I just finished going on my first ride with the bike that I just built up from the raw frame. It's got ultegra derailleurs, 105 shifters, 105 crank, ultegra cassette. It rides SO smoooooth and nice. I just love riding that thing. I just wanted to share my joy in successfully building a bike that fits and rides great. For what its worth, so far I would definitely recommend the Performance Titan wheels, which I have. So far they're awesome. The Scattante XRL frame/fork from www.supergo.com is also fantastic so far. It's lightweight, and the carbon fork takes bumps nicely. Man, it's so smooth. You know on TdF when they are real close to the bikes, and you hear that nice "zzzzzzzzzz" sound? Man, it sounds just like that. Woo! Just wanted to share!
PS I'll post pics soon
