I cannot answer your question but I would suggest changing the title of your thread to be an actual question (i.e. "Anyone using Dura Ace BS79 shifters with Ultegra 6700 FD"?). From the title, it kinda sounds like you are trying to sell them, like one of those new ST members who didn't read the rules of the classifieds or just doesn't feel like following them.

I would not be surprised if someone who could answer your question might skip the thread thinking the same thing

Good call. Thanks. I do my best to follow the rules

I think I've run that set-up. The FD shifter is just friction anyway so you are setting the position, no "indexing".

edit: I guess I've only run the SL-BS78, but I think the only change is they got rid of the friction option for the RD.

I don't have any problems with mine. Going on a year and a half. I didn't know they weren't compatible.
The b79 brake levers are a lot better with the 6700 brakes.
What is the other choice for shifters if the 79's are not compatible?

As an aside, I recently set up regular 7900 brifter/shifters and found that I could not get the Ultegra front D tuned properly. Did some reading and discovered the incompatibility. Got a 7900 FD and it worked. On the brifters, they removed the trim click and reshaped the FD somehow. In any event, I came to believe for regular road shifters, it does make a difference. Although for a friction system on a TT setup, I can't see how it would make a difference, you just may need to trim the FD as you move across the RD.

Velo thanks for your response.

Question for anyone - why does some of the 6700 tri/tt 8 piece group sets come with the bs79 shifters and the ultegra 6700 front derailleur if they're not "compatible"?

Thx Tom

Let me caveat my earlier post - if you were running a TT group with a front friction shifter in lieu of indexed, then any front d would probably work
