The SRAM Rival DoubleTap shifters [paid link] are an excellent choice for road cyclists looking for precise shifting performance and a streamlined design. Known for their ease of use and solid construction, these shifters can deliver smooth, efficient gear changes when properly installed and maintained.

This guide will walk you through the process of installing, adjusting, and maintaining your Rival DoubleTap shifters [paid link] to ensure they perform optimally for years.

Tools Required

Before starting, gather the following tools for the job:

  • 5mm Allen wrench [paid link]
  • Torque wrench [paid link]
  • Flathead screwdriver
  • 2.5mm Allen wrench [paid link]
  • Cable cutters
  • Lubricant (appropriate for cables)
  • Grease (for parts assembly)
  • Chain tool (if necessary)
  • SRAM Rival cable set
  • Bike stand [paid link] (optional but recommended)

Installing the SRAM Rival DoubleTap Shifters

Step 1: Prepare the Handlebars

Start by preparing your handlebars for the installation of the shifters. If your bike is already equipped with old shifters or grips, remove them carefully. Ensure your handlebars are clean and free of any debris that might interfere with the new shifters.

Step 2: Attach the Shifters to the Handlebars

  1. Slide the shifters onto the handlebars.
  2. Position the shifters so that they are comfortably within reach of your hands when riding.
  3. Ensure that the shifters are aligned straight on the handlebars.
  4. Tighten the clamps using a 5mm Allen wrench [paid link] to secure them in place. Be sure to follow the manufacturer’s torque specifications for optimal installation.

Step 3: Install the Brake Levers (if necessary)

If you’re installing a combined brake and shift lever system (which is typical with the Rival DoubleTap), install the brake levers as part of the process. Align them with the shifters, ensuring that they are at the correct angle for comfortable braking.

Step 4: Install the Cables

  1. Thread the gear cables through the designated openings on the shifter body.
  2. Route the cables towards the rear derailleur and front derailleur (depending on your setup). Follow the manufacturer’s instructions on where to position the cables.
  3. Use cable housing along the cable routing for smooth operation. Make sure to trim excess cable and housing with cable cutters to avoid interfering with the shifter action.

Adjusting the Rival DoubleTap Shifters

Step 1: Set the Initial Cable Tension

  1. Using the barrel adjusters on the shifters, make small adjustments to the cable tension.
  2. Shift to the smallest gear at the rear and front (smallest cog on the cassette and smallest chainring) to make sure the cables have minimal slack.
  3. Check for any signs of friction in the system, such as stiff shifting or misalignment.

Step 2: Fine-tune the Shifting

  1. Shift to the largest gear at the rear and front.
  2. If the shifter is not shifting smoothly, adjust the cable tension again with the barrel adjuster.
  3. Repeat the process in both directions to ensure that the chain moves smoothly from the smallest to the largest cogs without skipping or rubbing.

Step 3: Test the Shifter Range

After adjusting the tension, check the full range of the shifter. The Rival DoubleTap system uses a single lever to shift both up and down:

  • To shift up (to a harder gear), press the thumb lever.
  • To shift down (to an easier gear), press the main lever.

Test both shifts and ensure the transition is smooth without hesitation.

Maintaining the Rival DoubleTap Shifters

Regular Cleaning

To ensure your shifters perform at their best, regularly clean them to remove dirt, grit, and grime that can interfere with the mechanism. Use a damp cloth to wipe down the exterior, being careful not to introduce moisture into the internal parts of the shifter. You can also use a degreaser to clean the cables if they are sticky or show signs of wear.

Lubricating the Cables

Apply a thin layer of lubricant to the cables every 500-1000 miles, especially if you ride in wet conditions. This will reduce friction and extend the life of the cables and housing. Be sure to wipe off any excess lubricant to avoid attracting dirt.

Checking for Wear

Periodically inspect the condition of the shifters:

  • Check the lever action: Ensure that the levers feel firm and responsive. If the levers feel spongy or sluggish, the cables may need to be replaced or re-lubed.
  • Inspect the cables and housing: Look for any frays or signs of wear. Replace any damaged cables immediately to avoid shifting failures.
  • Brake lever condition: If you have combined brake and shifter levers, check for smooth brake lever action as well.

Replacing Cables

Over time, cables may stretch or become frayed. If shifting becomes less precise or the cables show significant wear, replacing them will restore performance. Always use the correct replacement cables and housing for your SRAM Rival DoubleTap shifters [paid link].

Troubleshooting Common Issues with the Rival DoubleTap Shifters

Issue 1: Sluggish or Sticky Shifting

If shifting feels sluggish or sticky, it is usually due to friction from dirty cables or improperly lubricated housing. Clean and lubricate the cables, and ensure there is no dirt buildup inside the shifter mechanism.

Issue 2: Skipping Gears

Skipping gears can occur if the cables are improperly tensioned. Use the barrel adjuster to make small adjustments to the tension until the shifter moves smoothly through the entire gear range. If the problem persists, check for damage in the cable or housing and replace as necessary.

Issue 3: Misaligned Shifters

If the shifters are misaligned on the handlebars, it can affect their performance. Ensure the shifters are securely fastened and aligned with the center of the handlebars for consistent lever action.

Issue 4: Poor Shifting Between Chainrings

If shifting between chainrings is not smooth, it could be a sign of cable stretch, poor derailleur indexing, or incorrect cable tension. Recheck the derailleur and cable settings and adjust accordingly.

Comparison: SRAM Rival DoubleTap Shifters vs. Shimano 105 Shifters

When comparing the SRAM Rival DoubleTap to Shimano 105 shifters, there are a few key differences to note:

  • Shifting Mechanism: The Rival DoubleTap uses a single lever for both up and down shifting, offering a more minimalist design. In contrast, Shimano 105 has separate levers for shifting up and down, which may feel more familiar for those used to traditional gear systems.
  • Weight: The Rival DoubleTap shifters tend to be lighter, which might appeal to riders focused on weight savings.
  • Price: SRAM Rival shifters are generally more affordable, offering a good balance of price and performance.
  • Performance: Both systems provide precise, reliable shifting, but some riders prefer the feel of Shimano 105’s shifting, particularly in terms of tactile feedback.

For those seeking simplicity and weight-saving benefits, the SRAM Rival DoubleTap is a great choice. However, if you prefer the familiarity and traditional design of separate shifters, the Shimano 105 may be more suitable.

Conclusion

Installing, adjusting, and maintaining your SRAM Rival DoubleTap shifters can greatly enhance your cycling experience. With proper care, these shifters will provide smooth, reliable shifting for many miles. Regular maintenance such as cleaning, lubricating, and adjusting cable tension is essential to ensure that the system continues to perform optimally. By following the steps outlined in this guide, you can avoid common issues and keep your shifters in excellent condition.
