I'm somewhat new to cycling but would consider myself a budding enthusiast. Currently, I have a Specialized Dolce, which has pretty entry-level shimano components. I will be upgrading my ride to Specialized Ruby Pro, and my LBS is offering the Ruby Pro with Shimano Dura-Ace components or SRAM Red components.

I tested them out recently, and they both have very different feel to them. I'm looking for opinions about what people think. Any difference in reliability?
