In the picture
- Chain on the largest rear cog: easier pedalling for a steep uphill.
- Chain on a middle rear cog: steady pedalling on flat ground.
- Chain on the smallest rear cog: more speed for a downhill.
Examples
- Riding to school up a steep street, shift to a larger rear cog.
- On a flat bike path, keep a middle rear cog for a comfortable rhythm.
Key takeaways
- A larger rear cog makes pedalling easier but slower.
- A smaller rear cog makes pedalling harder but faster.
