Why You Might Need to Remove Your Pedals
Pedals aren’t just there to push your bike; they’re often the first point of contact with your power and the trail. Knowing how to remove and reinstall them properly is crucial for several reasons.
You might need to remove your pedals for easier transport, especially when loading your mountain bike onto a car rack or packing it into a bike bag for a flight. This simple step can prevent damage and make handling much more manageable.
Upgrading your pedals is another common reason. Maybe you’re switching from flat pedals to clipless for better power transfer on climbs, or perhaps your old pedals are simply worn out after countless miles and muddy adventures. Swapping them out can breathe new life into your ride.
Finally, routine maintenance often requires pedal removal. Cleaning and regreasing pedal threads helps prevent seizing, extends component life, and ensures smooth operation. It’s a small task that pays big dividends in the long run.
Gathering Your Gear: Essential Tools for Pedal Removal
Before you dive in, gather the right tools. Using the correct gear makes the job easier and prevents damage to your bike’s components. Don’t try to force it with the wrong wrench; you’ll regret it.
Here’s what you’ll typically need:
- Pedal Wrench: This is your best friend for pedal removal. A good pedal wrench is thin, long, and offers excellent leverage. Look for one with a 15mm opening.
- Hex Keys (Allen Wrenches): Many modern pedals use an 8mm or 6mm hex key that inserts from the back of the crank arm. Check your pedals to see which type you have.
- Grease or Anti-Seize Compound: Essential for reinstallation to prevent future seizing and ensure smooth threading.
- Shop Rags: Keep things clean, especially if you’re dealing with old grease and grime.
- Work Stand (Optional but Recommended): A bike repair stand makes the job much easier by holding your bike securely. If you don’t have one, prop your bike against a sturdy wall.
- Gloves: Protect your hands from grime and potential scrapes.
- Penetrating Oil (e.g., WD-40, PB Blaster): For those notoriously stubborn, seized pedals.
Having these items ready before you start will ensure a smooth process. You don’t want to be halfway through and realize you’re missing a critical tool.
Prepping Your Ride: Safety and Setup First
Preparation is key to a successful, safe, and frustration-free job. Don’t skip these initial steps; they set you up for success.
First, secure your bike. If you have a bike stand, mount your bike firmly. This keeps it stable and at a comfortable working height. If not, lean it against a sturdy object or have a friend help stabilize it. A wobbly bike makes pedal removal much harder and riskier.
Next, orient your crank arms correctly. Position the pedal you’re working on so the crank arm is pointing forward, parallel to the ground. This gives you the best leverage and keeps your knuckles safe from hitting the chainring or frame.
Finally, clean around the pedal spindle where it meets the crank arm. Years of dirt and grime can hide the wrench flats or hex key receiver, and make it harder to get a good grip. A quick wipe-down can save you a lot of headache.
How to Remove Bike Pedals: Step-by-Step for Left & Right
This is where the magic happens. Remember, the key difference between the left and right pedals is their threading direction. This is a common point of confusion, so pay close attention.
Understanding Pedal Thread Direction
This is perhaps the most important detail to remember when learning how to remove bike pedals. Pedals are designed to self-tighten as you ride, preventing them from unscrewing themselves. This means they have opposing thread directions.
- Right Pedal (Drive Side): This pedal has standard right-hand (clockwise) threads. To loosen it, you turn the wrench counter-clockwise.
- Left Pedal (Non-Drive Side): This pedal has reverse or left-hand (counter-clockwise) threads. To loosen it, you turn the wrench clockwise.
A simple way to remember this is: “Forward to loosen, backward to tighten.” When the crank arm is forward, imagine pushing the wrench towards the back of the bike to loosen both pedals.
Removing the Right Pedal (Drive Side)
The right pedal is on the same side as your chainring and derailleur. This is often referred to as the drive side.
- Position the Crank: Rotate the right crank arm so it points forward, parallel to the ground, or slightly forward of that.
- Attach the Wrench: If using a pedal wrench, fit the 15mm open end securely onto the wrench flats of the pedal spindle. If using a hex key, insert it firmly into the back of the crank arm.
- Apply Force: For the right pedal, you need to turn the wrench counter-clockwise to loosen. Position yourself so you can push down on the wrench (or pull up, depending on your angle) with good leverage. Think about pushing the wrench towards the rear of the bike.
- Break it Loose: Often, the initial turn is the hardest. You might hear a “crack” as the threads break free – this is normal. Once it loosens, you can usually spin it off by hand.
- Unscrew: Continue turning counter-clockwise until the pedal detaches completely from the crank arm.
Removing the Left Pedal (Non-Drive Side)
The left pedal is on the opposite side of your chain. This is the non-drive side.
- Position the Crank: Rotate the left crank arm so it points forward, parallel to the ground, or slightly forward of that.
- Attach the Wrench: Fit your pedal wrench onto the wrench flats or insert the hex key into the back of the crank arm.
- Apply Force: For the left pedal, you need to turn the wrench clockwise to loosen. Again, think about pushing the wrench towards the rear of the bike. This is the opposite direction of the right pedal!
- Break it Loose: Apply firm, steady pressure. Once it breaks free, it should spin relatively easily.
- Unscrew: Continue turning clockwise until the pedal comes completely off the crank arm.
Always support the bike and ensure you have stable footing when applying force. A slip can lead to injury or damage.
