How to Replace Pedals on Your Mountain Bike [Without a Wrench]

Last Updated on August 26, 2025 by Jaxon Mike

As an avid mountain biker, I’ve encountered my fair share of challenges when it comes to maintaining and repairing my trusty steed. One common issue that often crops up is the need to replace the pedals on my bike. Whether it’s due to wear and tear, a faulty design, or simply a personal preference, swapping out those old pedals can make a world of difference in your riding experience.

Preparing for the Pedal Replacement Process

Before we dive into the nitty-gritty of the pedal replacement process, let’s take a moment to ensure you have everything you need. The good news is that you don’t necessarily need a wrench to get the job done. In fact, with a few simple tools and a bit of elbow grease, you can easily replace your mountain bike pedals without the need for specialized equipment.

Gather Your Supplies

• New pedals (make sure they’re compatible with your bike’s crankarms)
• Allen wrench or hex key (typically a 6mm or 8mm size)
• Pedal wrench (optional, but can make the process easier)
• Degreaser (to clean the pedal threads and crankarm threads)
• Bike grease or lubricant (to ensure smooth operation)

Step-by-Step Pedal Replacement Guide

Now that you have your tools and supplies ready, let’s dive into the step-by-step process of replacing your mountain bike pedals.

Step 1: Identify the Pedal Thread Direction

Mountain bike pedals typically have a left-hand thread on the left side and a right-hand thread on the right side. This means that the left pedal will unscrew counterclockwise, while the right pedal will unscrew clockwise. Understanding this directional difference is crucial for the successful removal and installation of your new pedals.

Step 2: Remove the Old Pedals

Using your Allen wrench or hex key, loosen the pedal by turning it in the appropriate direction (counterclockwise for the left, clockwise for the right). If the pedal is stuck, you can use a pedal wrench to provide additional leverage. Be gentle and avoid applying too much force, as you don’t want to damage the crankarm threads.

Step 3: Clean the Crankarm Threads

Once the pedal is removed, use a degreaser to thoroughly clean the crankarm threads. This will ensure a clean surface for the new pedal to be installed, helping it to thread on smoothly and securely.

Step 4: Apply Grease or Lubricant

Before installing the new pedal, apply a thin layer of bike grease or lubricant to the threads. This will not only help the pedal thread on easily but also prevent rust and corrosion in the future.

Step 5: Install the New Pedals

Carefully thread the new pedal onto the crankarm, turning it in the opposite direction of the removal process (clockwise for the left, counterclockwise for the right). Use your Allen wrench or hex key to tighten the pedal securely, ensuring it’s snug but not over-tightened.

Step 6: Spin the Pedals and Check for Smooth Operation

Once both pedals are installed, give them a few spins to ensure they’re moving freely and smoothly. If you encounter any resistance or binding, double-check the threading and make any necessary adjustments.

Conclusion

Replacing the pedals on your mountain bike without a wrench may seem like a daunting task, but with the right tools and a little know-how, it’s a surprisingly straightforward process. By following the steps outlined in this guide, you’ll be able to breathe new life into your bike and enjoy a smoother, more comfortable ride on the trails.

Frequently Asked Questions

Can I use the same pedals on a different bike?

Yes, you can typically use the same pedals on a different bike, as long as the crankarm threading is compatible. However, it’s always a good idea to double-check the specifications to ensure a proper fit.

How often should I replace my mountain bike pedals?

The frequency of pedal replacement can vary depending on factors such as usage, terrain, and the quality of the pedals. As a general rule, it’s a good idea to inspect your pedals regularly and replace them when they show signs of significant wear or damage.

Can I use a standard wrench instead of a pedal wrench?

Yes, you can use a standard wrench to remove and install your mountain bike pedals. However, a pedal wrench is specifically designed for this task and can provide more leverage, making the process easier and less likely to damage the crankarm threads.

What should I do if the pedal threads are damaged?

If the crankarm threads are damaged, it’s best to have a professional bike mechanic assess the issue. Attempting to force a new pedal onto damaged threads can lead to further damage and may require more extensive repairs.

Can I use a different type of pedal on my mountain bike?

Yes, you can often use different types of pedals on your mountain bike, as long as they are compatible with the crankarm threading. However, it’s important to ensure the new pedals are suitable for the type of riding you’ll be doing and provide the necessary grip and support.
