Question: what do you get when Formula One engineers turn their attention to bicycles? Answer: the jaw-dropping Caterham Duo Cali Limited Edition. We spotted the Duo Cali at the mammoth Eurobike trade show, where it instantly shone among a sea of identikit carbon fibre machines. The frame’s elegant silhouette, where the toptube flows seamlessly into the seatstays and the downtube swoops into the chainstays, is the result of a design philosophy which placed equal emphasis on performance and aesthetics
Such complex tube profiles require a carbon fibre mould made from 12 separate pieces and the frame is manufactured in collaboration with German firm ax-lightness. Caterham state a claimed weight of 1,200g so it’s far from the lightest frame on the market but engineering targets which demanded stiffness values of 90nm at the headtube and 60nm at the bottom bracket were easily met. The frame is dressed in equally beautiful components, with the Limited Edition equipped with Campagnolo Super Record EPS and Tune Airways carbon wheels for an eye-watering €15,000.
