Shimano 105 Di2 brings pro-level performance within reach. Drawing on technology from Dura-Ace and Ultegra, it delivers the same lightning-fast, accurate shifting and smooth, intuitive control and now more accessible than ever. With refined ergonomics, 105-optimised gearing, and the all-weather confidence of hydraulic disc brakes, 105 Di2 redefines what performance feels like on every ride.

Engineered for pure speed, the ULTRA-AERO bars are purpose-built for our fastest-ever aero bike. Their patented, next-generation design introduces a revolutionary wake-generating concept that reshapes airflow, creating a controlled pocket for the rider’s legs to sit within and reducing drag where it matters most. The aggressive, wing-shaped tops slice the air with scalpel-like precision, while the ergonomic drops and flat-top section deliver comfort and control on long rides or steep climbs. A textured finish removes the need for bar tape, keeping things clean, fast, and uncompromisingly aerodynamic.
