I am using SunTour barcons on a 2x6 setup on my Peugeot, and I am delighted with them. My other road bikes have Campag. downtube levers, and my mountain bike has SunTour XC ratcheting thumb shifters, which I run in non-index mode. I did recently wear out the ratchet mechanism of a front shifter, but in other respects I am a happy camper.
