I am very new to road biking and am looking for a bike to get me started. My budget is small (I am a mommy to two young boys) and don't want to break the bank quite yet. So I am looking for a used bike. I am very petite (4'11", 115lbs). I have located a seller in NJ who is selling two of her bikes: 2007 Fuji Newest 4.0, size 42cm OR 2005 Fuji Finest (size ?) She has told me she is 5'4" (which makes a 42cm seem too small for her) and she has told me that both are 42cm. Although, I have not found any geometry specs for the '05 Finest, only that it came in S,M,L,XL. Does anyone know the measurements on that particular bike? Any thoughts on which is better? On a quick side by side comparison online, it looks as if some of the Finest components are better... but I also don't really know what I'm talking about. http://www.bikepedia.com/quickbike/Compare.aspx?b1=93347&b2=95364 Any advice/thoughts are greatly appreciated.
