This is the layout on the seat tube I`m talking about.

Can you take a photo of the top of the bottom bracket, next to the seat tube. There should be another whole for mechanical cabling.

Your frame is Di2 compatible, so that will be the exit hole for a Di2 wire to the front mech.

With regards to mounting the mech, you will need either a clamp on front mech, or you can get a braze on mech and a clamp on mount like this http://www.planetx.co.uk/i/q/FMPXCLAMP/front-mech-band-on-clamp

Often preferable to do it the latter way, as many groupsets come only with braze on mechs.

I'm discovering this and fortunately had found the clamp on mounts to allow for this. Thanks for the heads up though!! This weekends job is to review some "how to internally wire Di2 groupsets" videos as all my other bikes are mechanical.

Hi - thanks for all the help to date. This isn't an instant process as I'm buying bits and pieces as money allows...

Anyway - I now have seat/seat post, stem, handlebars and have gone down the Ultegra Di2 route with hydraulic shimano disk brakes. The frame is all wired up with a seat post internal battery and associated cabling. I now need a way to convert my PF30 68mm wide BB to a Shimano Hollowtech II configuration for the Ultegra cranks. Has anyone any recommendations?

So far I think I can buy a standard PF30 bottom bracket and add shims OR use a converter (like a Praxis screwfit). Are there any other options I'm not aware of? Does anyone have any experience of the up/downsides of any of the solutions?

Looks great - now time to get it muddy. what did you do with the bottom bracket in the end, did you go with the praxis?
Yep. Full spec is:
Ultegra Di2 all around (mid cage rear)
Shimano Hydraulic disc brakes
Ultegra Cranks
Boardman SPD pedals
Boardman Elite handlebars (44) and stem (110)
Sella Italia seat post and saddle.
Kinesis Crosslite V4 wheels.

Total weight: 8.9kgs.

It gets its 1st ride this lunchtime. A quick shakedown 10 mile ride.
