Ultegra Di2 external Idiots Guide
Postby liamb » Thu Nov 14, 2013 11:54 am
I am doing a bucket list thing and building a new bike from scratch. I have a De Rosa Avant frame (Italian Colours) and I am wanting to fit Ultegra Di2 to the frame. The frame is not set up for internal wiring.
Is there an idiots guide for buying and fitting this Grupo to a frame. I am asking myself dumb questions and I assume others have asked and possibly know the answers.
ie when I buy the Grupo what battery mount do I buy, long or short? is there 1 specific for external?
can I fit a seatpost battery with external wiring?
can you conceal the wiring in tubes/covers on the frame?
can I make my frame internal??
Are there any common things to look out for??
Cheers
Bill

You'll need the long mount, which will attach via the bottle mounts on the down tube. The short mount is for Di2-ready frames that have a dedicated mount, typically under the left chainstay.
- can I fit a seatpost battery with external wiring?
No.
- can you conceal the wiring in tubes/covers on the frame?
Yes, there are stick-on cable covers available.
- can I make my frame internal??
Not without drilling holes, which is not recommended practice.

The external wiring runs on the underside of the downtube and also on the chainstay, there are sticky covers (sort of like very thick duct tape) available in a few different colours (part of the "kit" but available to buy seperately). My bike is black and luckily black is one of the available colours, as is white. Not sure what other colours are available.

A quick look on the internet shows the going price for Ult 6770 Di2 group is around $1300 - $1600 (from o/s so factor in freight/GST and maybe duty), 11spd Ult Di2 6870 is about $1900. DA Di2 9070 upgrade is around $2K and complete group is around $3300.

I will be buying a total kit. On the Merlin Cycles site there are a few options and I just wanted to get the right options. I am keen to try to get a battery into the seat post with the external wiring, but will need to find a good example of a retro fit..

But from the questions you are posting I would suggest a few things
-Stick to the di2 "external cable" kit - except others might criticise how 'ugly' it looks.
-> this way I think you can route your planned internal battery to pop out somewhere at the bottom bracket hole.
What frame do you have?

The frame is a De Rosa Avant.
I have never been someone to think looks matter but I am keen to try to make an internal install work in a samll way to make it "preeetttyyy" but more so to keep the wires in place.
I rode with a bloke today who had an external fit to a Giant and as we were making our way down a fast downhill the cable cover on his down tube came un stuck. I cant comment on the quality of the install but it was not a good look or thing to happen 50km from home. I was only by chance that i had zip ties in my saddle bag other wise he was riding 50km home with loose wires possibly pulling out of the front plug assembly.
My plan at this stage is to try to track down a busted carbon frame and trial drilling holes in the carbon and cutting holes in the bottom bracket hub assembly prior to the real fit. I am thinking of doing a full picture written description "how to" guide by the "know nothing idiot" of how to convert an external to internal. I know there are companies doing it already but I am on a budget and I don't really want the paint redone and the gear cable mounts removed. The frame was dirt cheap as it already have scratches on it.

I'm debating this at the moment with what to do with my 10 speed Ultegra bike (better grave dig an old thread than start a new one). The way I see it is you can drill a few holes, and possibly create structural issues in your frame. Or alternatively, you can run 6800 mechanical gear (or whatever your groupset supports). The other option is to run SRAM Red eTAP with wireless shifting which will fit on any frame type (internal or external). In my case on a 2007 bike this seems excessive.blk077 wrote:Stick to the di2 "external cable" kit - except others might criticise how 'ugly' it looks.
I'm leaning towards drilling holes in my frame, but I know this shocks a lot of people The other problem with drilling holes in a bike frame not meant for internal cabling though is that you still have the cable guides. Unless you were planning on deleting the cable guides and respraying your bike your going to have cable guides regardless. On an old bike frame its sort of like having downtube shifter lugs. You can blank them if you want but they'll still be there and that won't make a bike look pretty.

Wow, I didn't know this is available. My Giant TCR Advanced Zero (from 2012 or 2013) has the battery under there, and the clip is a bit broken and likely to fall off sooner or later. I'd assumed this was a Giant-specific mount and I was in trouble, but is it actually the standard Shimano part?Duck! wrote:- when I buy the Grupo what battery mount do I buy, long or short? is there 1 specific for external?
You'll need the long mount, which will attach via the bottle mounts on the down tube. The short mount is for Di2-ready frames that have a dedicated mount, typically under the left chainstay.
