In response to someone's question on SunTour's offerings in the touring bracket, the bike I currently use is equipped with ST Superbe Pro series front and rear (GT) derailleurs. Both shift very smoothly, and quite well under load with the Sedisport chain. The front derailleur allows the use of a triple crank (I use a 30/46/50) and makes the large tooth difference jump reasonably well. Shifting from the middle to the large and vice versa is very smooth. I have not used a Duopar, so I can't compare the Superbe with that, but compared to a ST Cyclone GT, is handles shifting under load better, although both would rather you not do that. Regular shifting is also very smooth, and does not require too many fine tuning moves. The shifting, besides being smooth, is quite "solid" and precise, with a good thunk sound upon engaging the next gear.
