Love di2, don’t want anything other anymore! Works!

When I got down to finishing the di2 part of the build i realized if I just run a long wire to the RS910 I have to dangle it if i want to work on the cockpit by taking it off the fork like a mechanical build so I did wind up bridging a coupler right outside the frame with 2 segmented lines to easily remove the cockpit/handlebar on the table. Thanks again ! That damn yspit is one of the stupidest "solutions" to a problem that should not exist.

does that way of doing it allow you to connect sprint shifters?

I used a second Junction B to replace the old Junction A and it was plug and play (All 9150). I drilled a small hole just above where my thumb rests in the drops allowing the 250mm e-tube wire to exit and connect to the right shifter.

Hi Cyclespeed Tours...Just an update on my DI2 sync shifting upgrade. I managed to finally update my old 9070 front and rear derailleurs today. My Sync and semi sync shifting works a treat. OLD with NEW. A long wait but finally done it. The only new parts i've added are the seat post battery and d-fly. One thing to mention is that when using the 3 port junction, to switch modes between normal, sync and semi sync it's worth noting that the default is normal. Pressing the button on junction A twice shifts between the 3 modes which I never knew. 1 flash is normal, 2 is sync shift and 3 is semi sync. Worth noting as I thought it wasn't working until I figured it out myself. By the way, I put my d-fly in the toptube towards the front headset , released the fork to do so. works a treat there, and got a 350mm wire to go from the d-fly to junction A through the di2 hole where the rear brake cable enters the top tube. I too have an sworks tarmac 2016 stealth 52.

Great video. Thanks. Buying the parts currently to do to my Tarmac with the Aerofly bars. I am assuming based on how the bared junction box mounts; you are not able to over wrap bar tape and hold in place with the plug.

Very interesting video, thanks!! just two questions please: 1. does this cabling work also for the 9150 DA? 2. the 70 cm cable connecting the 2 shifter ... I was expecting it connecting the left shifter with the RS910 junctionbox instead of the right shifter ... am I wrong??

Great vid thanks. Do you recon this could be used with Ultra DI2

Un grand merci j'ai essayé ça fonctionne très bien

Thanks for this great vid, I've just bought a rs910 and connected everything the way you said. The shifters are working but the led indicators on the junction box aren't. Any thoughts? When I connect the old junction the leds are working.

Everyone, just a quick note, the method in the video will not work with the BR-RS 785 shifters (the older hydraulic di2 ones with the silver face). This is because this type does not have the triple wire connection at the shifter, they only have one wire connection. For these shifters you will have to use the 'Y' wire, and if you want satellite shifters it might be easier for you to just use the traditional 3 or 5 port junction box.

Is this configuration possible when aero bar shifting units SWR671P exist? Thanks.

Where would you put the Bluetooth transmitter then? I presume you'd have it somewhere along the really long cable near the head tube.

With a house that big, you should be able to afford a mic.

Thanks much ! The di2 guy at my bike shop (who helped me with allot of stuff) was totally wrong on having to have the y split. I can as you said just use the 1200 di2 cable. Only problem with this method is if you are going to use climbing shifters on the right (which i am.) Sidebar: Why have e shifting if you can't shift from the tops ?) All 3 ports in the right shifter are used and I had to use a coupler on the r climbing shifter to hook to the left shifter. The other way I could do it is put the RS910 on the left side*. Then it will work (not for me though I have a mirror.) Regardless thanks this helped me think outside the box.

I have copied this set-up but cannot get it to work? My system uses 6870 shifters, 6870 Front Derailleur and 8050 GS rear Mech. Battery is the SM-BTR2-1. When I tried the E-Tube program it asks me if I want to use the Sprint button on 6870-R (which I dont have). Then doesn't recognise a MASTER unit? Can anyone help as it literally took hours to run the cables :(

Can ergonova team ?

Sort your volume/background noise out!!

I would not cut holes in my bars at those locations
