Well I'm diving into this experiment as well and ordered a 56 size frame, bbright bb, specialized 6.5 headset bearings and compression cap. Airwolf sent a message a few days after ordering asking for stem and handlebar size and I went with 90 stem and 42 handelbar. I am 6' tall. We'll see how it fits. Thanks to all who provided tips along the way. I am going to follow them in the build process.
