I'm a beginner to the inner workings of a bicycle and learned today that my front derailleur cable wasn't taut so it wasn't shifting properly in the front. After tensioning the cable I am able to shift from middle to low and back again, however when I try to shift to the largest ring the derailleur cage jams the chain for a second or two before it gets it onto the largest ring. Does anyone have any suggestions on what could be causing this? It definitely doesn't shift as smoothly like from the smallest to the middle and being that this was the first time ever trying to move to the largest ring I have no idea if this is "normal".
On a side question dealing with the front derailleur cage... if the chain is slightly rubbing against the cage when I'm in the smallest cog in the rear, is there anything I can adjust to fix that?
