Shimano Ultegra R8070 Hydraulic disc brake Di2 STI levers provide incredible comfort, modulation and performance, making them a perfect choice for any high-performance road bike. Designed to work as part of a Di2-equipped drivetrain, these STI levers communicate with your front and rear derailleurs to offer a clean, precise shift every time. Operated by two shifting buttons which are in the same place as mechanical levers, these buttons are easy to use, even in thick winter gloves. Additionally, without any cables to rust or corrode, Di2 offers an incredible shifting performance that lasts.

Powered by a battery that sits in the seat post, the Di2 shifters are incredibly water-resistant and durable – ideal if you regularly ride in poor weather. They’re also Syncro shift compatible too, so you can customise the shifting of your drivetrain. Equipped with hydraulic brakes, the Shimano Ultegra R8070 shifters offer exceptional stopping power, particularly in poor conditions. Significantly, riders can adjust the reach of the lever to suit a variety of hand sizes and bike fits.
