it's pretty straight forward.
1x set of ultrashift campagnolo levers, 10 or 11sp. It's very important that the left lever is ultrashift. The right can be anything, but you might as well buy a complete set of ultrashift levers.
1x J-tek shiftmate
2x avid BB7_road
RD should be shimano with standard cable pull ratio, which means do not use 10sp MTB.
-or-
you can mix whatever the J-tek will allow.
FD is a regular shimano top pull MTB FD. The campy ultrashift lever has just enough cable pull to sweep through the entire range and can trim to any position.
Thanks, your build looks great.
