My road bike is about 5 years old and probably the last of the non-threadless stems was used. What advantages if any if I went threadless with a carbon fork? Would I save a pound, gain durability or reliability? My aluminum fork seems decent enough and the old quill type stem does allow for more adjustability, I just don't want to be doing this for the sake of looking more cool, or the OCP police might come knocking on my door. Your thoughts please.
