With that said, there is the option of using them as friction shifters and it MIGHT be possible to adjust the limiters and have the shifter work with a triple, but that is just a WAG. Definitely would not have index shifting on the front."
I don't know who wrote this but it's absolute nonsense. As SkyDog75 noted, all barend (and downtube) front shifters are friction only and they will work with any double or triple crank.
