I've got a fairly new 2 ring 10 speed with a front derailleur that won't adjust on the outside. The inside screw moves the derailleur in its range, but the outside screw as no effect when twisted all the way in or out. Bike has an inline cable tensioner for the front derailleur that works, but seems to have some kind of malfunction.

In searching for the problem, I found a couple other threads where cable tension was the culprit. So I loosened the inline tensioner a bit and went back to the inside cogs and checked for cable tension- sure enough, it was pretty loose. So I happily whistled a tune as I adjusted the cable and got it nice and snug.. and, adjusting my inline cable tensioner, observed the derailleur in basically perfect position.

Verifying my fix had given it what it needed to work properly, I attempted to bring it in (toward the chain), running through the adjustment procedure as I know it...... nothing. Still no movement at all. Attempted to adjust out, screwing the other way... back the screw out until the head was a couple MM off the derailleur- absolutely no movement. Then, running it through the range of gears again, I noticed it rubs pretty decently on the outside when crossing from smallest ring to largest cog... so I think even though I got everything lined up via cable tension, the derailleur itself still needs adjustment.

What's next? Sledge hammer?
