I have a campy record 8 speed set up on my bike. I would like to go to 10 speeds. I understand that the shifters and rear derailer need to be changed. I got a record ultra 10 set up used but in very good condition. What I am trying to find out is if I must change my rear wheel because it has the 8 speed hub or if the 10 speed hub will work on it with spacers. Any help on this would be great.
