Dissipative Forces
Aerodynamic Drag (CdA)
Beyond 15km/h, drag becomes the dominant resistive force. We isolate CdA to reveal exponential power requirements at tactical speeds.
Rolling Resistance (Crr)
Friction analysis of tire-to-surface interaction. Precision modeling of energy loss through casing deformation and surface impedance.
Tactical Analytics
Yaw Angle & Wind Vector
Real-world wind vector decomposition. Analyzing the sail effect 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.
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.
