How to Replace Bicycle Pedals

Use a pedal wrench.

There are several reasons why you might need to replace bicycle pedals. Maybe you are upgrading from platform pedals to the clipless variety. You might be switching brands or styles. Often, pedals simply wear out and a new pair is necessary. Removing and installing new pedals can infuriate even seasoned cyclists from time to time. However, whatever you do, do not use a hammer or saw to remove your pedals.

Things You'll Need

• Pedal wrench
• Bicycle grease
• Bicycle work stand (optional)

Instructions

1. Secure your bicycle to a bicycle work stand (if you have access to one) or lean it against a sturdy wall or counter. As the bike experts at Park Tool suggest, shift the chain to the largest chainring to avoid cutting your hand or arm on the chainring teeth.

2. Position the right pedal so that the crank arm is about parallel to the ground. Using a pedal wrench, position yourself for removal. Some pedals are overly tight, so leverage is important. Do not get frustrated and take a hammer or saw to your pedals. They will come off eventually. Be sure to use a pedal wrench, as they are specifically designed to remove pedals and provide proper leverage for maximum and efficient torque.

3. Try to grab the opposite crank arm to keep the cranks from spinning as you apply force to remove the right pedal. Turn the pedal wrench counterclockwise to remove the right pedal. Once loose, continue turning counterclockwise until the pedal comes off.

4. Gain leverage over the left pedal. Turn the pedal wrench clockwise to remove the left pedal. Remove the pedal from the crank arm.

5. Apply a generous amount of bicycle grease to the threads of your new pedals.

6. Look for an "L" on the pedal indicating that it is the left pedal. Begin threading it onto your left crank arm with your finger in a counterclockwise direction. Use the pedal wrench to completely tighten the pedal.

7. Begin installing the right ("R") pedal with your finger, threading it in a clockwise direction. Complete the job using a pedal wrench to tighten completely.

Tips & Warnings

• Some pedals do not have "L" and "R" indicators. In these cases, take notice of the thread direction. As Park Tool points out, threads slope upward to the left on the left pedal. Threads slope upward to the right on right pedals.

• A few pedals, such as many Crank Brothers' pedals, do not require a pedal wrench for removal and installation. For most of these pedals, you will need an 8 mm Allen wrench. Remove and install these pedals using the Allen wrench on the back of the crank arm where the pedal spindle comes through.
