Managed to get some free time to get my brakes set up. Routing the cables is very time consumming and to say things are tight is a bit of an understatement. The Di2 cables have been a complete nightmare. The photos in the Scott handbook are a work of fiction as there's no way it'll fit like they show with my 90mm stem (as supplied with the medium frame)
Front brake is a TriRig Omega and the rear is Dura-Ace 7800 (as recommended by Scott). Might eventually change the rear as the clearances are not as bad as I was expecting.
Rest of the build is Dura-Ace 7970 10 speed, Zipp Firecrest Clinchers (404 front and 808 rear), Conti Attack/Force tyres and hopefully the new fully integrated seat/seatpost solution from Dash. The guys from Dash have been very helpful and hopefully the Dash seatpost will allow for Di2 battery cable routing.
Looks like I'm heading towards a 8Kg build complete with pedals (and thats with every bolt changed to either a Titanium or Aluminium one).
Here's some more photos to be going on with:-
Will post some more infomation and photos very soon hopefully
