Please excuse my ignorance in this new sport for me. I'm really lost in all the spec details of these bikes. Can someone please please help me chose the better of these two bikes. http://www.nashbar.com/webapp/wcs/stores/servlet/mProduct4_10052_10053_565120_-1_catNav or http://www.bikesdirect.com/products/motobecane/fantom29_sport_xiii.htm or recommend something in this price range. They are both identical in price after a promo today at Nashbar. Please give me some pros and cons of both. Thanks much in advance.
