What This Calculator Measures
Plan cycling cadence targets using speed, gear ratio, and climb percentage.
By combining practical inputs into a structured model, this calculator helps you move from vague estimation to clear planning actions you can execute consistently.
This calculator estimates cadence targets from speed and gear inputs.
How to Use This Well
- Enter target speed and wheel size.
- Add gear ratio and cadence goal.
- Set climb percent and interval length.
- Review required cadence.
- Adjust gear ratio.
Formula Breakdown
Cadence = speed / (circumference x ratio)Worked Example
- 18 mph with 2.1m wheel, 3.2 ratio.
- Cadence around 86 rpm.
- 10 intervals per hour at 6 min.
Interpretation Guide
| Range | Meaning | Action |
|---|---|---|
| Below 80 | Low. | Use easier gear. |
| 80-95 | Balanced. | Efficient cadence. |
| 95-105 | High. | Strong tempo. |
| Above 105 | Very high. | Short efforts. |
Optimization Playbook
- Lower gear ratio: reduce cadence demand.
- Increase cadence goal: build efficiency.
- Manage climbs: adjust target speed.
- Use intervals: train cadence control.
Scenario Planning
- Baseline: current cadence goal.
- Higher climb: add 3%.
- Lower gear: reduce ratio by 0.3.
- Decision rule: keep cadence under 100 rpm.
Common Mistakes to Avoid
- Using wrong wheel size.
- Ignoring gear ratio.
- Overestimating target speed.
- Skipping climb adjustments.
Implementation Checklist
- Confirm wheel size.
- Set gear ratio.
- Define cadence goal.
- Plan intervals.
Measurement Notes
Treat this calculator as a directional planning instrument. Output quality improves when your inputs are anchored to recent real data instead of one-off assumptions.
Run multiple scenarios, document what changed, and keep the decision tied to trends, not a single result snapshot.
FAQ
How do I find wheel circumference?
Use manufacturer specs or measure tire roll.
What cadence is ideal?
Many riders target 80-95 rpm.
Does climb percent change cadence?
Yes, climbs often reduce cadence unless you shift.
