Your original question was clear. My answer stands: 'Square peg. Round Hole"
While there are a few bikes out there that can actually run either rim or disc brakes they are truly the exception- not the rule. Van Dessel did a great job of that for years but it also required swapping the fork and the dropouts on the frame. Not standard operating procedure for Giant.
So - NO. You can not put rim brakes on a frame that is already made for disc brakes.
