Here are photos of my 2015 Trek 7.5 Speed Concept after upgrading to SRAM eTap shifting.
I'm really liking it so far. I have BlipGrips at the end of the extension bars and blips on the inside of the lower horns just under the tape. I changed the brake levers to be Bontrager XXX with the adjustable tension. The blip box is mounted right above the stem with industrial velcro. It was great to pull the shifting cables out of the frame - and leave them out.
