I am buying my first bike, I have been riding a 17 year old Cannondale that is way to small for me, and have found two bikes that I like very much within my price range. One is a Kona Zing, 2008 model, with 105 front derailer and Ultegra rear. It is brand new and $900. I also rode a 2005 Specialize Allez Elite Triple that has Ultegra front and DuraAce rear. I was really comfortable on both. Could I get anyone's opinion on these two bikes?
