My Fenders Won't Stay In Place - Troubleshooting

If your fenders are slipping, rotating, or won't stay in position, don't worry—this is usually an easy fix. Here are the most common causes and solutions.

Common Issues and Solutions

Issue 1: Fender Rotates Around the Frame Tube

Cause: Zip ties aren't tight enough, or there aren't enough attachment points.

Solutions:

• Use pliers to tighten zip ties—hand-tightening alone often isn't sufficient, especially for Phantom fenders
• Add more zip ties at different angles to create multiple points of resistance
• Use all included zip ties—don't skip attachment points thinking fewer will suffice

Issue 2: Fender Slides Up or Down

Cause: Smooth frame tubes allow zip ties to slip under vibration.

Solutions:

• Add a rubber strip (cut from an old inner tube) between the zip tie and frame. This adds friction and prevents sliding
• Position zip ties at frame joints or where tubes change diameter to create a natural stopping point
• Use two zip ties side-by-side at each attachment point for added grip

Issue 3: Fender Touches the Tire

Cause: Fender mounted too close to the tire, or has shifted during riding.

Solutions:

• Reposition with more clearance—aim for 1-2 inches minimum between fender and tire
• Check zip tie tightness and re-secure if needed
• Ensure proper angle—the fender should follow the curve of the wheel, not angle toward it

Issue 4: Zip Ties Keep Breaking

Cause: Zip ties may be over-tightened during installation, creating weak points, or exposed to extreme UV/cold.

Solutions:

• Tighten firmly but don't over-crank—zip ties should be snug, not stretched to their limit
• Use fresh, high-quality zip ties if yours have been stored in sunlight or extreme cold
• Replace with UV-resistant zip ties if you store your bike outdoors

Issue 5: Fender Works Loose After Riding

Cause: Normal vibration can cause zip ties to settle; this is common after the first few rides.

Solutions:

• Re-tighten or replace zip ties after your first 2-3 rides
• Check attachment points regularly as part of your pre-ride routine
• Carry spare zip ties on long rides for field adjustments

Prevention Tips

• Use all the zip ties included with your fenders
• Pliers are essential for Phantom fenders—don't skip this step
• Check your fenders after your first few rides and tighten as needed
• For maximum security, attach at multiple points and angles
