Bianchigirll,
the RSD RD is in great shape, I installed 20$ worth of jockeys wheels, tried on another build a year ago, shifts like butter. The stem is an issue but I have the following from the last build (too big of a frame) that i just sold. Nitto Technomic Stem, Tall, 26.0 Clamp will take care of that. here's a pic of the stem with the Tektro brake levers.
Also my Tektro brake levers are much better than most levers i tried up to now. What a great design efficient and cheap. After the rush of bringing the Bianchi home I'll probably just do the basic rebuild and the necessary changes (tires, brake pads etc. and just ride it). As far as the quality of frames made for Bianchi in Japan I will let you know.
More pics of the build in a few weeks.
Cheers
