I am looking at getting the Giant OCR 1 or the OCR 2. I am a newbie and this will be my first road bike. Is there any reason I should get the 1 over the 2 right now??? I know the componants and all are better, but being a newbie I wasn't sure if I would really notice the difference. I have already ruled out the 3 since I know I don't want any Sora parts. Any help would be appreciated. Thanks.
