I'm on a trek 2100 WSD. I like it but don't love it. I am really leaning toward the giants. I test rode the TCR and OCR. I just can't decide which feels better. I am definitely going to get composite because I want all the road dampening possible. I will also listen to veronica and look into upgrading the wheels too. Veronica, any wheels you have in mind? As for components, ultegra all the way!
