|Features||JUST A FLICK OF YOUR FINGER
Of course, to make a difference, you have to be in top shape yourself. However, Shimano Ultegra Di2 components give you the edge over your competition. 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.
SMOOTH AND EASY SHIFTING UNDER HEAVY LOAD
THE BENEFITS OF ULTEGRA Di2
Anyone opting for Shimano Ultegra Di2 doesn't have to worry about the technology. You'll be able to exert your fullest effort in even the most extreme of conditions. Ultegra Di2 has been built upon the experience of countless professional cyclists.
If it works for them, then it will work for you.
Levers have been ergonomically designed for maximum control and total comfort. Derailleurs shift as quickly as you fingers can move. One click and the right gear is engaged instantaneously. Di2 is faster than regular shifting systems. In a sprint, a fraction of a second's difference in shifting speed can be the difference between winning and losing.
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.
ULTEGRA Di2 ST 6770 DUAL CONTROL LEVER
++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)
SMOOTH AND EASY SHIFTING EVEN UNDER HEAVY LOAD
The front derailleur's operation is pioneering. Smooth shifting is guaranteed thanks to a microchip communication link with the gear levers. What's more, shifting the rear derailleur automatically trims the front derailleur. This ensures that the chain never rubs. Its rigid construction guarantees swift, silent, smooth shifting even under the most demanding of conditions.
ULTEGRA Di2 FD 6770 FRONT DERAILLEUR
++fast, accurate, smooth shifting
++programmed, automatic trim – silent shifting
++weight: 162 g
EASY SHIFTING AT A TOUCH ACCURATE AND EFFORTLESS
The rear derailleur is pre-programmed allowing you to shift gear quickly and accurately in all conditions. The derailleur is immune to rough circumstances and protected from impact damage by its reinforced inner cage. It has a maximum sprocket of 28T for wide-range gearing.

++never drops out of alignment
++crash saver function
++inner cage impact protection – cage moves automatically inwards on impact
++max. rear sprocket: 28T for wide-range gearing
++weight: 270 g
HIGH-PERFORMANCE LITHIUM ION BATTERY WITH EXCELLENT RELIABILITY
The battery forms the Di2's heart. Its lithium ion technology guarantees a range of at least 2,000 km [1,250 miles] after which it can be fully recharged in just ninety minutes.
The battery's status can be read from an indicator next to the handlebars so that you'll never be confronted with any unpleasant surprises. Derailleurs can also be reset or trimmed from this control unit.
ULTEGRA Di2 SM BTR1 BATTERY
++high-performance lithium ion battery (7.4 V)
++easy to assemble/dismantle
++charging time: 90 minutes
++weight: 71 g
ULTEGRA FC 6700 CRANKSET
Shimano HOLLOWTECH II crankset with integrated bottom bracket for lightweight design and excellent rigidity. This allows the cyclist's muscle strength to be converted into forward motion as effectively as possible. The cut-out chainrings provide added weight savings and rigidity.
Tooth design and shift ramps on the inside of the large chainring enable even easier and smoother shifting from one chainring to the next. A compact version is also available especially for mountainous terrain.
++chainring sets: 52T–39T or 53T–39T
++compact chainring set: 50T–34T
++crank arm length: 160 / 165 / 170 / 172.5 / 175 mm
++weight: 790 g (53–39T) / 788 g (50–34T)
++both 170 mm in length inc. bottom bracket
ULTEGRA BR 6700 BRAKE CALIPERS
Exceptionally powerful, adjustable and controlled application. Braking is now even more powerful and faster thanks to a modified cable inlet. In conjunction with STI levers, these brakes provide the ultimate in stopping power. Improved compound brake shoes have improved braking in wet conditions by 100%. A light touch of the brakes going into a bend or a full-on emergency stop… either is possible thanks to the brakes' controlled application.
++interchangeable brake shoes
++adjustable braking force
++weight: 317 g
ULTEGRA CS 6700 CASSETTE SPROCKETS
Rapid gear shifting is achievable using components that have been designed to be used with one another. The cassette is an important element in the drivetrain. This is why the sprocket design has been optimized to allow you to get the most out of the Di2 system.
++weight: 209 g (11-23)
ULTEGRA CN 6701 CHAIN
The forces exerted on a chain are incredibly large, yet its role is to provide smooth power transfer. The chain has a unidirectional design to reduce chain suck and improve shifting performance. This chain features perforated plates that help to reduce the weight to 267 grams.
++weight: 272 g (116 links)
ULTEGRA PD 6700 PEDALS
To complete the system, opt for Ultegra SPD-SL pedals.
These are available with extra-wide platforms for better power transfer. The bearings used are maintenance-free and their wear-resistant top surface makes them exceptionally durable. Their aluminium spindles make them incredibly lightweight too.
Two versions are available - aluminium and carbon.
The aluminium version weighs 314 g a pair while the Ultegra pedals with a carbon composite body reduce the weight to 265 g a pair.
++adjustable spring resistance
++weight: 314 g / 265 g