Tackling Stubborn Pedals: Pro Tips for Seized Threads
Sometimes, despite your best efforts, a pedal just won’t budge. Rusted threads, old grease, or simply being overtightened can cause a pedal to seize. Don’t panic; here are some pro tricks to help you out.
Using Penetrating Oil
If a pedal is truly stuck, penetrating oil is your first line of defense. Apply a generous amount to the threads where the pedal spindle enters the crank arm. Let it sit for at least 15-30 minutes, or even longer for seriously corroded pedals. Tap the pedal spindle lightly with a rubber mallet to help the oil wick into the threads. Reapply and wait again if needed.
Leverage is Your Friend
A longer pedal wrench provides more leverage. If your standard wrench isn’t cutting it, consider using a cheater bar – a length of pipe slipped over the handle of your wrench. This significantly increases your leverage, but be careful not to overdo it and strip the threads or damage the crank arm.
The “Third Hand” Technique
For hex key pedals, this trick can be a lifesaver. Insert the hex key into the pedal, then position the crank arm forward. Place the hex key in the correct loosening direction (counter-clockwise for right, clockwise for left). Now, use your foot to stand on the opposite crank arm, pushing it down while simultaneously pushing down on the hex key. This uses your body weight and the crank arm’s rotation to create immense loosening force.
Heat (Use with Extreme Caution!)
As a last resort, gentle heat can sometimes expand the crank arm enough to release a seized pedal. Use a heat gun or even a hairdryer, applying heat evenly around the pedal spindle for a minute or two. Be extremely careful not to overheat carbon fiber components or paint. This is a technique best left to experienced mechanics if you’re not confident.
If you’ve tried these methods and the pedal still won’t budge, it might be time to take your bike to a professional mechanic. They have specialized tools and more experience with extreme cases.
Reinstalling Pedals: A Quick Guide to Proper Torque
Now that you know how to remove bike pedals, putting them back on correctly is just as important. Proper reinstallation ensures safety, prevents damage, and makes future removal easier.
Clean and Grease the Threads
Before installing any pedal, always clean both the pedal threads and the crank arm threads. Use a rag to wipe away old grease, dirt, and any metal shavings. Once clean, apply a fresh layer of bicycle-specific grease or anti-seize compound to the pedal threads. This prevents corrosion, makes installation smoother, and ensures easy removal next time.
Start by Hand
Always start threading the pedal into the crank arm by hand. This helps prevent cross-threading, which can permanently damage your crank arm. Remember the thread directions:
- Right Pedal: Turn clockwise to tighten.
- Left Pedal: Turn counter-clockwise to tighten.
If you feel any resistance when hand-threading, stop immediately. Back the pedal out, check the threads for damage, and try again. It should spin in smoothly for several rotations.
Tighten with a Wrench
Once the pedal is finger-tight, use your pedal wrench or hex key to snug it down. Pedals need to be tight, but not overtightened. The typical torque specification for bike pedals is around 35-40 Nm (Newton-meters).
If you have a torque wrench, use it for precision. If not, tighten firmly with your pedal wrench. A good rule of thumb is “snug plus a quarter turn.” Don’t stand on the wrench, but apply significant hand pressure.
Overtightening can strip threads, making future removal impossible. Undertightening can cause the pedal to loosen while riding, potentially damaging the crank arm or leading to a crash.
Frequently Asked Questions About Bike Pedal Removal
What’s the difference between left and right pedal threads?
The right pedal (drive side) has standard right-hand threads, meaning you loosen it by turning counter-clockwise. The left pedal (non-drive side) has reverse or left-hand threads, meaning you loosen it by turning clockwise. This design prevents them from unscrewing while you ride.
Can I use a regular adjustable wrench instead of a pedal wrench?
While an adjustable wrench might fit, it’s not recommended. Its jaws can slip, stripping the pedal flats or damaging your knuckles. A dedicated pedal wrench is thinner, stronger, and designed for the leverage needed to safely remove bike pedals. Invest in the right tool for the job.
My pedals are stuck, and I can’t get them off. What should I do?
First, try applying penetrating oil and letting it soak in. Increase your leverage with a longer wrench or a cheater bar. For hex key pedals, try the “third hand” technique by pressing down on the opposite crank arm while pushing the hex key. If all else fails, a bike shop can often remove them with specialized tools.
Do I need to grease pedal threads before reinstallation?
Yes, absolutely! Applying a thin layer of grease or anti-seize compound to the pedal threads before reinstallation is crucial. It prevents corrosion, makes installation smoother, and ensures you can remove the pedals easily next time without them seizing up.
How tight should I tighten my bike pedals?
Pedals need to be tight, typically to around 35-40 Nm. If you don’t have a torque wrench, tighten them firmly with a pedal wrench – “snug plus a quarter turn” is a good manual guide. Avoid overtightening, which can strip threads, and undertightening, which can cause the pedal to loosen during a ride.
Conclusion: Master the Wrench, Master Your Ride
Learning how to remove bike pedals is a fundamental skill that every rider and DIY mechanic should have in their toolkit. It’s a simple process once you understand the crucial difference between left and right-hand threads and apply the right techniques.
By following these steps, you’ll be able to swap pedals for different riding conditions, pack your bike for travel, or perform essential maintenance with confidence. Remember, patience and the correct tools are your best allies.
Don’t be afraid to get your hands dirty and understand the mechanics of your machine. The more you know, the more capable you become, whether you’re fixing a flat on the trail or prepping your rig for its next off-road adventure. Keep those wheels spinning, and enjoy the ride!
