Disclaimer: While this article provides general troubleshooting tips, it may not cover all issues. If you encounter a problem that is not addressed here, or if you are unsure about how to perform a specific repair, it is recommended to consult a professional bicycle mechanic.
Flat Tires
- Cause: Punctures from road/trail debris such as thorns, nails, or glass.
- Solution:
- Remove the wheel from the bicycle.
- Locate the puncture by inflating the tire and listening for hissing.
- Use a tire lever to remove the tire from the rim.
- Examine the tire for the puncture.
- Remove the punctured tube and insert a new one.
- Reinstall the tire on the rim, ensuring it is properly seated.
- Inflate the tire to the recommended pressure.
Chain Issues
- Cause: Chain slippage, stretching, noise, or excessive wear.
- Solution:
- Chain slippage: Adjust the derailleur tension or ensure proper gear alignment so the chain is properly engaging with the gears.
- Chain stretching: Measure the chain length to determine if it needs replacement. If it is stretched beyond the manufacturer's specifications, replace it.
- Noise: Can be reduced by cleaning and adding lubricant, or ensuring derailleurs are properly aligned.
- Excessive wear: Clean and lubricate the chain regularly to prevent premature wear. If it is excessively worn, replace it.
Brake Problems
- Cause: Worn brake pads, misaligned brakes, or cable issues.
- Solution:
- Worn brake pads: Inspect the brake pads for wear. Replace them if they are worn down to the backing.
- Misaligned brakes: Adjust the brake calipers to ensure they are centered on the rim or rotor.
- Cable issues: Check the brake cables for fraying or corrosion. Replace them if necessary.
Gear Shifting Problems
- Cause: Misadjusted derailleurs, worn gears, or chain issues.
- Solution:
- Misadjusted derailleurs: Adjust the derailleur limits and tension to ensure proper shifting.
- Worn gears: Inspect the gears for excessive wear. Replace them if necessary.
- Chain issues: Ensure the chain is clean and lubricated. Replace it if it is stretched or excessively worn.
Wheel Wobble
- Cause: Bent rim, loose/broken spokes, or improper wheel assembly.
- Solution:
- Bent rim: If the rim is noticeably bent, it may need to be replaced or trued.
- Loose spokes: Tighten any loose spokes using a spoke wrench.
- Improper wheel assembly: If the wheel is not properly trued, it may need to be taken to a professional for adjustment.
