Shimano Ultegra Disc R8020 Groupset

The Shimano Ultegra Disc R8020 disc brake groupset excels in braking and shifting performance. Thanks to newly implemented techniques originating from the Shimano R9100 Dura Ace group. The Shimano R8020 groupset offers great value for money to finish your road bike with disc brakes with top-notch material.

The Shadow rear derailleur that is better protected from external damage by the alignment under the cassette, more compact design and cable adjustment of the front derailleur, well-dosed braking power in the shifters, powerful braking calipers and the crankset with improved power efficiency and transmission.

Technology

Shifters
The Shimano Ultegra R8020 shifter + brake caliper offers an unprecedented well-dosable braking force in descents or quick passages. The shape of the shifters is pretty similar to the R8050, R8070 and R8000 shifters. They have a short lever throw, a compact design and an excellent braking performance in all conditions.


The Shimano Ultegra R8000 may well be the most striking part of the R8000 groupset. The robust, asymmetric crank arm is derived from the Dura Ace R9100 crankset and provides a more efficient crank transmission compared to its predecessor. The crank also contains the HollowGlide technology for the best ratio between weight and maximum rigidity. There is a wide range of different chainring combinations that are also easily interchangeable with a double 53-39T, mid-compact 52-36T, compact 50-34T and the 46-36T for cyclocross use.

Front derailleur
The Shimano Ultegra R8000 front derailleur is the result of the development of the R8000 groupset. Besides, the design features no in-line cable tensioner and offers instead an adjustment by means of an Allen key for an easy and accurate cable tension adjustment.

Rear derailleur
The Shimano Ultegra R8000 rear derailleur is a part of the successor of the popular 6800 groupset. The R8000 is very similar to the R9100 rear derailleur, as this R8000 rear derailleur copies the entire Dura Ace Shadow design, including complete protection under the cassette. This is a huge advantage for people who ride in groups in which a rear derailleur breaks sometimes. The rear derailleur is supplied in a short cage (SS) design for 11-25T up to 11-30T and a long cage (GS) design for 11-28T up to 11-34T cassettes.
