4. Troubleshooting
Here are some common issues and their potential solutions:
- Flat Tire: Inspect the tire for punctures. If found, repair or replace the inner tube. Ensure the tire is properly seated on the rim before inflating.
- Gear Shifting Problems: If gears are not shifting smoothly, check the derailleur alignment and cable tension. Lubricate the chain and shifters.
- Brake Squeal/Ineffectiveness: Clean brake rotors and pads. Ensure pads are not worn out. Adjust brake cable tension for optimal performance.
- Loose Components: If you notice any wobbling or unusual noises, stop riding and inspect all fasteners, especially on the handlebars, seat post, and wheels. Tighten any loose parts.
