✓ 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 Tiagra 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. This build uses Future Shock 3.1, not the 3.2 of the dearer trims. Specialized prints no model year on this page; 2026 reflects the current UK line-up as listed.
