? about DurAce Bar end Shifters, Triple Compatible?

Aman said:

Before I install these I want to make sure they will work. Will
Dura Ace Model SL-BS77 Bar end shifters work with an Ultegra
triple Crank?

Yes. The left/front shifter is a classical friction shifter that
will shift everything (as long as it can pull enough cable, which it
does for Shimano tripple derailleurs).

Quoted message said:

The instructions say that the shifters will only work with Dura
Ace 7700 Derailleurs.

It says "Compatible with RD7700 (9sp) & RD7400 (8sp)", the point
being that the DuraAce derailleurs before RD7700 had a different
geometry (making 8sp steps with 9sp cable pull).

All Shimano 9sp rear derailleurs (like the RD7700 or RD6500) share
the same geometry, thus all Shimano shifters work fine (and the
same) with them.

Quoted message said:

I have Ultegra 6500 Derailleurs, are they compatible, any body
have success or failure with this combination?

Starting with 9sp Shimano offers only DuraAce bar end shifters and
downtube shifters, they work with all Shimano derailleurs.
