Those excess wires should be in the basebar

When I built my last SC for my s/o, I positioned the Blip Box on the underside of the mono extension.

There were two reasons why I did this:

1. The stem was a Med-Near stem and it was too short for the bulk of the Blip Box and it's wiring
2. Under the mono extension allowed it to be easily removed and also made it for a clean wiring job.
   

If you did the same, you would bring the wires up from the base bar through the stem and they'd run on the inside channels of the mono extension. Personally, I think this is the cleanest way to mount the Blip Box for the SRAM eTap unit.

Appreciate your mount info... can you snap a pic and add to the thread? I think I get what you're saying but a pic would be awesome!

I have the Bontrager carbon bottle cage (BTA) and I have my blip box mounted to the back side of the cage. Blip wires run through the base bar and through the stem under the mono extension then to the box. Very clean.

I have mine mounted on the stem cover with velcro. I have plenty of room there because I use a low far stem. I haven't wired the blips for basebar shifting so I only have two wires coming into it from the extension clicks. I use the mono plug-in with Aerocoach Angles 45deg extensions. I have no extra wire visible, all the extra wire is tucked in the extensions. The wires are routed through the mono spacer and come out from the front of the stem cover where I cut out the Di2 notch that's built into the cover. The blip box sits on the stem cover with wire ports facing the front. I added a black zip tie to keep it in place but the velcro does a pretty good job on it's own.

I really didn't need extra blips on the basebar... I mostly ride flat courses and if I did anything hilly I still wouldn't mind to much shifting on the extensions... Used to it from when I had mechanical. This way I have a really simple setup with no extra wires hanging all over the place. I can attach some pics if you'd like.

What's your CdA?

This is why I’ve chosen DI2 over ETap on my SC:

To tell you the truth next time I'll be getting Di2... The front ring shifting with eTap is complete shit. Luckily I don't really use it down here in Florida.

What's your CdA?

I'm liking the hand position. What extensions are those?

I think that's what I'd planned on doing in my rewire... except I'm using wires on the base bar as well so I'll have four wires coming through the cut out... and sure pics are always a great addition.

Thanks!

Think I got all the pinch zones eliminated with the wires all in the base bar/extensions/forward of the steering pivot area... and I put Clics on my aero bars.... upgrade!

That looks slick, how did you do the wiring (basebar + shifters) in the front end without the use of the 5-port junction?

Took me a bit to get these photos for you since it's in another state right now, but if you need another option, this is by far my favorite. Really nice when taking the bars off to put in a travel case as well since all the wires are tucked up there and you don't have to worry about them hanging up on the stem.

Also attached pics of it with the mono and base bar removed.
