I have tried to find out if it is true that Giant make the Specialized frames as I have been told that before but it is still rather sketchy.
I don't really know about specs but I have been told the Giant's got better brakes but the rear gear mech of the Specialised is a model up in Shimano's range and the Specialized has better tyres. (By the way, prices are the same). Anyway, I have tried to list all the known specs of both bikes for those of you who do understand:
