Ultegra 8070 Di2 Question
Moderator: robbosmans
I'm looking to upgrade my 2015 Felt F3X from mechanical Ultegra 6800 to hydraulic Di2 8070. I plan on using the bar end junction box and a Y cable to the shifters. I have a couple of questions about implementing this. First of all, are the 8070 shifters compatible with sprint shifters? Are they just plug and play or do I need some kind of other junction box or something to hook them up? Secondly, with the new short cage 8050 derailleur being capable of running an 11-30 cassette, will it run an 11-32 without any issues or should I plan on getting a long cage derailleur? (I'm currently running a long cage 6800 derailleur with either an 11-28 or 11-32 depending on the wheelset. The 11-30 sounds perfect for me but I'm trying to save money and stick with what I have for now.)

The R9170 and R8070 hydro levers do not have the dedicated port for the sprint shifter buttons. The R9150 and R8050 rim brake lever do have these ports.
So then how do you hook up sprint shifters?MoreRideTime wrote: ↑Wed Mar 07, 2018 7:42 pmThe R9170 and R8070 hydro levers do not have the dedicated port for the sprint shifter buttons. The R9150 and R8050 rim brake lever do have these ports.

The shifters have three ports each - the top two for E-Tube plugs and the bottom one will only accept the plugs on the sprint shifter.CallumRD1 wrote: ↑Wed Mar 07, 2018 7:52 pmSo then how do you hook up sprint shifters?MoreRideTime wrote: ↑Wed Mar 07, 2018 7:42 pmThe R9170 and R8070 hydro levers do not have the dedicated port for the sprint shifter buttons.

No they do not. This thread was a about connecting sprint shifters to R8070 hydraulic levers, which as already mentioned by ooo is not possible.BdaGhisallo wrote: ↑Wed Mar 07, 2018 9:32 pmThe shifters have three ports each - the top two for E-Tube plugs and the bottom one will only accept the plugs on the sprint shifter.CallumRD1 wrote: ↑Wed Mar 07, 2018 7:52 pmSo then how do you hook up sprint shifters?MoreRideTime wrote: ↑Wed Mar 07, 2018 7:42 pmThe R9170 and R8070 hydro levers do not have the dedicated port for the sprint shifter buttons.

My apologies - I should have read the OP closer. Yes, the hydro shifters do not accept the old sprint shifters.MayhemSWE wrote: ↑Thu Mar 08, 2018 11:29 amNo they do not.

SW-R9150 can be used with ST-R8070/R9170 instead of SW-R610 (comparison on 2nd pic)
It looks like Kittel have them on Venge Vias disc.
They are flat, but shimano flat-to-round adapter is bulky (see top of 3rd pic)
To mount them nicely you may need adapter with 3m (bottom of 3rd pic or diy)

Thanks for the information. Does this mean that the SW-R9150 shifters can plug straight into the 8070 STIs?ooo wrote: ↑Thu Mar 08, 2018 11:55 amSW-R9150 can be used with ST-R8070/R9170 instead of SW-R610 (comparison on 2nd pic)

Hi this is an excellent thread. Without having to pay out for further components can I do the following from these two set ups
Ultegra Di2 6870 has 5 port junction box
Ultegra Di2 8070 has 3 port junction box
I want to swap the junction boxes so I can plug SW-600 into 8070 bike then plug SW-610 into shifters on the 6870 bike.
Any advice welcome

So slightly off toppic... or maybe tangent...
Does this mean that hommade sprint shifters (cut e-tube cable, solder on button) won't work with the hydro levers?
