Carbon is freaky. The creaks in the frame are like leaks in a house, the sound comes from nowhere near where the problem is. I tried to isolate my creak by removing items like water bottle cages, pedals, etc. I had a suspicion that it was coming from the rear wheel so I put on another wheel and ding that seems to be it. Not sure why that wheel is an issue, pulled the axle, doesn't seem bent or anything, put it back together and the creak seems to be gone. I'll have to get out for a rain ride today and see.
GB-Thanks for that link, helped me understand the mysteries of creaks, pings, clicks, and groans.
