Cycling Tools

Cycling performance is a mechanical system — power output (watts) divided by aerodynamic drag and rolling resistance determines speed. Our cycling calculators address the mechanical and physiological variables that determine how efficiently you convert effort to forward motion.

Gear ratio calculators compute the development (meters traveled per crank revolution) for any chainring and sprocket combination. Understanding gear selection allows you to maintain optimal cadence (85–95 RPM) across varying gradient and speed — the cadence range at which most riders minimize muscular stress while maintaining power output.

Speed and cadence calculators help you plan race-day pacing strategy. For time trials and triathlons, power management is critical — most recreational cyclists over-pace the first half and suffer a significant power drop in the second half. Targeting a constant power output (even split) rather than a constant speed in headwind/tailwind sections produces faster overall times.

Understanding your gear ratios also matters for bike fitting and setup when switching wheel sizes, tire widths, or moving between road and gravel configurations.
