2007 Specialized Tricross Comp with a triple. This past summer I replaced the FSA crank with a 105 triple just because. No issues, everything was fine. I've never really had a problem adjusting a triple.

In the past few weeks I've been having a problem with skipping the middle ring when shifting from the big…chain will sometimes just skip right on over to the small ring leaving me spinning like crazy. Then I'll put it back in the big ring just to test and shift it big to middle / big to middle over and it works fine.

So then I"ll ride along for a while, back in the big ring riding, then the dang thing will skip the middle again. So I'll shift it a few times in a row and it works fine.

Frustrating as hell. Have had it on the stand several times, works fine.

It seems like every time it skips the middle ring that the shifters are hard to shift - and they make a very loud almost snapping sound vs just a click they normally make when it shifts correctly.

Any thoughts on what to do? Clean the shifter? Could the shifter be bad?
