I like the frame design of "lower end" CF model much more then previous. Thinking about CF 7 (which is around 3699 EUR, which has quite OK wheels I think, new frame, and after that replacing the 105 with some Di2 or SRAM electronic shifting and then adding powermeter as well.

I think that would be the best way budget wise getting the Speedmax with electronic shifting ... Not sure if the H30 base bar is ok with adding electronic shifting aftewards since it has hydraulic brakes ... what do you think?
