Description
An endurance bike that's also fast, the Bianchi Infinito 105 Di2 Disc Road Bike is the perfect choice for long road races and gran fondos. Endurance geometry, with a taller, aero headtube to put the rider in a slightly lower stress position, plus longer chainstays, come together with Countervail technology to cancel vibrations and create a far more comfortable ride. Aerodynamics are enhanced by the inclusion of a newly designed carbon seatpost and a bladed fork.
Ultegra Di2 12-speed is Shimano's mid-range electronic offering, featuring trickle-down technology from Dura-Ace. Shifting is incredibly smooth, fast and precise across the wide-ranging 11-34t cassette and there's only a slight compromise to weight. Hydraulic discs create reliable stopping power in all conditions. The cranks, stem, handlebar and seatpost are all frame-size specific in order to optimise fit for every rider.
Fulcrum Racing 400 wheels are a solid choice, robust yet fast rolling and rigid, well suited to long hours in the saddle. They're fitted with Pirelli P7 tyres in a comfortable 28mm width, with room to go wider still; up to 32mm.
