Why We Like The Ultegra Di2 ST-R8050 11-Speed Shifters

They say the third time's a charm and Shimano continues to bring Di2 to the masses with the much-refined gen 3 Ultegra Di2 ST-R8050 11-Speed Shifters. Exceptional electronic shifting and powerful braking are at your fingertips, and the value and performance of this group are simply remarkable. Borrowing heavily from the top-tier Dura-Ace levers, the R8050's are redesigned with improved ergonomics in mind. Because much less space is needed to house electronic buttons versus mechanical bits, the hoods are more compact, lighter, and the lower profile just feels great. Shimano even went so far as to create a new rubber compound and tread for the hoods that are designed to reduce vibration and improve grip. Gloves or no gloves, the tactile grip is amazing and our hands refused to slip even when climbing out of the saddle with sweaty hands on a hot ride. Befitting riders with bigger and smaller hands alike, a lever reach adjustment places the brake levers just where you need them for maximum comfort and control.

The shift buttons are easy to reach both from the hoods and in the drops and, again trickled down from Dura-Ace, have a more positive click and are more distinguishable between upshift and downshift than previous versions. What we love most about Di2 is that shifting feels akin to clicking a mouse, only requiring 2mm of movement. This requires much less focus and effort, especially for front shifting, allowing us to concentrate on riding without thinking too much about our equipment. Remote sprinter and climbing satellite shifters are available separately, plugging into these shifters to allow further customization.

I have a 2015 Cannondale SuperSix EVO that came with Shimano Ultegra Di2 11 speed group set and components. I am looking to replace the shifter/brake levers as they are a bit battered from a fall and the rubber hoods are also torn. Is the Di2 ST-R8050 Shifter the correct replacement? The hood design seems slightly different. Thanks in advance for your advice. GY

Hi Glen, you have the ST-6870 shifters which swap well with the ST-R8050s. Feel free to reach out if you have any other questions.

Welcome to the future

DI2 is incredible. I have ridden every kind of component in mechanical form and now switching to electronic shifting I am blown away. The shifting is crisp, clean, and reliable. My favorite part is once set up, maintenance is next to none.

Are these levers compatible with Shimano RS785 Hydraulic Disc Brakes?

No, these are for rim brakes only.

No, these are for cable actuated brakes only.
