My bike has a compact double on it, but can take a triple. My shifter still has that extra click in it for the third ring. When I first got my bike, I thought I broke it (fell in the parking lot and the hood moved over). I pushed it back into place, then took off (so embarrassed! ) A block away, I couldn't figure out why my bike wouldn't shift back down, I must have broken it!!! So, I rode back to the shop, and they explained it to me. I had just shifted into the "ghost" ring and had to double click back down

The moral of the story - it should work.
