I used to ride a lot, campy then sram. I had the first sram stuff. Anyway was injured for years and I'm back and the new stuff is really quiet but.. what the hell is with the thing hanging off my front derailleur. I heard its to align the chain but that doesn't make sense to me. So far it's been a huge pain and I've gotten my chain stuck behind it a couple times: once while riding and the other times because I'll dislodge the chain from the chainring by hand when I go into a store so it's harder to steal. Normally I can just shift to the big ring from this position tand connect the chain but not with this hanging thing. Now it's bent forward from my attempts but still the shifting is fine and the same. I'd like to just remove it since in my mind it does nothing.
