Bianchi Infinito 105 Di2 Disc Road Bike 2023
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.
