✓ Specs checked against the manufacturer
Last checked 4 Sept 2026 against the manufacturer's own page . Caveat: Size 56 geometry row. Specialized states clearance as both 'up to 40mm' and '38c/40mm'; 40mm is recorded. Chainset is a 105 50/34 with an 11-36 cassette. Specialized calls this frame fender-ready but documents no rack mounts, so rack mounts are recorded as absent. Specialized prints no model year on this page; 2026 reflects the current UK line-up as listed.
