I ran into this problem with the Superbe Pro I have. It does not have an adjuster. I learned that the last generation of the Pro RD does. I came up with an in-line adjuster that I am not happy with. The IRD looks very nice.

The discovery was made when I was in the process of building a Pinarello Tre Cime for my daughter to use. Not having an adjuster was a bit problematic. I used the method [MENTION=157963]canopus[/MENTION] suggested in post #2 . It worked flawlessly with the index DT shifters. Prior to the pic I installed an adjuster that has a very small range. The bike needs to be painted, but that is another thread.
