Same goes for the company: ceetec company
Just for the rear conversion, K-Edge charges $335 if you supply your own derailleur. That's too steep for my blood!

The plug has to be cut off the end of the A junction wiring harness that goes into the lever and cut off of the satellite shifter then you soldier the wires together. The satellite shifters still fetch $150 so I am thinking about doing Cateye buttons for both front and rear derailleurs. Maybe place one on each side of the brake lever clamp. The E-tube system has its advantages with easy of assembly but the original 7970 is less complex (not a Canbus system) so it can be hacked easier. I have yet to see an E-tube on a MTB, they are all DA 7970 with some type of custom hack wiring for the shifters.
Can share more details about the satellite switch mod for the 9070 mtb thingy? Can't I just plug the satellite switch directly into junction A? Will it work this way?
To user Mpower: the satellite switch needs to be adjusted with the e-tube program, otherwise the switch thinks its a rear switch only. Dont know currently how many gears does it read 10 or 11 but sure let you know when the build progresses!
34 tooth Hope ring up front,
Shimano XT 11-36 tooth 10 speed cassette with the 15 & 17 rings removed and replaced with a Durace 16 tooth,
and a One Up components 42 tooth cassette ring.
so its now an 11-42 10 speed cassette,
Ultegra Di2 rear mech with modified B spring tension, modified Ultegra GS rear mid cage, and a custom machined front mech cage, i will post some pics once its back from the anodisers, i may have a few spares if there is any interest.
internal wiring run Ultegra set up switch box and a modified Alfine Di2 switch lever, i only modded the clamp to fit too a Formula R1 matchmaker.
the whole lot works fine on the stand and test rides so just getting a better looking cage plate made up.
As long as you use the PC interface box to set everything up through E tube ( which finally works with Windows it all works fine.
to me this seems an easier mod for the shifter rather than the satellite switches, i haven't cracked the Alfine swtich unit open but reckon it could be switched to left or right mounting without too much effort, and i guess it could be prgrammed to be front or back shifter from the Etube software.

Am I of the correct understanding that you need to hack an existing shifter to gain the necessary protocols? Or the brains of the system is the junction boxes? I ride a Handcycle and do not need the conventional brake shifter set up. Any thoughts? Thanks.
Where are your shifters located? You could probably use the 2 button climbing shifter that zip ties on to the handle bar. No hacking necessary. The "brain" is in the derailleur.
