There's not a compatability problem. The derailleur that came on our Burley Duet was a Suntour XCE. I believe the bar end shifters are Shimano (they're OEM whatever they are).
We currently have a Shimano Deore rear derailleur on it, and it shifts fine. Pre STI, 6 speed indexing, I'm pretty sure the spacing is all the same.
