Have bike, will travel
Are Shimano Dura Ace 10-speed SL-BS78 bar-end shifters campatable with triples?
I can't find this info on the web or on the instruction manual.
Here is a source that says they are: http://www.bicyclebuys.com/drivetrai...Road/1428802BS
Googled right up.
Makes me wonder though since the D-A triple has been dropped.
Barend shifters are all friction for front shifting so any bar end will work with either a double or triple crank of any make or model. I've never seen one yet that can't roll up enough cable to cover a triple.

I currrently have one of those shifters controlling a QUAD crankset on our tandem (24-32-42-54), and the shifter still has a tiny bit more movement available than the front derailleur will allow with the limit screws removed. So, a triple is easy in comparison.
