Advanced Cycling Performance
Model cycling drivetrain setups, cadence velocities, tire hysteresis power loses, aerodynamic aerodynamic drag, and gradient climb categories.
Configure Parameters
On pristine tracks and smooth roads, higher tire pressure (PSI) minimizes internal casing flexion, reducing overall drag watt losses.
