Shimano Ultegra Di2 technology is now also available in the Shimano Ultegra version, offering the same benefits as Dura-Ace Di2 technology but at a significantly lower price. The advantages of Di2, Digital Integrated Intelligence, are obvious and become clear to anyone who tries it just once: shifting becomes noticeably easier, smoother and faster, and allows for optimal control literally at the touch of a button. The electronic Ultegra Di2 Dual Control shift-brake lever unit ensures smooth operation and a unique shifting experience. The operation of the shift lever follows the logic of Shimano’s mechanical system. Therefore, no adjustment is necessary. However, the operating forces are extremely low.

The Ultegra DI2 brake lever is more accessible from above thanks to a closer pivot point. This allows for better control of the braking process. The lever reach is adjustable. The reach adjustment allows the shift-brake lever position to be adapted to your personal riding style. The programme-controlled shifting movement ensures faster and smoother gear changes. The ergonomic grip design ensures greater comfort even on long rides.

The Ultegra DI2 shift-brake levers are supplied with brake cables and cable housings. The EW-SD50 cable, an SM-EW67 cable set, the SM-BTR1 battery and the SM-BMR1 battery mount are also required for operation. Shimano Ultegra Di2 components are not compatible with Dura-Ace Di2 components.
