Skill Learning Path: From Zero to Self-Sufficient

Stage One: Basic Survival Skills (Learning time: 1-2 weeks)

These are skills every cyclist should have — they let you rescue yourself when problems happen on the road:

1. Changing and Patching Inner Tubes

This is the most basic and most important skill. Practice steps:

Money-saving tip: Regular cleaning can extend parts life by 30-50%, indirectly saving significant replacement costs.

Shifting problems are the most common issue — learn to adjust limit screws and cable tension:

• Front derailleur adjustment
