Ready to get those pedals off? Let’s walk through exactly how this works step by step.

Getting Those Mountain Bike Pedals Off

Taking off your mountain bike pedals is a fundamental bike maintenance task. You’ll need a few basic tools. Most bikes use either a pedal wrench or an Allen key for removal. This guide will walk you through the process step-by-step, ensuring you don’t damage your bike.

Understanding Pedal Removal Basics

Before you start turning, it’s essential to know the direction to turn. Most pedals, like standard screws, tighten clockwise and loosen counter-clockwise. However, there’s a crucial difference for pedals. You need to remember that the drive-side pedal (the one on the same side as your chainrings) loosens in the opposite direction of a normal screw. It loosens counter-clockwise.

On the other hand, the non-drive-side pedal (the one opposite the chainrings) usually loosens in the conventional counter-clockwise direction. This can be confusing, so always double-check. A little memorization goes a long way here. Think of it as learning a new trick for your bike!

Tools You’ll Need

The type of tool you need depends entirely on your pedals. Some pedals have flats on the spindle (the metal part that screws into the crank arm) for a pedal wrench. These wrenches are typically thin and long, designed to fit into tight spaces.

Other pedals, often found on mountain bikes, have a hexagonal socket inside the end of the spindle. For these, you’ll need an Allen key (also called a hex wrench). The most common size for bike pedals is 6mm, but it’s wise to have a set handy just in case. You can find both pedal wrenches and Allen keys at any local bike shop or online.

Identifying Your Pedal Type

To figure out which tool to grab, inspect the pedal spindle. Look where the pedal attaches to the crank arm. Do you see a flat surface where a wrench can grip? If so, you’ll need a pedal wrench. If you see a hole that looks like it can fit a hexagonal bit, you’ll need an Allen key.

Most modern mountain bike pedals use the Allen key system. It’s a cleaner look and often allows for easier removal if you’re working on the bike from the side. Many brands, like Crankbrothers and Shimano, commonly use this design. Knowing this will save you time and frustration when you’re ready to get started.

The Removal Process: Step-by-Step

Once you have your tools and know the direction, it’s time to get to work. This is where patience and firm pressure are your best friends. Remember, these parts are often put on tight and can get seized over time, especially if they haven’t been removed for a while.

Preparing Your Bike

First, make sure your bike is stable. You don’t want it tipping over while you’re applying force. The easiest way is to place your bike in a bike stand. If you don’t have one, lean it against a sturdy wall or fence. Some people even have a friend hold it steady.

You’ll be applying a good amount of force. Ensure the crank arm you’re working on is positioned so you can push down with your body weight. Often, this means rotating the crank forward so the pedal is in the forward position. This allows you to use gravity and your body weight to your advantage.

Loosening the Drive-Side Pedal (Right Side)

Let’s start with the pedal on the right side of your bike, which is the drive-side. Remember, this one loosens counter-clockwise. If you’re using an Allen key, insert it firmly into the pedal spindle. If you’re using a pedal wrench, place it onto the flats of the spindle.

Now, apply steady, firm pressure in the counter-clockwise direction. You might need to push hard. If it doesn’t budge, a little bit of penetrating oil can help. Let it sit for 10-15 minutes. We found that this can make a surprising difference. After the soak, try again with firm, consistent pressure. Avoid jerky movements, which can strip the threads.

Loosening the Non-Drive-Side Pedal (Left Side)

Next up is the pedal on the left side, the non-drive-side. This pedal loosens in the *opposite* direction of what you might expect. It loosens clockwise. Yes, you read that right!

So, if you’re facing the bike from the left side, you’ll be turning the wrench or Allen key towards the front of the bike to loosen it. Insert your tool securely. Apply firm, consistent pressure in the clockwise direction. Just like the other side, don’t be afraid to use your body weight. If it’s stuck, a bit of penetrating oil can work wonders here too.

Dealing with Stuck Pedals

Sometimes, pedals can be incredibly stubborn. If you’ve tried everything and they won’t budge, it might be time for a more aggressive approach. Some mechanics suggest using a longer wrench for more leverage. Others recommend a gentle tap with a rubber mallet on the wrench handle to shock it loose. Always be careful not to damage the crank arm.

If you’re still struggling, it might be best to take it to your local bike shop. They have specialized tools and experience dealing with seized parts. They can often remove them without causing damage. We found that taking it to a pro is better than risking a costly repair to your crank arm.

Post-Removal Care and Cleaning

Once the pedals are off, don’t just toss them aside! Take a moment to inspect the threads on both the pedal spindle and the crank arm. You might see some old grease, dirt, or even rust.

It’s a good idea to clean these threads thoroughly. Use a degreaser and a brush or a clean rag. You can also use a small pick or a wire brush to gently remove any stubborn debris. Clean threads ensure that when you put new pedals on, they go in smoothly and securely. This step is often overlooked, but it’s vital for preventing future issues.

Here’s a quick checklist for your next pedal removal:

• Gather your tools (pedal wrench or Allen key).
• Confirm pedal thread direction (right side loosens CCW, left side loosens CW).
• Position the crank arm for leverage.
• Apply steady, firm pressure.
• Clean pedal and crank threads after removal.
• Apply new grease before reinstalling pedals.

Conclusion

You’ve now learned the essential steps to confidently remove your mountain bike pedals. Remember the key difference in loosening directions: righty-tighty, lefty-loosey doesn’t always apply! The drive-side pedal loosens counter-clockwise, while the non-drive-side pedal loosens clockwise. With the right tools and a bit of steady pressure, you can handle this maintenance task yourself. After removal, take the time to clean the threads to ensure a smooth reinstallation. Now you’re ready to tackle pedal maintenance like a pro, saving time and money on your bike upkeep. Your next step is to gather your tools and give it a try!

Frequently Asked Questions

What if my pedals are really stuck and won’t budge?

When pedals are stubborn, try applying a penetrating oil and letting it sit for about 15 minutes. Then, use a longer pedal wrench for better leverage or a gentle tap on the wrench handle with a rubber mallet. If they still won’t move, it’s best to seek help from your local bike shop to avoid damaging your crank arms.

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

Generally, no. Pedal wrenches are specifically designed to be thin and long to fit the tight space around the pedal spindle. A standard wrench is usually too thick and might not grip the pedal flats properly, increasing the risk of slipping and stripping the pedal or wrench. Always use a dedicated pedal wrench or the correct size Allen key.

Does it matter which way I turn the Allen key for mountain bike pedals?

Yes, it absolutely matters! For the drive-side pedal (right side), you’ll turn the Allen key counter-clockwise to loosen. For the non-drive-side pedal (left side), you’ll turn the Allen key clockwise to loosen. Always double-check this before applying force to avoid damaging your pedals or crank arms.

How do I know if I need a pedal wrench or an Allen key?

Inspect the end of the pedal spindle where it meets the crank arm. If you see flat surfaces that a wrench can grip, you’ll need a pedal wrench. If you see a hexagonal hole inside the end of the spindle, you’ll need an Allen key, typically a 6mm size for most mountain bike pedals.

Should I put grease on the pedal threads when I reinstall them?

Absolutely! Cleaning the threads is vital, and applying a fresh coat of grease before reinstalling your pedals is just as important. This prevents them from seizing in the future, making your next removal much easier. It also helps ensure a secure fit without over-tightening.
