Disc brakes and rotational mass
With the trend going to disc brakes, what happened to the concern of rotational mass? The disc will certainly add weight to the wheels, albeit in the center, where it will be least noticeable, but there none the less.
Am I missing something here or are the people hopping on the trend wagon? I suppose you could make an argument that the "overall" weight of the bike might (?, is the jury in on that debate?) be less, but I am specifically talking about the rotational mass of the wheels....
Thoughts please, as I am considering a Giant Defy Advanced Pro2, which comes with disc brakes standard.
Anyone have any thoughts about the Giant?
