✓ 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 Synapse Carbon chart. Cannondale publishes no complete-bike weight, so weightKg is an estimate from the build. Clearance is recorded as the 42mm rear maximum Cannondale states; the fork takes 48mm. Frame and fork carry mudguard mounts; Cannondale documents no rack mounts, so those are recorded as absent.
