The Cost of Speed
Quantifying the exact exchange rate between metabolic output and kinetic velocity.
Dissipative Forces
Aerodynamic Drag (CdA)
Beyond 15 km/h, aerodynamic drag becomes the dominant resistive force. We isolate CdA to reveal exponential power requirements at tactical racing speeds.
Rolling Resistance (Crr)
Friction analysis of tire-to-surface interaction. Precision modeling of energy loss through casing deformation, tire pressure, and surface impedance.
Tactical Analytics
Yaw Angle & Wind Vector
Real-world wind vector decomposition. Analyzing apparent wind velocity and increased cross-sectional drag in crosswind environments.
Transition Tax
Calculating the power debt incurred from static time in transition. Quantifying the wattage required to neutralize tactical gaps over remaining distance.
Premium solvers
Measure your real CdA from ride files
Calibrate CdA from power rides, plan courses with your physics, or test velodrome setups in Track Lab.
