Thanks moderators for removing that junk.
FYI, I did not start this thread to argue if disc brakes are superior or not, just inquiring about the additional rotational mass and asking about the Giant Defy bike.
I mean, who wouldn't want a shiny new bike with all the latest and greatest components on it, but that doesn't necessarily mean it is a better bike, or that to get one thing, you have to give up another. In this case, more weight on the wheel in exchange for greater stopping power. How many really need more stopping power and is the weight noticeable.... I think we have answered those questions.
Any input on the Giant Defy Advanced Pro2?
I can't offer an opinion with the Giant as I have no experience with it.
As to the additional rotational mass, I'm sure technically on paper/computer there is some difference, having converted a bike from rim to disc I couldn't detect any difference, and suspect it would require lab equipment to quantify. IMO, its a non issue in the real world.
