Bianchi Oltre 105 Di2 Disc Road Bike
With the same slippery profile as bikes higher up the range, the frame has cutouts in the seat tube and down tube to better smooth the airflow over the wheels and dropped seatstays to reduce drag. The frame has also been designed to channel air over the bike in specific paths, helping to reduce the effect of wind resistance on both the bike and the rider.
Stem, seatpost and handlebar have all received the aero treatment too, and integrate perfectly into the shape of the frame, giving the bike a very sleek and purposeful look. The 50mm deep Velomann Carbon wheels also help with the bike’s fast-looking aesthetics as well as providing a real performance advantage when up to speed.
Electronic shifting gives a genuine performance boost, with Shimano’s 12-speed 105 Di2 drivetrain ensuring effortlessly accurate shifts every single time, even under full pedal pressure. Connecting the system to a GPS unit or smartphone provides battery information, ride data and even some customisable options. Speed requires control, and the 105 hydraulic disc brakes provide plenty of confidence-inspiring power when descending or cornering, so as smooth momentum as possible can be carried onto the next straight.
