Shimano Ultegra R8070 Di2 Disc Brake 11 Speed Groupset
The Ultegra R8070 Di2 groupset is the latest development in the evolution of the electronic groupset from Shimano. Taking technology from the Dura-Ace Di2 groupset while at the same time refining the previous version of their Ultegra Di2 groupset Shimano have tweaked the ergonomics of their Di2 shifters and included more shifting options to enable you to fine tune your setup to suit you. With improved clearance for wider rims and tyres as well as a new Shadow Technology rear derailleur that gives a lower, more aero profile and increased protection from crash damage the Shimano Ultegra R8070 Di2 Disc groupset marks a significant development in the evolution of Shimano’s Di2 electronic drivetrain.

Richard Great value package. Be sure to check The lengths supplied and ensure you have all the lengths of di2 cable you require for your build, order additional if needed . Also check the the length of Rear caliper bolt that’s needed for your frame chainstay as the ones that were shipped with mine were for a 15mm thick chainstay and I needed one for a 25mm.
Glen Everything was as expected. I even ordered the wrong derailleur size and bottom bracket but the customer service team were great in sorting quickly for me. If you are debating whether to upgrade to Ultegra, don't, as there is a remarkable difference. DI2 is a dream too. You can also DIY if you do plenty of research.
Ade I’ve owned durace di2 and sram 11 and 12 speed and have to say this groupset is all you need . Reliable , smart , easy to fit and maintain.
Mr Liu Incredible performance. Very very close to dura ace but much cheaper
Ray Fantastic groupset at an amazing price, good to able to choose different options. All fitted and working perfectly.
Matthew All excellent as ever with Shimano. A delight to use - light and accurate shifting, great feel and power from the brakes.
Ollie Got an awesome deal on this Ultagra groupset from Merlin. I liked how it included everything including wires, junction boxes, battery and charger as some other suppliers don't. A couple of items which it would be good to see included are wire grommets and internal battery seatpost mount, although the team advised that bubble wrap was a go-to option for the latter. Yet to install but all parts in good condition and no damage. No flashy Shimano boxes which wasn't an issue for me, but it would have been nice to see the instruction manual included. This can however be downloaded here https://si.shimano.com/pdfs/dm/DM-R8050-01-ENG.pdf Overall, very happy with my purchase and service form Merlin.
