Hi, I am in the market for a road racing/performance bike. (I have mountain biked until now). I am looking at the 09 Cannondale Synapse Carbon 5 (Women's), The 09 Kona Lisa RD, or the Giant Avail 1 Women's. The cannondale is a full carbon frame and the other two are aluminum/carbon. Seems like compariable parts. Any suggestions???
