How do they attached? What do they look like off the
bike? How are they installed? Can they be "tightened" ?

Any info appreciated.

they are a nut insert. If loose, sometimes they can be tightened, but be very careful whom you select to do the job. Some styles can be tightened with a special oversized "rivet gun" like those used to install the rivets that hold window mechanisms to the glass in some car window applications. In a thin frame it is easy to damage the tube if you are not best advice is to find a frame builder to do it for you!
