Well i've got a gripshifter and stripped it down and it looks like it should be easy to install some switches and the Di2 electronics module from an Alfine unit i have, just trying to work out the best way of getting the haptics sorted with nice click when you shift. I think thats the bit that will take the time.

Gonna gut the LH shifter to operate my dropper post for a nice balanced looking setup.

I guess it won’t matter that I’ll be using the xtr display rather than the junction box.
Keep in mind that sc-m9051 has built in Bluetooth so you don’t need (or can’t use with it) other wireless units

Here is my R600 implementation. It's not so much "under" the bar as easily reached while my index finger is on the brake lever. Shifter is secured to bar with thin 3M 2 sided tape and 2 black zip ties. It is perfectly secure. Was fine during a 5 1/2 hr race in which my Garmin logged 830 shifts as well as several shorter rides since.

I did the same thing to mine but was never 100% happy with the location or the mushy click of the shifter.
It was always my intent to recreate an etap setup and not the satellite shifters are available, it looks to be a simple option.

Just waiting for mine to be delivered along with a oneup 45t xtr expander.

Thread update time.

The one up 45tooth expander is awesome. A little heavier than expected at 85g for the big ring and 15g for the 18t , but it did replace a 17/19t combo nets out about 420grams for an 11-45 cassette.not the lightest but I don’t want to change to a XD driver so pretty good for a shimano fitting cassette with that range.

The satellite shifters DO work. And they work very very well.
The two satellites are 25g in total so a fair chunk less than an r600 or xtr trigger unit. They feel great with a nice positive click but I’m still playing with their final position on the bar.
Pics to follow one I have them nice and neat and in their final resting place.
