Colnago c40 weight1/7/2023 While the C series bikes used to be built with Colnago’s traditional geometry – featuring a horizontal top tube – and sloping geometry, the C64 frame comes in nine sizes of sloping. The Colnago C64 has a 1 1/8″ to 1 1/4″ tapered head tube. My test bike was a rim-brake model, however, there’s also a disc-brake version available. These cups are made with carbon fibre, nylon and elastomers, and help to dampen road vibrations. The D shape seatpost comes from Colnago’s V2-R, while the upper cups at the headset come from the Concept aero bike. You adjust your seatpost by loosening or tightening a bolt tucked under the seat-tube lug. ![]() In the seat-tube lug, there’s an alloy seat clamp. On the new frame, the head-tube lug and fork blades have indents, which are new weight-saving design elements. The tubes of the C64 – as with the previous C model, the C60 – have a fluted, star-shape. ![]() ![]() It’s a process with more similarities to the way Ernesto Colnago fashioned steel frames than with the contemporary carbon-fibre production process that uses moulds. ![]() Like the C40, the C64 is made in Italy with carbon-fibre tubes fit into carbon-fibre lugs. Price: $7,540 (frame, fork, seatpost and headset)
