How We Calculate This
Single Speed Recommendations
The calculator suggests a chainring and sprocket based on terrain type:
- Flat: 48/16 (3.0 ratio) — faster cruising speed
- Mixed: 44/16 (2.75) — versatile all-rounder
- Hilly: 42/18 (2.33) — easier climbing
- Urban: 44/17 (2.59) — good stop-start ratio
