Shimano STX FD cable routing
I went to replace the cables on my hybrid/commuter and noticed that after replacing the front shifting cable, my twist/grip shifter no longer moves the front derailleur. If I unbolt the cable from the derailleur, the shifter will easily pull and release cable, but once the cable is bolted down to the fd, I can't get it to budge even a little bit. I'm thinking this has to do with the routing of the cable at the derailleur and unfortunately I didn't pay any attention to how it was before. Here are some photos of how I have it now (won't work). Any idea what I'm missing?

Did you place both the shifter and derailleur in the low gear (small chainring) position before attaching the wire?

The cable goes over the top of the der and down to the anchor bolt. Remove the cable and by hand move the cage in and out then track the anchor bolt's arm's movement and make sure the cable is attached in the right direction. Andy.

The cable is miss routed. It needs to go over the der and back down to the anchor bolt arm. If you remove the cable and work the der in and out by hand while tracking the movement of the anchor bolt and arm you'll see that the cable is wrongly attached/routed. Andy

On third thought (and there were problems with posting the first two times) I might be wrong. But the suggestion to watch the anchor arm's movement while manually working the cage to learn from where the cable needs to pull the der is valid.
I do like the suggestion to make sure the lever is in the low position first. Andy

That's strange
Is that the original stock derailer for that bike?
Because in the photos, it appears to be a top-pull, derailer
while your cable is approaching from under the bottom bracket.
now, some front derailer's are dual-pull, with a little pulley on them that redirects the cable to allow opposite direction routing, but I don't see that on yours.
It's often a half-arc of plastic on the opposite side of the pivot that the cable is clamped to.
also, your derailer looks like it's mounted too high above the chainrings.... this isn't the original derailer is it?
also notice the chain catching stud on the outer chainring is in the wrong place, its out in the open instead of behind the crank arm
again more evidence points to this bike being potentially not-stock configuration (franken-bike)
you recently acquire this bike? did the front Ever shift in the first place?
