✓ 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 claimed weight is higher than the cheaper Expert build because of the deeper wheels and wider tyres. 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.
