Cadence Calculator — RPM for Target Speed
Calculate the cadence needed to reach a target speed in any gear.
How We Calculate This
Cadence Formula
Cadence (RPM) = Speed (mm/min) / Development (mm/rev)
Where Development = Gear Ratio x Wheel Circumference. This is the inverse of the speed-in-gear calculation.
Frequently Asked Questions
For efficient road cycling, aim for 80-100 RPM. Lower cadences (60-80) use more muscular strength, higher cadences (90-110) rely more on cardiovascular fitness.
Yes. Above 110-120 RPM, most riders start bouncing on the saddle and wasting energy. The sweet spot for most is 85-95 RPM.
Practice spinning drills: ride in an easy gear at 100-110 RPM for 5-minute intervals. Over time, higher cadences become more natural and efficient.
