Identity

Canonical configuration: Specialized | PORTO 4.0 NB | 2026
Confidence: medium

• brand exact (Specialized)
• model normalized to "porto 4.0 nb"
• groupset family unidentified on every listing
• GTIN match (0888818878413)
• listings state different model years (2025, 2026); the shared manufacturer barcode says they are one SKU and is trusted over the year fields
• 4 listings across 3 retailers
• downgraded to medium: listings disagree on suspension: full vs none
• conflict: suspension: full vs none

Provenance — why we believe each fact

Warnings

• info wheel-size-varies-by-frame-size — the row states more than one wheel size ("24/20"), so the wheel size of the bike in a given frame size is not established. Recorded as unknown rather than picking one.
• info single-size-only — Only one size is in stock (33 cm).
• high groupset-unknown — Groupset could not be established.
