✓ Specs checked against the manufacturer
Last checked 4 Sept 2026 against the manufacturer's own page . The weightfigure is our estimate — the manufacturer publishes none. Caveat: Size 56cm geometry row from Dolan's own chart; Dolan prints stack as 589 and reach as 384.9, rounded to 385 here. Dolan builds this bike to order: the £1,199.99 price and the 50/34 chainset, 11-34 cassette and 700x28c Vittoria Zaffiro tyres recorded here are the options Dolan has pre-selected in its configurator, and the price is rounded to £1,200. Clearance is Dolan's stated 35mm maximum, which drops to 32mm with full-length mudguards fitted. Dolan publishes no complete-bike weight, only a 2.2kg frame and fork at 54cm, so the 9.8kg shown is our estimate. Dolan prints no model year; 2026 reflects the current catalogue listing.
