Aero Weight Calculator

Stop guessing which wheel upgrade actually makes you faster. Our physics-based calculator runs the real math — aerodynamic drag, gravity forces, rolling resistance — across three scenarios simultaneously. Enter your weight, power, and climb data, and get a verdict in seconds: does weight or aero win on your specific gradient?
