About rear brake hose. It's a good idea to put foam around the brake hose before routing it through down tube.
Then we enjoy the silence when riding 😊

That should be mentioned in this tutorial 😉

Good timing. I'm building a bike on Ultegra Di2 12spd. 😅

A thing to mention:
The olive comes pre-placed inside the shifters. So if you're just swapping shifters, MAKE SURE TO TAKE IT OUT

Thank you for the Vid. I just ordered a Elves Eglath frame, and will be doing my first di2 and disc brake build. I ordered the Ultegra, but I am sure the process will be the same. Will keep this for reference.🚲

About the brakes, I prefer the British setup because it's the same as motorbikes, which I am used to !

Excellent video and tips! Just what a Di2 newbie needs. Thanks,

The 105 calipers really aren't much heavier than ultegra and look nice in the black paint.

Please consider the extra cost of junction and cabling so you can connect the levers and update their firmware, which is most certainly needed. This is better done off the bike before installing the groupset. I have done it before installing my dura ace and now i should it again as a new firmware is available.

Those Brit’s has to be different with their brakes don’t they😂😂😂

[jamescourier]

Great! Your vids are the best- very informative tutorial here. How does the Vanyar ride compared to your Falath Evo? 😃

What large torque wrench do you use? That seems to be a fair price for a torque wrench that exceeds 5-10 nm

If I’m upgrading from 105 12 speed mechanical to ultegra Di2, do I need to change the hydraulic brakes or just the shifters?

[rasmuswh]

Hmm I just received a complete R7170 groupset, and there doesn't seem to be pre-installed brake olive in the shifters. Removed the screw completely to be sure.

No break bleeding required? You mention that there is mineral oil in the hoses, but doesn’t cutting them insert air into the system?

[Countrystock]

How do you update the firmware?? Do you need the Bluetooth adapter??

[bobwilliamson]

Does the bike come with " lane keep assist" ?.

[brittle]

You don't need to bleed the brakes?

[markusseppala]

It's pretty logical the left right shifters weigh the same they both do exactly the same thing.

[MGRSD]

Would've been easier if you went with SRAM...

Drive on the wrong side of the road, put your brakes on the wrong side of your bars.. why do you have to do everything backwards? 🤪
