Demet like those latest bars and I am a fan of Motobecane's, their 23 inch frames fit me very well as I too have a long torso for my frame. As for wheels I will throw out that Swift (Panaracer) makes a very nice 27 X1 3/8 tire that I use on my Nisihiki cresta GT, it's roughly 35 mm width and gives a nice plush ride, that would allow you to keep your wheels and brakes as is. Its called the
Sand Canyon and someone on BF recommended it to me. Panaracer also makes a 27 x 1 1/4 pasela (roughtly 32 mm) that is nice and supple. Good luck with the build and enjoy the ride.
