Questions & Answers

There is no mention on the listing of whether this is a 10 speed or 11 speed unit. ?

Straight out of the box, this bike is 11 speed.

What are the compatibility issues between this derailer and the Ultegra Di2 R8070?

It seems so to me.

How does it compare to the 6770 shifter? An example of a 2012 Madone 5 can be found here. It had a 10SP di2 and a 9 that came with it. Four years after the FD & RD were replaced, 6870 parts were installed. There is a story about a dead body. ?

We won't be able to work together. In the 11spd 8050 Di2 Rear Der, there are different pulleys and the Parallelogram movement is different.

Selected User Reviews For SHIMANO Ultegra Di2 R8050 Short-Cage Rear Derailleur

A great derailleur for Di2

5/5

For Di2, this is an excellent derailleur. From a short cage Ultegra derailleur, which only allowed cassettes of 28t, I moved to a long cage derailleur, which has larger cassette sizes. In this way, I was able to upgrade to a 34t cassette specifically for Shimano does not make a 36t road cassette. I believe you can go up to 36t by using smaller cogs. I like how smoothly it shifts and how well it works. You will always be able to hit the right button every time. The action is lightweight and crisp. This means that you will no longer have to trim or press the lever further to adjust your gear. To update the firmware and to control the shifting, you can use the Shimano app. There is a great deal of flexibility in it.

For cassettes larger than 16 x 2, this upgrade is perfect

5/5

To get an 11- I wanted to switch from an 8- It took a few days to load the 32 cassette, and the smaller stock cage was not smooth at all. Changing to the larger caged DI2 was easy, and my drivetrain has returned to its normal 11-speed configuration With an extra hill climbing ability, the 28 performs as well as 32.
