Introduction to SRAM RED DoubleTap Shifters

The SRAM RED DoubleTap shifters are engineered for high-performance cyclists seeking smooth and accurate shifting, along with intuitive ergonomics. The DoubleTap technology allows the rider to shift up or down with a single lever, offering both simplicity and speed. This makes it easier to stay focused on the ride while keeping the bike’s performance at its peak.

In this article, we’ll cover the installation process, how to fine-tune the adjustments for the smoothest shifting, and how to maintain your shifters to extend their lifespan.

Step-by-Step Installation of SRAM RED DoubleTap Shifters

Installing your SRAM RED DoubleTap shifters requires careful attention to detail. Here’s how to do it correctly:

1. Prepare the Bike and Components

  • Ensure the bike is clean and securely mounted on a bike stand [paid link].
  • Remove any old shifters, cables, and housing if you are replacing existing components.

2. Install the Shifters

  • Attach the left and right shifters to the handlebars using a 2mm Allen wrench [paid link].
  • Tighten the bolts securely, but don’t overtighten, as the handlebar could be damaged.

3. Attach the Brake Levers

  • Adjust the brake levers to your preferred position on the handlebars.
  • Tighten the brake lever bolts with a 3mm Allen wrench.

4. Run the Cables and Housing

  • Begin with the front derailleur cable. Run the cable from the shifter to the front derailleur, ensuring there are no sharp bends or kinks in the cable housing.
  • Repeat the same process for the rear derailleur cable.

5. Install the Brake Cables

  • Insert the brake cables into the shifter housing, securing them properly in place.
  • The brake cable tension should be tight but not overly strained.

6. Test the Shifters and Brakes

  • Shift through all the gears to ensure the cables are installed correctly and that shifting is smooth.
  • Test the brakes to make sure they engage properly.

Adjusting the SRAM RED DoubleTap Shifters

Once your SRAM RED DoubleTap shifters are installed, you will need to adjust them for optimal performance. Here’s how to fine-tune the system:

1. Front Derailleur Adjustment

  • Shift the front derailleur into the smallest chainring and the rear derailleur into the smallest cog.
  • Use the barrel adjuster on the shifter to fine-tune the cable tension. Turning the barrel adjuster counterclockwise will increase tension, while clockwise turns will decrease it.
  • Test shifting to the large chainring. If the derailleur is sluggish, adjust the tension until the shift is crisp.

2. Rear Derailleur Adjustment

  • To adjust the rear derailleur, first ensure the derailleur is in the smallest cog.
  • Use the barrel adjuster at the rear derailleur or shifter to correct shifting issues, such as skipping or slipping.
  • Fine-tune the high and low limit screws on the rear derailleur to prevent it from overshooting the cogs.

3. Brake Lever Reach

  • Adjust the brake lever reach to suit your hand size by moving the brake lever closer or further away from the handlebar.
  • Use the reach adjust screw on the brake lever to make small adjustments.

Maintaining Your SRAM RED DoubleTap Shifters

Proper maintenance of your SRAM RED DoubleTap shifters ensures longevity and smooth operation. Follow these best practices to keep your shifters in excellent condition.

1. Regular Cleaning

  • Clean the shifters using a soft rag and mild degreaser. Avoid harsh chemicals, as they can damage the components.
  • Wipe down the cables and housing, making sure no dirt or grime accumulates in the shifter mechanism.

2. Lubricate the Cables

  • Use a light lubricant on the cables to reduce friction and improve shifting performance.
  • Avoid over-lubricating, as excess grease can attract dirt.

3. Check for Wear and Tear

  • Periodically inspect the shifter and brake cables for fraying or damage.
  • If the cables show signs of wear, replace them immediately to avoid shifting issues or accidents.

4. Adjust Shifter Tension

  • If you notice shifting becoming sluggish or less precise, use the barrel adjusters to re-tension the cables. This helps maintain crisp shifting and ensures the system remains responsive.

Troubleshooting Common Issues with SRAM RED DoubleTap Shifters

Even with the best components, issues can arise. Here are some common problems and how to troubleshoot them:

1. Shifter Won’t Shift Properly

  • This is typically a sign of improper cable tension. Check the barrel adjusters on both the shifter and derailleur.
  • If the problem persists, inspect the cables for fraying or damage.

2. Brake Lever Feels Soft

  • If your brake lever has a soft feel, the brake cables may need more tension. Use the barrel adjusters to tighten the brake cables.
  • Ensure the brake pads are aligned correctly and not excessively worn.

3. Shifter Levers Are Sticking

  • Sticky levers are often caused by dirt or debris trapped inside the shifter mechanism. Clean the shifters thoroughly and lubricate the internal parts lightly.
  • If the issue continues, disassemble the shifter (if you’re comfortable) and check for any obstructions.

Comparison: SRAM RED DoubleTap Shifters vs. Shimano Di2

When deciding between SRAM RED DoubleTap and other systems like Shimano’s Di2, it’s important to consider the differences in shifting performance, weight, and cost.

  • Shifting Mechanism: The SRAM RED DoubleTap uses mechanical shifting with the intuitive DoubleTap lever action. Shimano Di2, on the other hand, offers electronic shifting, which is more precise but requires a battery and wiring.
  • Weight: SRAM RED components are generally lighter, making them a good choice for weight-conscious cyclists.
  • Price: The RED DoubleTap system is often more affordable than Di2, which might be more attractive for riders looking for high performance at a lower cost.

Conclusion

The SRAM RED DoubleTap shifters are a high-quality, performance-oriented option for road cyclists. Installing, adjusting, and maintaining them properly will ensure smooth, reliable shifting for years to come. By following this guide, you’ll maximize the performance and longevity of your shifters, allowing you to focus on what really matters—your ride.
