$35 later don't be surprised if it doesn't work. It may be okay. For $35 you can buy a very good SunTour or a Shimano Crane GS that will do what you want better. My 1974 Paramount full Campy has its Rally in an box should I want to sell it. I use a Crane GS which works about ten times as good as the Campy did. Thats because I want to ride the bike. Its your bike to do with as you please. Roger
