Removing bicycle pedals requires the correct tools, proper orientation, and applying force in the right direction to avoid damage.
Understanding Bicycle Pedal Threads
Bicycle pedals aren’t just screwed on randomly; they have specific threading that ensures they stay tight while riding. The right pedal has a standard right-hand thread, which means it tightens clockwise and loosens counterclockwise. Conversely, the left pedal has a left-hand (reverse) thread, so it tightens counterclockwise and loosens clockwise.
This design prevents pedals from unscrewing themselves during use because of the natural forces applied while pedaling. Grasping this concept is crucial before attempting removal because turning the pedals in the wrong direction can damage threads or make removal impossible.
Right vs Left Pedal Thread Direction
| Pedal Side | Thread Type | Loosening Direction |
|---|---|---|
| Right (Drive Side) | Standard (Right-Handed) | Counterclockwise (Lefty Loosey) |
| Left (Non-Drive Side) | Reverse (Left-Handed) | Clockwise (Righty Loosey) |
Knowing which side you’re working on saves time and prevents frustration.
The Tools You’ll Need
Having the right tools makes all the difference. Most pedals require either a 15mm pedal wrench or an appropriately sized Allen key (hex wrench), often 6mm or 8mm, depending on your bike model.
A pedal wrench is a thin, long-handled spanner designed specifically for this task. It fits snugly onto the flats of the pedal axle and provides leverage for loosening tight pedals.
Alternatively, some modern pedals have an internal hex socket at the end of the spindle near the crank arm. For these, an Allen key inserted into this socket allows removal without risking damage to pedal flats.
Occasionally, penetrating oil like WD-40 helps loosen stubborn pedals that have been tightened for years or exposed to corrosion.
Step-by-Step Pedal Removal Process
Step 1: Position Your Bike Securely
Place your bike either upside down resting on its saddle and handlebars or use a sturdy bike stand if available. Stability is key to applying force safely without slipping or causing injury.
Make sure you have enough room to maneuver your tools freely around each pedal.
Step 2: Identify Each Pedal’s Threading
Recall that the right pedal loosens by turning counterclockwise, while the left pedal loosens by turning clockwise. Confirm which side you’re starting with so you don’t accidentally tighten instead of loosen.
If uncertain, stand facing your bike’s drivetrain side (right side). The pedal closest to you is right-side; opposite is left-side.
Step 3: Apply Penetrating Oil if Needed
If pedals feel stuck or rusty, spray penetrating oil where the pedal threads into the crank arm. Let it soak for about 10-15 minutes to break down corrosion and ease removal effort.
This step can save you from stripping threads or damaging crank arms later on.
Step 4: Insert Your Tool Correctly
- If using a pedal wrench: Place it firmly on the flat surfaces of the pedal spindle closest to where it meets the crank arm.
- If using an Allen key: Insert it fully into the hex socket at the end of the spindle.
Make sure your tool is seated properly to prevent slipping off during application of force.
Step 5: Loosen Each Pedal Using Proper Direction
- Right Pedal: Push or pull your tool counterclockwise.
- Left Pedal: Push or pull your tool clockwise.
Sometimes pedals can be very tight due to factory torque specs or years of use. Use steady pressure rather than jerking motions to avoid injury or damage.
If needed, use your body weight carefully on longer wrenches for extra leverage but avoid sudden forceful bursts that might strip threads.
Step 6: Unscrew Pedals by Hand After Loosening
Once loosened enough with your tool, finish unscrewing by hand. This reduces risk of cross-threading when removing fully and allows better control over final detachment.
Handle pedals gently since some models contain delicate bearings inside that can be damaged if dropped hard.
Troubleshooting Stubborn Pedals
Sometimes pedals refuse to budge despite correct technique. Here are some tips:
- Add More Penetrating Oil: Reapply oil and allow more time—sometimes hours—to penetrate rusted threads deeply.
- Tapping Method: Lightly tap around where pedal meets crank arm with a rubber mallet to break corrosion bonds without damaging metal.
- Use Heat Cautiously: In extreme cases, warming up crank area with a heat gun may expand metal slightly and ease removal but be extremely careful not to damage paint or components.
- Avoid Damaging Threads: Never force pedals at odd angles; this risks stripping threads inside crank arms which are expensive to repair.
- If All Else Fails: Seek professional help instead of risking permanent damage by excessive force.
Caring for Your Crank Arms and Pedals After Removal
Once pedals come off successfully, take time to inspect both crank arms and pedal spindles:
- Clean Threads Thoroughly: Remove dirt, grime, old grease, and any corrosion from both parts using a rag and brush.
- Add Fresh Grease Before Reinstallation: Apply quality bicycle grease evenly on threads before putting pedals back on later. This prevents seizing and eases future removals.
- Check for Wear or Damage: Look for bent spindles, stripped threads, cracks in crank arms, or damaged bearings in pedals. Replace faulty parts as needed.
- Tighten Correctly When Reinstalling: Use proper torque specifications from manufacturer guidelines — usually between 30-40 Nm — so pedals stay secure without over-tightening.
The Importance of Correct Technique and Safety Tips
Removing pedals might seem straightforward but requires care:
- Avoid Injuries: Tools slipping off can cause cuts or bruises. Maintain firm grips and wear gloves if necessary.
- No Shortcuts: Using improper tools like adjustable wrenches risks rounding off flats making future removals difficult.
- Keeps Components Intact:
- Saves Time & Money:
The Role of Different Types of Pedals in Removal Difficulty
Pedals come in various designs affecting how easy they are to remove:
- Cage Pedals with Flats: These usually have visible flats suitable for standard wrenches making removal straightforward.
- Lighter Clipless Pedals:
- Bearing Quality & Seals:
- Bolt-on vs Thread-in Models:
A Quick Comparison Table: Tools & Methods Summary
| Tool/Method | Description & Use Case | Main Advantage(s) |
|---|---|---|
| Sized Pedal Wrench (15mm) | A thin wrench designed specifically for gripping pedal flats; ideal for traditional cage-style pedals with visible flats near cranks. | Makes applying torque easier without damaging parts; fits most common pedal sizes precisely. |
| Allen Key (6mm/8mm) | A hex wrench inserted into internal socket at end of spindle; common with clipless pedals lacking external flats. | Keeps tool engagement secure; reduces risk of rounding flats compared to open wrenches; compact size helps working space constraints. |
| Pentrating Oil & Mallet Taps | Chemical loosener sprayed onto stuck threads combined with gentle tapping breaks rust bonds preventing thread damage. | Eases stubborn removals safely without excessive force; preserves component integrity. |
Avoiding Common Mistakes That Can Ruin Your Ride Parts
Missteps happen frequently during pedal removal:
- Mistaking Thread Direction: Turning left instead of right (or vice versa) only tightens instead of loosening making things worse.
- No Tool Engagement: Poorly seating wrenches causes slippage damaging flats leading to rounded edges impossible for future tools.
- No Lubrication: Dried grease or rust locks threads tightly making brute force necessary which risks stripping.
- No Stability: Bikes shifting during effort cause loss of control increasing injury risk.
- Straight Pulls Instead Of Turning: The only way out is twisting—pulling straight won’t budge threaded parts.
