Well, I don'l know how or why, but I noticed that the "crank cover" or "adjusting cap" on the non-drive side of my FSA Carbon Pro compact (50-34) crank is missing. I've contacted FSA customer service and I'm awaiting a reply. I can't seem to identify the correct part on their web store.

I'm hoping that FSA will come through with all the info, but in the mean time I thought I would see if the BF community could give me some ideas on how else I might get what I need.
