I have a trek mountain bike. The front derailleur will not shift from the largest gear at all. Can someone give me some suggestions as to what to check for.
Thanks in advance.

If it does then set the shifter to the same position as the low gear and reconnect the cable.
Generally take the slack out of the cable before finally clamping.
Now try changing gear. Somewhere, depending on the style of changer, there should be an adjuster to fine tune the cable.
