I have a set of Bora and Campy 29/12 shift very well on my Sram etap. Probably better than when I was running my Sram 28/11 from another wheelset. The other thing that surprises me is I dont have to be all that fussy with fine adjustment on the Bora as I swap out them for an Easton Echo when doing sprint training. Then I have to fine tune the RD.
