Panthers007 is right about starting the adjsutment process from the beginning. Shimano has a good site theat has the sequence to use for adjusting the Tiagra FD. My Volpe has a barrel adjuster on the cross tube, which serves the same purpose as the inline adjuster shown in the picture above. I found that getting the right amount of cable tension is important. The following link is to the Shimano site, but the sources mentioned above will give you the same information. The Shimano site does not seem to working tonight, but you can click on Tech Support and then Tech Documents and the y will have the specifics for the Tiagra FD.
