In my continuing search of deciding on a new rig i've seen some really good deals on closeout 2015 Cannondale Evo's equipped with full 105. I initially set out with intentions of buying ultegra equipped bike as I believed it was much better in every way without having to pay the dura ace premium, but I haven't ridden any new shimano stuff in nearly a decade.

As I understand the regular EVO frames are the same throughout the lineup and only the groupsets differ. I also have the option of buying the 105 bike and getting ultegra group from ribble for pretty cheap. I'd like to really get the overall weight down as much as possible and I believe the EVO frame alone is a great starting point.

Thoughts?
Thanks in advance.
