Tight shifter

My wife's cruiser was stuck in the middle ring on the crankset. So, I got out the toolbox to loosen up the cable and make some adjustments to the Shimano SiS front derailleur. Set the inner and outer alignment screws, put the cable back on (what a sonofabiscuit that was). Now, the Grip shifter is too tight to shift gears. I have to put a lot of force to move the shifter so it shifts into the largest ring. Where'd I go wrong?

Nope. I'm thinking the cable is probably too short or seized up and needs to be replaced. Just thought I'd ask here to see if anyone had any suggestions.

Was the problem really because the derailleur not adjusted properly, or was it that the cable had too much friction?

Thought it was due to alignment because it would shift easily between the small and middle rings, just not to the large one. The grip shifter would dial up to "3" with no problem, the derailleur just wasn't moving.

Check the (H) screw , it might be in too far , back it out 1/8 -1/4 turn until the derailleur can move the chain . Check the cable housing it might have dirt or rust in it , spray it with something like WD-40 to flush out ,if not then replace it and the cable .

Does the derailleur move at all on its pivots? Perhaps there is corrosion preventing it from moving. It disconnect the cable and try to manipulate the derailleur directly, by hand. If it doesn't move, or takes a great deal of force to move, hit it up with some penetrating oil to try to loosen things up.

You failed to analyze the problem before moving forward.

Step one is to see if the problem is in the FD, levers, or cables.

Shift to low, then shift the FD bu pulling the cable away from the down tube like a bow string. Does the FD work smoothly, and shift crisply in both directions.

Test the levers, by jamming a wedge (like a pen) into the FD's pantograph to hole it in high gear (or close). Now pull the cable from the frame and work the lever against the hand tension. Move smoothly and easily?

If both the FD and levers check out separately, then possibly the cable is binding.

Whatever turns out to be the cause, dividing and isolating it will have you looking in the right place.

Did you by any chance remove the cable from the anchor bolt? And when you hooked it back up, did you run the cable over or under the little nub by the anchor bolt? If you ran it under the nub, that would explain the hard shifting. The cable needs to go over the little nub which seems odd at first.

Your clue was that you said it wad a pain to hook back up. That sounds like you were trying to run the cable under the nub which seems like it would hold better.

I did remove the cable from the anchor bolt, it was pinched between two plates that the bolt tightened down on. Used a pair of needle nose pliers to pull the cable in between the two plates and hold it tight in order while tightening the bolt. After reading your suggestion, I took the cable out again, but didn't pull it so tight when I reassembled everything the second time. That seems to have been my problem.

Looks like it needed an adjustment to the outer limit and proper tension on the cable. Now it shifts into all three rings... not that my wife ever shifts gears, though.

Did you remember to shift the shifter all the way down before reattaching the cable to the derailleur?

*Edit* Sorry didn't see the final post.
