Reilly T325D Di2 Internal Routing

Folks,

I don't suppose anyone has a Reilly T325D with Di2 deployed? I'm going to (hopefully, if they ever reply to queries) buy a frameset and build up a full Dura-Ace Di2 disc setup but had a question about the internal routing.

I want to make it as neat and water resistant as possible. Does anyone know if the Di2 cable I'll need to run from the head tube area to the front and rear mechs and internal battery can be kept 100% within the frame using the internal 4-port junction box? Basically, are there accessible holes in the down, stay and seat tubes within the bottom bracket shell that I can route the Di2 cabling around, once the bottom bracket is fitted? It's not obvious from the pictures and obviously there is less space within titanium tubes than carbon shapes. I'm hoping to avoid any cables outside the frame, other than their exit points for the two mechs.

I'm not as concerned about the cockpit as I'll use the bar-end junction box, wireless module, and handlebars that have decent routing. I can put up with the single Di2 cable running into the down tube.

Cheers in advance!

Err, yes. When the company says a frame is di2 ready, that's what it means.

However, it would be easier to put all the gubbins inside the frame before fitting the bottom bracket. Not sure why you would fit the BB first, or wouldn't just take any fitted BB out if you wanted to fit di2.

Sorry, didn't articulate myself very well there. I'd just noticed some Di2 builds having the cables inside the tubes but then popping out at both ends and having a horrible junction box under the bottom bracket, which is just asking for trouble in the rain. 
 

I would also be doing all the cable routing before installing any hardware, bottom bracket included, so that wasn't what I meant. Having received all the Di2 bits now I didn't appreciate just how small the internal junction box was so shouldn't be an issue having that hidden in a tube somewhere. 
 

Cheers for the reply!

I'm sure that is a thing of the past, downtube certainly looks plenty big enough to fit the junction B box in comfortably. I'm sure a quick phone call would clarify it...

Well, the frameset's now ordered after a chinwag with Mark himself, so build can begin soon. Already collected a sizeable pile of booty/bits so just need frame and wheels to arrive and I'm good to go.

Excellent. Presumably he answered the di2 issues? Let us see the build in progress....

Yes, and all good. I'll get the build documented. Can't wait now. Shame I've got a 4 week wait for the wheels....

While I also definitely prefer the internal junction or SM-BTC1 if there is no other way, Di2 would definitely be fine in the rain.

I mean.. in Road Bike Party 2 they rode a bike into the pool and according to the "Making Of" the Di2 was still working afterwards: https://youtu.be/HhabgvIIXik?t=307 . Also.. the pros have been riding that external junction in the rain too  3

Haha, brilliant! Maybe I won't try it on mine though, hey?  3

hehe, I think I'll also try to avoid pools or any other wet areas :D.

Probably best for the phone too!
