Colnago has outfitted this CX Zero Disc bike with Shimano Ultegra Di2 electronic shifting. Electronic on a bike designed for bad roads might not be your first choice, but for two things. First, the shifting won’t get mucked up by mud and grit. Second, and possibly more importantly, the electronic internals are significantly smaller and thus leave room for a hydraulic reservoir in the brake lever body: so, yes, this bike has hydraulic disc brakes.

Hydraulic discs offer many advantages over cable-actuated. The pads are self-adjusting, so there’s very little maintenance on your part. And better yet, both pads move at the same time, improving modulation over cable-actuated disc calipers as well as increasing pad life.

These brakes top Shimano rotors, which are designed with cooling fins and multiple alloys to better dissipate heat. This is how they get away with using 140mm rotors on road bikes.

The rotors are affixed to DT Swiss wheels. DT Swiss makes everything, the hubs, the spokes, the rims. The company has long built durable hubs with a great ratchet engagement system, and their experience building disc-brake compatible mountain bike wheels is such that the crossover for them was easy.  The wheels come with 25mm Continental Grand Sport Race tires, for an appropriately efficient, comfortable ride.

The Shimano Ultegra Di2 group is an eleven-speed component system that offers the performance of Dura-Ace without the price. 50/34 rings paired with an 11-25 cassette. The shifting is always perfect, and with the incredibly stiff four-arm crank design, you’ll have no reason to worry about energy being lost to chain ring flex.

The CX Zero Disc, as described elsewhere, is the first time Colnago designed a frameset with disc brakes in mind. The lay-up and shapes reflect the forces that not only what heavy braking does by the hub, but how human power from above and the road from below affect the ride. As the intermediary to the road, the bike was designed to be ridden fast, with a confident, stable, comfortable mien.

Everything about it came to mind as a response to cobblestone classics. And what makes it kind to riders there makes it plush to riders on smoother roads. For all that comfort, it still handles like a racing bike. The taller head tube and shorter top tube put you in a position that racers have used for generations. The massive bottom bracket area ensures that your power is driven to the rear wheel. The tapered 1 1/8″ to 1 1/4″ steerer tube keeps the bike tracking the line you choose no matter how hard torsional forces are.

The Colnago CX Zero Disc Ultegra Di2 bike takes your hardest rides and makes them easy.
