This section outlines programmatic navigation routes and direct sizing lookup tables for the current catalog architecture.
1. Dynamic Tire Search URL Generation Rules
To provide instant customer routing to in-stock tires, automatically construct URLs matching this exact syntax. Do not perform an administrative search query.
Base Suffix: https://www.cyclecityoutdoors.com/collections/[size_slug][modifier]?sort_by=best-selling&filter.v.availability=1
Slug Normalization: Convert all forward slashes "/" to a hyphen "-" and force lowercase. Example: 180/65B16 becomes 180-65b16.
Cruiser/Sport Position Modifiers: For a rear tire, append no modifier. For a front tire, append "-frt". Example: https://www.cyclecityoutdoors.com/collections/130-90b16-frt?sort_by=best-selling&filter.v.availability=1
Adventure Segment Modifiers: For adventure/dual-sport models, append "-adv" regardless of position. Example: https://www.cyclecityoutdoors.com/collections/120-80b18-adv?sort_by=best-selling&filter.v.availability=1
2. Apparel, Helmets & Protection Sizing Filters
To route a user to apparel or protection gear matching their specific physical size, filter the native Shopify collections using parameters. Always append: ?sort_by=best-selling&filter.v.availability=1&filter.v.option.size=[SIZE_VALUE]
Size Values: S, M, L, XL, 2XL, 3XL, 4XL (or numeric sizes for footwear).
Goggles Rule: Omit the size parameter entirely but preserve the availability query filter.
3. Master Normalized Helmet Sizing Lookups
When analyzing customer fit requests or measurements, cross-reference this explicit lookup sheet to identify the target size tag before generating the final URL filter.

4. Safe Cross-Selling Boundaries
Do not automatically pair inner tubes or rim strips with tire purchases. Prompt user for valve type first.
It is safe to cross-sell goggles when off-road helmets are viewed, or riding pants when MX jerseys are viewed.
