installation

Proper installation is crucial for the performance and safety of your SRAM Rival D1 system. If you are not confident in performing these steps, seek assistance from a professional bicycle mechanic.

4.1. Mounting the Shifter/Brake Lever

  1. Securely mount the shifter/brake lever onto your drop handlebars. Ensure the lever is positioned ergonomically for comfortable reach and control.
  2. Tighten the clamp bolt to the manufacturer's specified torque.

4.2. Hydraulic Hose Routing and Connection

  • Route the 1800mm brake hose from the lever to the caliper. The system utilizes Stealthamajig technology for clean and efficient hose routing.
  • Connect the brake hose to the caliper and lever, ensuring a secure, leak-free connection.
  • Bleed the hydraulic brake system according to SRAM's official hydraulic brake bleeding instructions to remove any air and ensure proper brake function.

4.3. Caliper Installation

  • Attach the 2-piston disc brake caliper to your bicycle frame or fork using the included mounting hardware and the appropriate 140/160mm adapter.
  • Ensure the caliper is correctly aligned over the brake rotor (rotor not included) to prevent rubbing and ensure optimal braking performance.
  • Tighten the caliper mounting bolts to the specified torque.

4.4. Pairing with AXS Components

Follow the instructions provided with your other SRAM eTap AXS components to pair the left shifter with your derailleur(s) and other AXS devices.

5. Operating Instructions

5.1. Shifting

The Rival D1 eTap AXS shifter features a single paddle for intuitive electronic shifting. Pressing the paddle will execute a shift command. The specific action (e.g., upshift, downshift) can be customized via the AXS app.

5.2. Braking

Squeeze the brake lever to engage the hydraulic disc brake. The amount of force applied to the lever directly corresponds to the braking power. Apply brakes smoothly and progressively.

5.3. Reach Adjust

The brake lever features a reach adjust function, allowing you to customize the distance of the lever from the handlebar. This adjustment is typically made using a small hex key, accessible from the lever body. Adjust to a comfortable position that allows for full braking power and control.

5.4. AXS App Customization

Download the SRAM AXS app on your iOS or Android smartphone. The app allows you to:

  • Assign specific functions to the left and right shift paddles.
  • Monitor battery levels of your AXS components.
  • Perform firmware updates to add new features and improve performance.
  • Diagnose system issues.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your SRAM Rival D1 system.

6.1. Cleaning

  • Clean the shifter and brake lever regularly with a mild soap and water solution. Avoid high-pressure washing directly on electronic components or seals.
  • Keep the brake caliper and pads free from dirt, oil, and grease.

6.2. Brake Pad Inspection and Replacement

  • Periodically check the brake pads for wear. Replace pads when the friction material is worn down to the wear indicator or if they are contaminated.
  • The 2-piston caliper design offers increased pad clearance, but proper alignment is still essential.

6.3. Hydraulic System Checks

  • Inspect brake hoses for any signs of damage or leaks.
  • If braking performance degrades or the lever feels spongy, the system may need to be bled or the fluid replaced. Refer to SRAM's service instructions.

7. Troubleshooting

This section addresses common issues you might encounter with your SRAM Rival D1 system.

7.1. Shifting Issues

  • No Shift Response: Check battery levels of the shifter and derailleur. Ensure all AXS components are properly paired.
  • Inconsistent Shifting: Verify derailleur alignment and limit screw settings. Check for any obstructions in the drivetrain.

7.2. Braking Issues

  • Spongy Brake Lever: This usually indicates air in the hydraulic system. The system needs to be bled.
  • Reduced Braking Power: Check brake pads for wear or contamination. Ensure the rotor is clean and free of oil. Verify caliper alignment.
  • Brake Rubbing: Re-align the brake caliper. Check for bent rotors or worn wheel bearings.
