Hi everyone. I apologize a head of time if this is an obvious question, but I'm relatively new to the road biking scene. Anyways, I am currently looking into getting a road bike. I have heard and read a lot of wonderful things about the Ultegra components. However, many of the 2010 models that I've looked at have the 105s. Do any of you guys feel that the newer 105 components (2010, 2011) function/operate similarly to the older Ultegra components (2004 and 2005)? Any advice / feedback would be greatly appreciated. Thanks.
