Seeing this tandem makes me wish I had gotten off my butt and shipped mine to the show.(Cyfac asked) Although, I'm frustrated that they finally did the internal cable routing that I had asked for 18 months ago.
I may try the new Campy EPS on my tandem later this year, once the supply chains level out enough to find some deals. I do wish it were available in a triple. Fortunately, my part of Texas is flat and any 12%+ grades are less than 1/4 mile.
