Colnago Sigma Sports Exclusive C64 Dura-Ace Di2 Disc Road Bike
The most recent release in Colnago's 'C' range, the C64 Disc Road Bike has had a number of updates since its C60 predecessor, making it lighter, stiffer and more compliant. It's presented here as a Sigma Sports exclusive, built up with a top spec, including Shimano's Dura-Ace Di2 components. Among the changes are a unidirectional carbon finish to shave off some extra grams, a thinner headtube with improved vibration damping and a one-piece seat tube and seat tube lug. The fork has been redesigned with an external rib shape to improve comfort and handling and there's now clearance for 28mm tyres, increasing versatility for the rider.
Shimano's range-topping Dura-Ace Di2 components are the perfect addition to this build, with internally routed cables keeping the aesthetics sleek. Shifting is precise, smooth and instant, at just a light touch of the lever, and the mid-compact gearing brings plenty of options on hilly routes as well as when sprinting on the flats. Hydraulic disc brakes will inspire the confidence to ride fast no matter the conditions, with excellent stopping power even on wet roads. The bike rolls on Knight Composites 35 Carbon Clincher Disc wheels with DT Swiss internals, for instant acceleration and low rolling resistance. They've been fitted with Continental's latest performance tyres, GP5000s, to bring additional comfort, puncture resistance and a supreme ride feel.
