WANTED: Di2 Rim groupset and lightweight carbon rim set

Hi there,

Upgrading my Cannondale Supersix ready to climb some big mountains this year. So what I'm after is:

1. As close to a full set of Di2 rim groupset as possible. Preferably 9070 but I appreciate this is a big ask so whatever is going will be considered!
   
2. A light racey set up of wheels, as low as 1200g if possible. Again, whatever is going will be considered
   
   

Cheers,
Sam
