|Can I run a triple Dura Ace front DR with Ultegra triple STI shifters?||yfoiler|

|I am going to use an FSA Gossemer triple crankset on my tandem.
I have a new Dura Ace "triple" front deraileur I would like to use.
I know the Ultegra STI can be set up for a triple crankset, but will it work well with the Dura Ace triple front DR that I already have, or do I have to get an Ultegra triple front DR?
|if it works with Ultegra it will work with DA (nm)||Jekyll|

|The D/A triple front derailleur is designed to run with 53-39-30 chain rings. If your middle ring is bigger than a 39 you might have a problem, I don't know, but it's something to consider. The Ultegra front derailleur is designed for 52-42-30 rings. Generally you can run rings that are somewhat smaller than the derailleur's design, but not necessarilly the other way around.

|This will be interesting then.
The FSA cranks come with 54, 42, 30.
I can change them later if it doesn't work out...or I guess it would be cheaper to get an Ultegra front DR.
