An update to the popular C60 model and the latest in a long line of C-model framesets, the C64 retains the carbon-lugged design that has become synonymous with the brand.
A slightly wider fork on the C64, combined with direct-mount brakes front and rear allow for tyre clearances of 28mm on Costa's new bike, and while the former world champion ran 25mm Vittoria Corsa tubular tyres at the Tour of Oman, it is likely his UAE Team Emirates teammates will utilise the wider tyre clearances during the cobbled spring Classics.
The lugs around the seat cluster have been integrated into the seat tube for the new C64, resulting in a unique seat tube for each size variant of the model. Colnago's C60 ran the lugs separately from the seat tube, but Colnago claims the updated design reduces weight and improves stiffness.
The C64 was also launched with a proprietary stem, a trend which has become more popular in the high-end race bike category, however Costa opts to run a Deda Superleggero stem and pairs it with Deda Superzero aero alloy handlebars.
Another update to the new model is a D-profile seat post, which is the same component used in the aerodynamic Concept model frameset from Colnago.
UAE Team Emirates pair their Colnago frames with Campagnolo's Super Record EPS groupset and Bora Ultra wheels. The crankset comes courtesy of Power2Max with their Type S Campagnolo power meter system, which Costa pairs with 53/39 chainrings.
Costa opts for a Prologo Scratch 2 CPC Nack saddle in the team colours of UAE Team Emirates.
