Colnago Sigma Sports Exclusive C64 Dura-Ace Di2 Disc Road Bike

This Sigma Sports Exclusive Colnago C64 Dura-Ace Di2 Disc Road Bike is a stunning build that incorporates a range of premium performance components. The frameset itself, the most recent in the Italian bike manufacturer's 'C' range, is completely hand made and hand-painted in Italy, constructed from the finest carbon fibres with a gram-shaving unidirectional carbon finish.

Stiffer, stronger and more compliant than its C60 predecessor, the C64 features a re-designed fork, a thinner-walled head tube and a narrow lower downtube, the latter creating a shape with improved proportions, which reduce drag thanks to a recessed area to hide your bottle out of the wind. The seat tube and seat tube lug are now formed from a single piece, and the bike borrows the seatpost design of the V2-R for improved bump-smoothing compliance and all-day comfort, with the integrated clamp shaving weight and keeping the aesthetics clean. This is a bike that equally delivers whether on race day or for a long day in the mountains.

Shimano Dura-Ace Di2 electronic components make up the drivetrain. Smooth, precise shifting occurs from a light touch of the lever, while the hydraulic disc brakes bring the stopping power required for confidence at speed, no matter the conditions. The bike rolls on tubeless-ready Mavic Cosmic Pro Carbon disc wheels and Yksion Pro tyres in a 25mm width, a performance pairing that balances aerodynamics and stability thanks to the 45mm aero-optimised rim, and there's room for 28mm tyres if you wish to go wider still for further improved comfort, less rolling resistance and a reduced risk of punctures.
