✓ 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: Geometry is the size 56 column of Cannondale's Topstone Carbon chart. Cannondale publishes no complete-bike weight, so weightKg is an estimate from the build. Clearance is the 52mm Cannondale states for a 1x build; a 2x build is limited to 45mm and the fork takes 56mm. The frame has a removable mudguard bridge and the fork has mudguard mounts; Cannondale documents no rack mounts, so those are recorded as absent.
