Configurable bike builder, frame size × component × wheelset × color, can Magento handle Project-One depth?

Yes. Trek Project One ships ~12 trillion theoretical combinations on a single frame. The reality is the customer picks one combo at a time, and the platform needs to (a) show valid combinations, (b) price-recalculate live, (c) check stock per combination, (d) save the build to wishlist / cart.

The Magento model:

• Configurable product per frame model (e.g. Madone SLR 9). Simple products per valid frame-size + paint combo. EAV attributes for frame size (with stack/reach numbers), color, paint scheme.
• Custom configurator UI layer on PDP, built in Alpine.js (Hyvä-native). Pulls available components from a sibling catalog filtered by frame compatibility. Live-recalculates price using Magento price API.
• Compatibility rules engine behind the configurator, JSON match-table per frame: which crank lengths, which derailleur hangers, which brake mount standards, which wheelset axle widths (12mm thru-axle vs 100mm QR).
• Build-to-cart serialization, full build saved as a single configurable cart line with metadata; the LBS receives a build sheet with every component listed.

Cost to build: $8k, $20k for a Project-One-class configurator, depending on combination depth. Cheaper alternative: 3rd-party configurator like Roomle or Configure One via Magento extension ($300, $800/mo).
