✓ Specs checked against the manufacturer

Last checked 4 Sept 2026 against the manufacturer's own page . Caveat: Size 56 geometry row, taken from Specialized's frame stack and frame reach rows rather than their stack/reach-to-stem rows. Chainset is 52/36 with an 11-30 cassette, the narrowest gearing range in this line-up. Specialized documents no mudguard or rack mounts, so both are recorded as absent. Specialized prints no model year on this page; 2026 reflects the current UK line-up as listed.
