Just had to weigh in on this...........
Seems to me, there are many better choices to put on your bike in terms of ridablility. Certainly the Dura Ace and Suntour Superbe of that era worked better, and the Campy Super Record stuff works the same or better. (AND we don't even want to talk ablut the newer stuff, ha ha ha) I believe the 50th stuff is collectable, and, as was said before, made for display, either in the box or on a show bike.
I'd keep it in its box and someday put in on a one of a kind Italian Stallion (Red, of course!!)
