I am having trouble choosing between the CAAD10 and the Synapse 5. Both are aluminum and come with several of the same components. I am looking for a relatively comfortable daily rider that will also perform well on long rides and race well. I want to be able to go. I know that the CAAD10's geometry is considerably racier I just wonder if that causes discomfort on longer rides.

I'm currently riding a Bianchi Eros that was given to me. The bike a little too big. I'm 5'2- 5'3 and weigh about 100 pounds. I plan on test riding the Synapse Carbon 5 because it's the only one in the area. Sadly I haven't been able to find any CAAD10's.

Any suggestions or ideas that will help me with my decision?

thanks
