Shimano Ultegra Di2 Shifters - STI Dual Control ST-6770 2-speed
For the past four years, professional riders have been riding Shimano Dura-Ace components
with Di2 electronic shifting technology over the highest mountains, the worst cobbles and
through the most extreme weather conditions imaginable. As of this year, Shimano Ultegra
will also be fitted out with this groundbreaking technology.
What are its characteristics? Just the same as for Dura-Ace. Changing gears becomes easier,
effortless and faster by simply touching the shift buttons. Control at your fingertips. Additional
benefits include an automatic trimming front derailleur, great accuracy plus easy adjustment
and installation. Di2 continues its great success with Shimano Ultegra. And it makes no difference
if these roads are cobbles, tarmac or mud.
Advanced 3D design and extensive testing
have allowed us to find the perfect balance between shifting speed, ergonomics, strength, weight
and rigidity. With just a flick of the finger, Di2 technology enables faster, precise and multi-precision
shifting plus automatic trimming.
Intuitive shifting with less effort and more precision
Anyone who has experienced Shimano`s mechanical, ergonomic STI levers knows just how much
control they have over all components. With Di2 technology, shifting is even easier and more precise
- just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously
select the correct gear. Shimano riders will be used to them immediately since all the buttons are in the
same place as on regular levers. The distance between the lever and the handlebar is adjustable. This
makes it extremely easy to brake and shift even for riders with smaller hands.
Details:
- lightweight levers for optimal comfort and control
- digital push button shifting - like clicking a mouse
- ergonomically designed hood shape
- lever reach adjustment - fits all hand sizes
- weight: 313 g (pair)
