The Bianchi Specialissima Pro MW Ultegra Di2 12SP is a race-oriented road bike that pairs an ultralight Specialissima Pro frame with Shimano’s 12-speed Ultegra Di2 electronic drivetrain and hydraulic disc brakes. Its combination of CounterVail vibration damping, precise handling, and high-end components delivers efficient power transfer, smooth shifting, and reliable stopping on any road.
Specialissima Pro full-carbon CounterVail frame optimized for stiffness-to-weight and vibration damping
1 1/2"–1 1/2" tapered head tube integrated with Acros IS52 ICR headset for precise steering and a clean aerodynamic profile
PressFit BB86.5 × 41 mm bottom bracket shell paired with Shimano Ultegra FC-R8100 52×36T crankset (compatible with 4iiii Precision 3+ power meter) for direct power transfer
Shimano Ultegra Di2 ST-R8170 hydraulic disc brake levers with BR-R8170 calipers and 160 mm RT-CL800 IceTech rotors front and rear for consistent all-weather stopping power
