Reviews over the

Shimano Ultegra R8050 Di2

Very happy, so difficult to find 11-speed equipment. Allows me to switch to 11/34 instead of the 11/30 of the Dura Ace derailleur.

Very good derailleur. Now you can fit mountain cassettes. Ceramic rollers can also be fitted!

I've been using Di2 components since 2015 and have been completely satisfied with them ever since.

After having cycled with Di2 for years, you don't want anything else. It shifts accurately, quickly and easily, e.g. by trimming the front derailleur so your chain never touches the cage. One adjustment and you're set for years to come. Unfortunately, my old rear derailleur had broken (6800) series, so I quickly went looking for a new one. This R8050 was plug & play. Same connection, one adjustment and it rides like a charm again. The long cage is a nice bonus, I ride with 52/34 front and 11/32 rear, so it works fine!

Is a fantastic shifting system My previous one had broken down, motor, probably due to a crash
