✓ Specs checked against the manufacturer

Last checked 4 Sept 2026 against the manufacturer's own page . Caveat: Chainset is a Dura-Ace 50/34 power meter with an 11-34 cassette. Size 56 geometry row. Specialized states clearance as both 'up to 40mm' and '38c/40mm'; 40mm is recorded. Specialized calls this frame fender-ready but documents no rack mounts, so rack mounts are recorded as absent. Weight is Specialized's claimed figure for a production painted frame in size 56. Specialized prints no model year on this page; 2026 reflects the current UK line-up as listed.
