Standing Start Calculator

Compare two race setups using your own standing-start performance.

1. Your current start

Use a repeatable timing split. This sets the rider's starting ability.

Complete bike, including the current wheels.

2. Test a change

Change only what you want to compare. Everything else starts matched to the current setup.

Use -0.5 for a 500 g saving. Wheel weight updates automatically.
Advanced settings

Crank length changes are modelled during the opening acceleration at the rider's existing pedal-force capability; no automatic aerodynamic bonus is assigned. Race-wheel selections only. CRR and timed-event helmet factors match the pursuit ready reckoners. For Team Sprint Rider 1, the Pista Control tubular and Continental Sprinter receive a separate rear-tyre launch-grip estimate; their normal CRR remains in the calculation.
