Road Bike Shifter Swap: A Step-By-Step Guide

How to change road bike shifters

Over time, you might find the need to replace your road bike shifters due to wear and tear, upgrading to a better model, or simply personal preference.

Tools You Will Need

Before we dive into the nitty-gritty of replacing your road bike shifters, make sure you have the following tools ready:

  1. Allen wrench set
  2. Cable cutters or bike-specific cable cutters
  3. Screwdrivers (both flathead and Phillips)
  4. Electric tape or zip ties
  5. Grease or lubricant
  6. Replacement shifters (compatible with your bike’s drivetrain)

Step 1: Prepare your bike

To begin, find a clean and open workspace where you can comfortably work on your road bike. Make sure you have enough clearance to maneuver and access all the necessary parts without any hindrances. Keep in mind that road bike shifters are integrated with brake levers, so you will be dealing with both shifters and brake systems.

Next, shift your bike onto the smallest chainring and smallest rear cog. This will relieve tension on the shift cables, making it easier to detach them from the old shifters later on.

Step 2: Remove the handlebar tape

Since you’ll be replacing your road bike shifters, you need to remove the handlebar tape for access. Start from the edge of the tape, either at the handlebar ends or at the shifters. Carefully peel it off, taking care not to tear it as you may want to reuse it later. Once the tape is removed, set it aside in a safe and clean place.

Step 3: Remove the old shifters

Now that you have access to the shifters, it’s time to remove the old ones. The process may vary slightly depending on the specific model and brand of your shifters, but the general steps remain the same.

  1. Locate the bolts on the side or underneath the brake hood. These bolts secure the shifters to the handlebars. Use the appropriate size Allen wrench or screwdriver to loosen and remove them.
  2. Once the bolts are removed, carefully slide the old shifters out from under the handlebar tape. Pay attention to any wires or cables attached to the shifters.
  3. If your road bike shifters have integrated brake and shift cables, you’ll have to detach the cables from the derailleurs. Use cable cutters to cut the metal end caps off the cables and release them from the derailleurs. Make sure to remember or mark which cable goes to which derailleur.

Step 4: Install the new shifters

Now that you have successfully removed the old shifters, let’s move on to installing the new ones. Before proceeding, refer to the shifter’s product manual to ensure you are following the manufacturer’s instructions properly. Here’s a general outline of the installation process:

  1. Start by sliding the new shifters into the handlebars from underneath the bar tape. Ensure they are aligned correctly and oriented according to your preferred position for easy access.
  2. Once the shifters are in place, loosely tighten the bolts to hold them in position temporarily. This will allow adjustments later if needed.
  3. If your new shifters have integrated brake and shift cables, thread the cables through the appropriate channels or ports on the shifters. Follow the cable routing marked on the shifters or consult the manual for guidance.
  4. Reattach the cables to the derailleurs, making sure the correct cable goes to the correct derailleur. Secure the cables using the appropriate tension, ensuring they are neither too loose nor too tight.
  5. Tighten the bolts securing the shifters to the handlebars firmly. Double-check the positioning and ensure there are no loose parts or misalignments.

Step 5: Adjust the shifting system

With the new shifters installed, it’s important to fine-tune your shifting system to ensure smooth and accurate gear changes. Follow these steps to make the necessary adjustments:

  1. Check the cable tensions: With your road bike on a bike stand or flipped upside down, shift through all gears to evaluate the shifting performance. If you notice any sluggishness or hesitations, you may need to adjust the cable tensions.
  2. Fine-tune the indexing: Using the barrel adjusters located on the derailleur or shifters, adjust the indexing to eliminate any chain rub or misalignment during gear changes. Make small adjustments clockwise or counterclockwise until the shifting is smooth and precise.
  3. Test and retest: After making adjustments, take your road bike for a short test ride to verify the shifting system’s functionality. Pay attention to any skipping or excessive noise during gear changes. Repeat the adjustment process if necessary.
  4. Complete the setup: Once you are satisfied with the shifting performance, cut off any excess cable length if needed, leaving enough room for future adjustments. Secure the cable ends with cable end caps using either electric tape or zip ties.
  5. Reinstall the handlebar tape: If you removed the handlebar tape earlier, now is the time to reinstall it. Start from the edge and carefully wrap it back onto the handlebars. Make sure it is snug and properly aligned.

Step 6: Final checks and maintenance

Before hitting the road, perform a final set of checks to ensure everything is in order:

  • Test the brakes: Confirm that the brake lever action is smooth and the braking power is consistent. Adjust the brake calipers if necessary.
  • Verify the shifters: Shift through all gears again to ensure the indexing and cable tensions are still correct post-adjustment.
  • Lubricate moving parts: Apply a small amount of lubricant or grease to the moving parts of the shifters, such as the pivot points. This will enhance their performance and prevent unnecessary wear.
  • Clean up: Take a moment to clean your road bike, removing any grease or dirt that accumulated during the shifter replacement process.

Congratulations! You have successfully changed the shifters on your road bike.
