The reduction in trim on my new Centaur QS shifter made using a triple very frustrating.
When my crank developed a crack, and needed replacing, I opted for a compact.
If I had been determined to stay with a triple, I would have changed the Centaur QS shifters for Chorus, as Chorus and Centaur still have the ability to trim both ways.
IMHO Campag are really wanting to phase out triples, and so are not terribly bothered about offering the claimed compatibilty with Centaur and below shifters.
