Introduction to SRAM Force DoubleTap Shifters

The SRAM Force DoubleTap shifters offer a unique shifting system, utilizing a single lever for both upshifts and downshifts, making them highly efficient and user-friendly. Their primary appeal lies in the ergonomic design, precise shifting, and reduced weight compared to other models in the SRAM lineup.

In this guide, we will walk you through the steps for installing, adjusting, and maintaining the Force DoubleTap shifters. By the end, you’ll have your shifters running at peak performance for an enhanced cycling experience.

Installation of SRAM Force DoubleTap Shifters

Installing SRAM Force DoubleTap shifters is a relatively straightforward task, but it requires attention to detail to ensure everything functions correctly. Follow these steps for a smooth installation:

Step 1: Remove Old Shifters (if replacing)

  • Begin by removing your old shifters using a 5mm Allen wrench [paid link] to loosen the bolts on the handlebars.
  • Carefully disconnect the cables from the existing shifters, making sure to inspect them for wear or fraying. If they’re worn, replace them with new cables.
  • Remove the shifters and handlebar tape if necessary.

Step 2: Attach the New Shifters to the Handlebars

  • Slide the SRAM Force DoubleTap shifters onto the handlebars. Position them at a comfortable angle for your riding style, typically about 3–5 cm from the end of the bars.
  • Tighten the clamp bolts using a 5mm Allen wrench. Be sure not to overtighten, as this can damage the handlebars. A torque of around 5-6 Nm should be sufficient.

Step 3: Install the Cables

  • Install the new cables through the shifter’s cable entry point. Be sure to use high-quality cable housing and ensure there are no sharp bends that could cause friction.
  • Lubricate the cables lightly with bike-specific cable lube or grease for smoother shifting.

Step 4: Attach the Cables to the Derailleurs

  • On the rear derailleur, pass the cable through the anchor bolt and tighten it with a 3mm Allen wrench. For the front derailleur, repeat the process, ensuring the cable is taut.
  • Set the derailleur limit screws (explained in the next section) before finalizing the cable tension.

Step 5: Test the Shifting

  • With the cables attached, test the shifting performance by moving through all the gears. Adjust the barrel adjusters to fine-tune the cable tension until shifts are smooth.

Adjusting the SRAM Force DoubleTap Shifters

Proper adjustment of your SRAM Force DoubleTap shifters is essential to ensure precise, smooth shifting. The main areas to focus on are cable tension, limit screws, and indexing.

Step 1: Adjusting Cable Tension

Cable tension is crucial for smooth shifting. If your shifts feel sluggish or delayed, the cable might be too loose. Conversely, if the derailleur struggles to shift, the cable might be too tight.

  • To adjust, use the barrel adjuster located on the shifter or rear derailleur.
  • Turn the barrel adjuster clockwise to tighten the cable tension or counterclockwise to loosen it.
  • Test shifting after each adjustment, moving through all the gears to find the optimal tension.

Step 2: Setting Limit Screws

To avoid the derailleur shifting too far and causing chain drops or damaging the bike, you need to set the limit screws.

  • Locate the limit screws on your rear and front derailleurs. They are marked with an “L” (low) and an “H” (high).
  • Shift to the smallest chainring and adjust the “L” screw until the derailleur is aligned with the smallest cog.
  • Shift to the largest chainring and adjust the “H” screw until the derailleur is aligned with the largest cog.
  • This will ensure that the derailleur moves correctly across all gears.

Step 3: Indexing the Shifting

Indexing ensures the chain moves smoothly across all gears. If your chain skips or hesitates between gears, you may need to adjust the indexing.

  • Shift to the middle gears and observe how the derailleur shifts.
  • Use the barrel adjuster to make small adjustments until each gear shift is smooth and accurate. Aim for quiet, precise shifting with no hesitation.

Maintaining SRAM Force DoubleTap Shifters

Regular maintenance will keep your SRAM Force DoubleTap shifters operating smoothly for years. Here’s how to maintain them:

Step 1: Clean and Lubricate Regularly

  • Keep your shifters clean and free from dirt and debris by wiping them down after every ride.
  • Use a mild bike cleaner to clean the shifters and cables. Avoid harsh solvents that may damage components.
  • Lubricate the cables and housing once every few months to reduce friction and wear.

Step 2: Inspect Cables and Housing

  • Regularly check the cables for signs of wear, such as fraying or rust. If necessary, replace them to ensure smooth shifting.
  • Inspect the cable housing for cracks or sharp bends, as these can impede shifting performance.

Step 3: Adjust the Shifter Levers for Comfort

  • Over time, your riding preferences may change. The position of the DoubleTap shifter levers can be adjusted for comfort and reach.
  • Use a 3mm Allen wrench to adjust the position of the levers along the handlebars.

Troubleshooting SRAM Force DoubleTap Shifter Issues

Even with proper installation and adjustment, you may encounter a few common issues. Here’s how to fix them:

Problem 1: Shifting is Delayed or Jerky

  • Solution: This issue is often caused by incorrect cable tension. Follow the cable tension adjustment steps above to fine-tune the shifting.

Problem 2: Shifter Levers are Stiff or Unresponsive

  • Solution: Stiff shifters are often a sign of dirt or gunk buildup inside the shifter mechanism. Clean the shifters and lubricate the cables to restore smooth movement.

Problem 3: Chain Drops or Mis-shifts

  • Solution: Check the limit screws on your front and rear derailleurs. If the derailleur is misaligned, adjust the screws to prevent the chain from shifting too far.

Conclusion

Installing, adjusting, and maintaining your SRAM Force DoubleTap shifters is crucial for optimal performance. With regular care and proper adjustments, these shifters can provide reliable, smooth gear transitions for years to come. Whether you’re a seasoned cyclist or a beginner, following these steps will ensure your shifting system is always in top condition.
