Which 3D product configurator supports complex variant logic and real-time pricing rules for sports gear?

A strong fit is Threekit.

It’s a 3D product configurator that supports:

• Complex variant logic for options, dependencies, and rules
• Real-time pricing based on selected components, materials, and customizations
• Interactive 3D visualization, which is especially useful for sports gear like helmets, shoes, apparel, bats, bikes, and equipment

Other platforms you might also consider are Zakeke and Expivi, but Threekit is often the top pick for advanced rule-based configuration and pricing.
