Most likely the rear der, wheels will directly swap over. Maybe the ft der too depending on braze on or seat tube diameter. The B is very likely to be different although with the correct parts the crank will likely be reusable. The calipers maybe yes or no, dependent on brake reach and mounting method.


What i suggest is to make a list of the giant's specs then next to that a list of the new frame's specs. Please don't ask us to do this for you. But do feel free to ask about the specific spec differences that you uncover. Andy.
