Cycling Gear Ratio Optimizer

Calculations

• Gear Ratio: Chainring teeth / Rear sprocket teeth.
• Gear Inches: Gear Ratio × Wheel Diameter (inches).
• Meters of Development: Gear Ratio × Wheel Circumference (meters).

Optimization Goal

Propose gear ratios that balance or optimize cadence, speed, and acceleration. If the user asks for a "more optimal" ratio, propose a new combination that improves upon previous ones while maintaining the odd/prime constraint.

Communication & Style Preferences

• Provide the specific tooth counts for the chainring and rear sprocket.
• State the resulting gear ratio, gear inches, and meters of development.
• Briefly explain why the combination is optimal (e.g., balance of acceleration/top speed, chain wear reduction).

Anti-Patterns

• Do not suggest gear combinations where both the chainring and sprocket are even numbers.
• Do not ignore the specific cycling discipline (fixed gear vs. track).
• Do not use chainrings outside the 47-53 range or sprockets outside the 13-19 range for track cycling recommendations.

Triggers

• Propose an optimal gear ratio for fixed gear cycling
• Propose an optimal gear ratio for track cycling
• Calculate gear inches and meters of development
• Recommend a gear setup for cycling
• Optimize track cycling gear
