Shimano Ultegra R8050 Di2 User Manual

Posted on

When Shimano introduced the Dura-Ace R9150 series in 2016 they also released Synchro Shift. Then, a few months later, they made Synchronized Shifting available for Ultegra 6800 and Dura-Ace 9000 users as well. All you need is up-to-date firmware and the current generation battery, the BT-DN110.

The DURA-ACE and Ultegra Di2 shifters in combination with SHIMANO STEPS drive units are compatible with Ultegra (R8050) and XT (M8050) derailleurs. Mechanical shifting If you choose to use SHIMANO STEPS mechanical shifting which lacks the Di2 shift button, it is still possible to ride with drop handlebars. In the image above I have selected the SM-EW90 Junction box, R9150-series Dura-Ace shifters and two 11-speed derailleurs; the RD-6870 Ultegra rear derailleur and the Ultegra FD-R8050 front derailleur. Note that I could also have selected the Dura-Ace FD-R9150 front derailleur if I wanted to. Shimano Ultegra FD-R8050 Pdf User Manuals.

Synchronized Shifting requirements

Synchronized shift is available to users running current or previous generation Ultegra or DURA-ACE Di2 and a current generation battery. This means you need one of the following series Di2 to run synchro-shift:

  • Ultegra 6870
  • Ultegra R8050
  • DURA-ACE R9000
  • DURA-ACE R915
  • XT M8050
  • XTR M9050
  • GRX

You will also need the BT-DN110 battery or BM-DN100 external battery mount.

On mountain bikes the same battery requirements apply, but you’ll also need one of SC-M9050, SC-M9051 or SC-MT800 in order to use synchronized shift. You can use mountain synchronized shift on bikes equipped with either XTR M9050 or XT M8050.

What is Synchro Shift?

According to Shimano; “Synchronized Shift is a function that automatically shifts the front derailleur when the rear derailleur is shifted, allowing the derailleurs to work together efficiently.” This means that you would never manually have to shift the front derailleur anymore. The system will do it for you when it thinks the time is right.

Shift modes

These are the shift modes you can set up:

  • Full Synchro Shift: your front derailleur will shift by itself, when it has to
  • Semi Synchro Shift: when you shift the front derailleur, the rear derailleur will also shift in order to compensate
  • No Synchro Shift / turned off: No automatic shifts will happen. Full manual mode.

When shifting from 11T towards 28T the system will automatically shift from the big ring to the small ring between 25T and 21T

How to set up Synchro Shift

First you’ll need to download the e-Tube Project software. Connect your bike to your computer using either the SM-BCR2 (charger) or the SM-PCE02 (linkage device/diagnostic tool) and start the [https://e-tubeproject.shimano.com](e-Tube software). You can now customise the shifting settings using these steps:

  • Select your bicycle type
  • Do the connection check
  • Click ‘Customize’
  • Click ‘Shift mode settings

On this screen you can select the number of teeth on your front chain ring, select the range on your cassette, set gear position control, shift interval and the shift modes.

When riding your bike you can use three different shift modes. Shift mode 1, shift mode 2 and full manual. These shift mode 1 and shift mode 2 are set up as ‘semi-synchro’ and (full) synchro by default. However, you can set them up however you like. You could for example set both shift modes to full synchro, but have the automatic shift points differ for each mode. I'll talk you through customising the different shift modes in another post.

Change shifting modes on the bike

So you’ve got two custom and one full manual shift modes available – how do you use them? That’s easy! Just double press the button on either your Frame/Bar-end junction box or the below-the-stem junction box and you’ll change modes. In the video below reader Paul Teeter demonstrates how to cycle through the different shift modes.

This is what each light means:

  • Solid red/green lights: manual shift mode
  • Twice blinking red/green lights: shift mode 1 (default: semi-synchronized shift)
  • Three-times blinking red/green lights: shift mode 2 (default: synchronized shift)

GFQuick delivery. Everything you need to upgrade your bike. Looks and works great. Only wish I done it sooner
Simon PMy first venture into electronic shifting and very impressed. Easy to fit and adjust and when out on the road the shifting is faultless. Highly recommended upgrade.
HenryAwesome set and includes basically everything to set up the Di2 system (including the Di2 tool). You just need the specific grommets for your bike frame. Shifts flawlessly and looks awesome doing it. Internal cabling can get a bit tricky, but enough patience with the included brake wire and tape will work.
MalcolmBrilliant bit of kit. Would never go back to manual gear change. So easy quick and look good

Mr SinghCrisp with great battery life so far. Intrgrates perfectly with garmin 530 and buttons on top of the levers provide 6 inputs to navigate the garmin.
Mr BisgaardExcellent, easy installation and it works without flaws. A definite update from 6870, and I absolutely loved it too.
Mr MaraisBest decission I ever made
jaime javierTodavía no lo he probado, pero es un precio competitivo.
Mr HedleySuper pleased. Quick shifting and nice and accurate.
Scott HBrilliant upgrade from Ultegra 6800, and the kit came with everything required for a basic install. The black feels more premium that the dark grey of the 6800 setup I had. New levers are great.
Mr NeethlingThis product ordered is exactly what I wanted and does exactly what it was intended to do. I've always been a fan an enthusiast of Shimano products and cannot ever fault it on any of it's promises. I am really enjoying this product due to its precision, smooth gear changing and beauty. I trust it will deliver a good service, I'm confident of it's reliability and durability.
Mr maharajThe shifting is seamless, with the new Ultegra brakes a massive improvement.
JeffThe new 8050 Ultegra Di2 is phenomenal. The shifting is so crisp and quick. Without looking, you`d think you were riding Dura Ace. The shifting is exactly the same but at a fraction of the price. If you want an electronic upgrade, you will not go wrong with the 8050 groupset.
