My road bike has 2011 carbon Centaur shifters, a 2011 alloy rear mech and a Veloce front mech of unknown age. But the front mech is a QS (QuickShift?). The rear gears run like clockwork, but the front mech isn't really playing properly: at first it was OK, but as the cable has stretched slightly I now can't shift off the small ring at all. Before I had to pump the shifts 3-4 times to shift to the big ring, but now I can pump it 10 times - until I can't put any more tension into it - and it doesn't move. I can try and get a bit more tension in the cable - there isn't an adjuster, because I have internal cable routing - so this isn't that easy. But I've also heard that the QS mechs were a dead-end in the product line-up that had a different amount of travel. Would some of my problems be solved by switching to a 2011-era Centaur front mech, or possibly just Veloce? Any help much appreciated.
